The range of linear drainage systems is further enhanced by new innovative products such as Traffic Drain, Landscape Drain, Max-E-Channel inlaid covers and Slot Drain. Most importantly, with Marshalls, the optimum economical drainage design can be readily achieved. All Marshalls systems comply with the requirements, of the appropriate standard; BS EN 9001, the Highway Agency’s Specification for Highway Works together with the requirements of British Standard, BS EN 1433:2002. BS EN 1433:2002 Marshalls’ policy is to manufacture products that, as a minimum requirement, comply with the relevant European, British or Company Standard as appropriate. Following the publication of any European Standard the government recognises that there is a period whereby manufacturers need to realign their product offer, quality control and in many cases the manufacturing operations. INTRODUCTION Almost all impermeable surfaces require some form of surface water drainage. Highways, service and storage facilities, car parks and pedestrian areas are best accommodated by either combined kerb and drainage or linear drainage systems bearing in mind location, efficiency, traffic loading, maintenance and aesthetics. Marshalls is one of the leading suppliers of drainage products and offers a comprehensive range of surface water drainage systems to cater for all applications. Marshalls also understands the design principles of Sustainable Urban Drainage Systems and particularly how designers can achieve sustainable drainage solutions using linear drainage systems or impermeable pavement design or an appropriate combination of both systems as the project requires. Two combined kerb and drainage systems are available - the original, well established Beany Block and now the recent addition of a smaller version, appropriately named Mini Beany. These are complemented by the large capacity Max-E-Channel and Birco Linear drainage systems. This comprehensive range of drainage options allows the designer to cater for: • Long lengths of highway (several kilometres depending on carriageway width and gradient) • Large or small paved areas • High storm water intensities
It is Marshalls' intention that the manufacture of all its linear drainage products complies with BS EN 1433:2002 within the required time frame. The load classification system documented in this Standard is referenced throughout this Design Guide. Details of product specific requirements are published in the product data sheets. DESIGN GUIDANCE AND CAD Marshalls Computer Aided Design service can be called upon by specifiers and contractors alike in relation to the detailing of Marshalls Drainage products. The drawings are created in consultation with the Design Team. Contact [email protected]

THE CASE FOR LINEAR DRAINAGE
THE CASE FOR LINEAR DRAINAGE INTRODUCTION The growing demand for more cost-effective and less complicated drainage systems has led to modern linear drainage becoming the preferred choice amongst specifiers and contractors alike. Marshalls’ unique linear drainage systems combine the clear-cut advantages of linear drainage over traditional point drainage, with the benefits of a high quality, robust precast concrete product. SURFACE WATER INTERCEPTION • More efficient at intercepting running water • Ponding is reduced or eliminated as is streaming water across a site SHALLOW DEPTH OF CONSTRUCTION • Inherently shallow construction required • Savings due to reduced excavation • Reduces construction time, offering further savings • Less conflict with existing underground services • Reduced quantities of spoil to be disposed of
INTRODUCTION
EASE OF DESIGN Performs more efficiently with just the use of concrete channels, grates, outfalls and reduced amounts of pipework. • Only requires shallow depth construction • Limited number of components required • Does not require complex crossfalls to be incorporated • Design of crossfalls and longitudinal falls of adjacent hard landscaping is straightforward • Improved end user performance
8
EASE OF INSTALLATION • Channel line and level can be set out with ease • Crossfalls are less complex to set out or construct compared with point drainage • Expensive construction time saved due to shallow construction • On-site errors are easier to avoid • Unlike other options, Marshalls’ systems do not require temporary ballast (e.g. sand) during installation • Inherently strong and robust precast concrete reduces on-site damage SIGNIFICANT COST SAVINGS BY REDUCING CARRIER PIPES • Many schemes can utilise the inherent ability of a channel or combined kerb and drainage system to act not just as the traditional gully in point drainage, but also as the carrier pipe in storing and transporting surface water. • Any carrier pipes will be at a shallower depth with resultant cost savings • Fewer expensive manholes required • Less spoil to be removed from site • Improved health and safety on site through reduced need for deep excavation work
Fig. 1 Typical point drainage system, illustrating the need for complex crossfalls with attendant implications for design, installation and cost
Fig. 2 Typical equivalent linear drainage system
STORAGE OF SURFACE WATER Linear drainage can utilise the storage capability of its channels to good effect where there are limitations placed on the total outflow of the scheme. This temporary storage facility has been utilised to: • Attenuate peak flows • Avoid or reduce costs of balancing ponds or reservoirs • Reduce pipework sizes at outfalls REDUCED MAINTENANCE • Easier and less costly to maintain than other forms of surface water drainage systems • Easy to access along the whole length of the linear drainage system via removable gratings or regular access points • Blockages will not completely disrupt the whole system and can be dealt with easily • Inherently strong and robust precast concrete systems resistant to the effects of freeze thaw and de-icing salts AESTHETICS • Wide choice of decorative metal gratings or textured and coloured top blocks to enhance the aesthetics of a scheme • Straight lines of linear drainage can be incorporated into the overall design CONTROL OF SPILLAGE • Allows total control of unwanted liquids in an emergency END USER COMFORT • Eliminates false falls and consequent ‘roller coaster’ effect for vehicular traffic associated with point drainage • Level surface offers greater comfort to pedestrians

There are therefore two elements to any linear drainage design; a determination of the peak run-off or maximum flow along and out of the channel and a determination of the system’s maximum capacity.
THE MODIFIED RATIONAL METHOD The Modified Rational Method (often referred to as The Wallingford Procedure) is considered more accurate for larger schemes with longer drainage runs. Whilst the method

THE SIMPLE AREA RUN-OFF METHOD
INTRODUCTION
In the Simple Area Run-Off Method, it is assumed that the whole of the drained area contributes to the peak flow, that the rainfall intensity is uniform over the whole area and additionally that a value for the rainfall intensity is actually assumed. Therefore the assumed value for rainfall intensity is directly proportional to the peak run-off. A balance is often made between cost and the level of performance required but it is generally accepted that this method will yield conservative results. The peak run-off formula used in this method is:-
Analysis of water flow along a linear drainage system where water continuously enters the system laterally is complex and differs in some respects to flow in circular pipes. It is usual to assume that flow in pipes is uniform or steady as the “flow in” equates to the “flow out” and that as the parameters along the system will generally remain unchanged, the flow is essentially unaltered. For these conditions, flow capacity has been determined from traditional methods such as the Colebrook-White formulae.
Q = A x i/3600, where

applications the capacities quoted were realistic and accurate. However, Colebrook-White gave very conservative figures for shallow gradients or flat applications and more cost-effective designs can be completed using data derived from the HR Wallingford work. The theory and practical application of flat channel flow is confirmed in TRL Report 602. Flow data contained in the Marshalls Drainage Design Guide are derived from both HR Wallingford research and from traditional methods. Each system’s data will indicate its source.
CROSS FALLS AND DRAINED WIDTHS
DESIGN PRINCIPLES
assumed location at the outfall upstream towards the head
Generally, cross falls should be between 1 in 40 to 1 in 80 whilst the maximum drained distance to any linear drainage should typically not exceed 50m. OUTFALLS As indicated the location of outfalls is sometimes not determined by the hydraulic design. Where the choice of outfall location is within the designer’s control, and particularly where long drainage runs are being designed, the capacity of the outfall pipe work can sometimes limit

DESIGN CAPACITIES When using inbuilt fall Channels exclusively or in combination with flat invert Channels, drainage capacities should be calculated at the nearest upstream prime invert depth Channel. OTHER CONSIDERATIONS There are other aspects of linear drainage design beyond the

factors given above. These include:
Wallingford’s research confirmed that velocities flows as low as 0.4m/s “caused silt to move”. EXISTING DRAINAGE The location of existing drainage systems may often determine the location of the linear drainage outfall. This may or may not coincide with the most cost effective or efficient linear drainage design. GROUND LEVELS Existing ground levels will determine low points and gradients, particularly so for roads and highways. This can mean that outfall locations are not determined by the hydraulic design. Where the channel longitudinal gradients

Channels with inbuilt falls can be used (Fig. 12 opposite).
INBUILT FALLS Mini Beany, Traffic Drain, Landscape Drain, Slot Drain and Birco are all available with inbuilt falls. Inbuilt fall Channels increase drainage discharge capacity by improving flow rates and thereby increasing the overall discharge capacity of the system. Channels with inbuilt falls have benefits in a number of specific applications: •
In flat areas, such as supermarket car parks, where pavement falls must be minimised to prevent “runaway trolley” syndrome
•
Adjacent to buildings where architectural detail dictates
•
To maintain a level pavement adjacent to internal flooring
PRIME INCREMENTAL DEPTH A set of 20 No. inbuilt fall channels* take the system from the shallowest to the deepest constant depth channel in increments. For most of the Birco systems (Lite, 100 and 150), Mini Beany, Traffic Drain, Landscape Drain and Marshalls Slot Drain, the increment is 10mm per metre long channel (1%). For Birco 200, the increment is 5mm per metre long channel (0.5%). These increments correspond to the various constant depth or invert channels “prime depths” of 0/0, 5/0, 10/0, 15/0 and 20/0 (or 185, 235, 285, 335 and 385 for Mini Beany and Traffic Drain) every 5 linear metres (Fig. 16 opposite). * Birco Lite 15 only

Inbuilt fall Channels are designed as a 20 Channel set (20 linear metres)* but are manufactured individually and can be ordered in any permutation. They can be laid in virtually any given length in combination with constant depth invert Channels (Fig. 16 opposite). Inbuilt fall channels may also be laid to a gradient to increase the invert slope and flow capacity. * Birco Lite 15 only

The cleaning process shall be repeated where necessary after the completion of any remedial works. 10. When used in conjunction with the Manual of Contract Documents for Highway Works, reference should be made to Appendix 5/5. For works not carried out under the above specification, it may be necessary to clarify cement mortar in accordance with BS EN 998-2 and concrete ST1, ST4 and grade C25/30 as specified in BS 8500-1 & 2 and BS EN 206-1. 11. Installation operations should be discontinued if weather conditions are such that the performance of the Mini Beany may be jeopardised. Installation should not be undertaken when the temperature is below 30C on a falling thermometer and below 10C on a rising thermometer. 12. All necessary Personal Protective Equipment (PPE) should be worn on site, as the site rules dictate. Goggles, ear protection, dust masks and protective footwear must always

Too thin a layer of mortar will not allow sufficient sideways movement of the units to achieve an acceptable alignment. 2. It is not necessary for Top and Base Unit vertical joints to line up. 3. Where Max-E-Channel is laid on or adjacent to existing or proposed concrete slabs, transverse joints shall be formed within the units and haunching adjacent to the slab joints and also longitudinal movement joints between the haunching and the slabs. Where necessary, Top Unit drainage apertures shall be protected against the ingress of material during concreting operations.
INTRODUCTION The following specification covers the complete Max-EChannel system including ancillary fittings and is compatible with the Standard Detail sheets. Where the Manual of Contract Documents for Highway Works is used, information for “Appendix 5/6: Linear Drainage Systems” is available on request. MAX-E-CHANNEL 1. The linear drainage system shall be Max-E-Channel, manufactured in pre-cast concrete, with the exception of certain fitments of cast iron or galvanised steel as supplied by Marshalls, Halifax HX5 9HT in accordance with Standard Detail Sheets. 2. The linear drainage system shall consist of a two part system consisting of top units of plain concrete/reinforced concrete/galvanised mild steel/cast iron* together with base units that are 205/295/365/630mm* deep. The overall width of the system is not less than 430mm. 3. All components of the Max-E-Channel system, shall comply with the British Standard BS EN1433, Load Classification as follows: (i) Plain concrete top units to C250* (ii) Reinforced concrete top units to E600* (iii) Cast iron top units to F900* (iv) Inlaid steel top units to D400* 4. The system shall have a minimum of 11,200mm²/m water inlet aperture area. 5. When installed, the minimum depth of construction above the top of the base unit to the drained area surface level shall be not less than 150mm. 6. The linear drainage system comprising straight top and base units, outfalls, silt traps, access covers, junctions, end caps and sealant shall be installed to the line and levels indicated in the contract documents and in accordance with the manufacturer’s instructions and Standard Details.
be worn whenever cutting operations are undertaken. Note: * delete as required
MAX-E-CHANNEL
4. Outfalls, Silt Traps and Access Covers shall be constructed in accordance with the Standard Detail Sheet using the appropriate type of Base Unit. Units shall be bedded on sufficient M-Flex sealant over a gully pot, Outfall Unit or vertical pipe, to make a watertight joint. Where necessary in-situ concrete benching shall be shaped to the full depth of the Base unit. In Silt Traps, the pipe shall be bedded into mix ST4 concrete which shall be fully compacted to make a watertight seal. 5. In situ concrete haunching or surround should not be placed until the installed units have been inspected and approved by the Engineer. The haunching/surrounding should be carried out as one operation to complete lines of Top and Base Units in accordance with the Standard Detail Sheet. 6. Adjacent carriageway and/or footway construction shall not be commenced within 3 days of any jointing or haunching/surrounding concrete being placed. Base Units, Outfalls or Junctions not covered by fully bedded Top Units or covers and frames, shall be adequately supported against loadings imposed by construction traffic. 7. On completion of the works, the Max-E-Channel System shall be cleaned out by high pressure water jetting (100-150 bar at 200 l/min minimum) and left free from obstructions and all Outfalls and Silt Traps shall be emptied. Top Unit drainage apertures shall be covered by timber boards or other approved method, during jetting operations. The cleaning process shall be repeated where necessary after the completion of any remedial works. 8. Installation operations should be discontinued if weather conditions are such that the performance of the Max-EChannel may be jeopardised. Installation should not be undertaken when the temperature is below 30C on a falling thermometer and below 10C on a rising thermometer. 9. All necessary Personal Protective Equipment (PPE) should be worn on site, as the site rules dictate. Goggles, ear protection, dust masks and protective footwear must always

Again, starting at the Outfall, the Units should be set directly onto a liberal quantity of stiff, cement mortar (or M-Bond epoxy mortar* where specified) to completely fill the whole of the joint. Cement mortar shall be Class 12 in accordance with BS EN 998-2. These should be tamped into position close to previously laid Units and the alignment checked. The levels should be checked using the string line and a spirit level. In addition, the general alignment should be checked from all directions as each unit is laid. Surplus mortar shall be

NOTES 1. In order to obtain a ‘good line’, it is very important to lay the Top Units on the specified thickness of compacted mortar using the string line and Base Units as a guide. Too thin a layer of mortar will not allow sufficient sideways movement of the units to achieve an acceptable alignment. 2. It is not necessary for Top and Base Unit vertical joints to line up. 3. Where Traffic Drain is laid on or adjacent to existing or proposed concrete slabs, transverse joints shall be formed within the units and haunching adjacent to the slab joints and also longitudinal movement joints between the haunching and the slabs. Where necessary, Top Unit drainage apertures shall be protected against the ingress of material during concreting operations. 4. Outfalls, Silt Traps and Access Covers shall be constructed in accordance with the Standard Detail Sheet. In Silt Traps, the pipe shall be bedded into mix ST4 concrete which shall be fully compacted to make a watertight seal.

INTRODUCTION Installation of the Marshalls’ Slot Drain System should be carried out in accordance with the Specification and Standard Detail Sheets. The following method of installation is recommended. EXCAVATION Sufficient material should be excavated to accommodate the drainage channels, concrete bedding and haunching, any ‘soft spots’ or poorly compacted formation should be made good. The top of the Slot Drain shall be 5mm below the final pavement surface. Channels and outfall units shall be bedded directly onto a freshly mixed concrete foundation as shown in the Slot Drain Standard Detail Sheets, or alternatively bedded on a layer of Mortar Class 12 to BS EN 998-2:2003 not less than 10mm and not more than 40mm thick on a previously prepared concrete foundation. CHANNELS
OUTFALLS Outfall Units shall be of the type specified in the contract and constructed as shown in the Birco Standard Detail Sheets. Unless otherwise described in the contract, they shall be bedded on and surrounded by 150mm of concrete of the appropriate grade. A suitable section of the wall of the outfall unit shall be cut out to allow adjacent drainage channels to abut without restricting the flow of water. Cutting shall be achieved by using a concrete saw or disc cutter. The horizontal joints between the sections of the outfall units shall be sealed with M-Flex sealant. The appropriate pipe adaptor shall be placed in the aperture for connection to the underground pipework.

Where cutting the Channel Units is required, they shall be cut with a concrete saw or disc cutter, so that no single unit is less than 350mm long. Birco Channels or Slot Drain Top Units shall not be cut unless directed by the Engineer. Any cut galvanised steel shall be renovated using Defcon Z, or similar approved. In situ concrete haunching shall not be placed until the installed units have been inspected and approved by the Engineer. The concrete haunching shall be of a concrete grade appropriate to the Drainage Channel Loading Class as specified in the contract or the Slot Drain Standard Detail Sheets. Haunching shall be carried out as one operation to a complete line of Channel Units, to the dimensions indicated in the Slot Drain Standard Detail sheets. Haunching / surround concrete to the Outfall Unit shall be of the same grade as the adjacent Channel Unit haunching in accordance with the Slot Drain Standard detail sheets. Where channels are laid on or adjacent to existing or proposed concrete slabs, transverse joints shall be formed within the Units and haunching adjacent to the slab joints. Longitudinal movement joints shall also be formed between the haunching and the slabs as described in the contract and in accordance with Slot Drain Standard Detail Sheets.
SLOT DRAIN TOP UNITS Adjacent Carriageway and/or footway construction shall not be commenced within 3 days of any jointing or haunching/ surrounding concrete being placed. Unless agreed with the specifier, Slot Drain Top Units shall be securely bolted to Channel Units having internal depths greater than 150mm, before adjacent pavement construction is commenced. On completion of the works, the drainage channel units shall be cleaned out and left free from obstruction. This shall be carried out either by removal of gratings or by high pressure water jetting (100-150 bar at 200 litres/min minimum). Unless otherwise agreed with the specifier, the slot shall be covered by timber boards or other method during jetting operations. Outfall units shall be emptied. The cleaning process should be repeated where necessary on completion of any remedial works. All bolted Top Units shall be evenly spaced and tightened down securely to the appropriate torque (75 Nm) When Slot Drain is being laid adjacent to flexible small element pavement construction the joints between Slot Drain Top Units must be sealed with M-Tape to avoid any migration of the laying course material.

CONSTRUCTION
CONSTRUCTION INTRODUCTION Installation of the Marshalls’ Landscape Drain System should be carried out in accordance with the Specification and Standard Detail Sheets. The following method of installation is recommended. EXCAVATION Sufficient material should be excavated to accommodate the drainage channels, concrete bedding and haunching, any ‘soft spots’ or poorly compacted formation should be made good. The top of the Landscape Drain shall be 5mm below the final pavement surface. Channels and outfall units shall be bedded directly onto a freshly mixed concrete foundation as shown in the Landscape Drain Standard Detail Sheets, or alternatively bedded on a layer of Mortar Class 12 to BS EN 998-2:2003 not less than 10mm and not more than 40mm thick on a previously prepared concrete foundation.
LANDSCAPE DRAIN
CHANNELS Unless otherwise agreed, Channel Units shall be laid commencing at the outfall to previously established line and level. Setting out pins should be accurately located, with a string line level with the top of the drainage channels. Pins can be located to the rear of the channels to avoid having to lift components over the string line. Channel ends should abut as tightly as possible. The invert and surface levels of adjacent channels shall correspond. Any units deviating more than 3mm in 3m from line and level shall be made good by lifting and relaying. Where cutting of Landscape Drain Channel Units is required, they shall be cut with a concrete saw or disc cutter, so that no single unit is less than 350mm long. Landscape Drain units shall not be cut unless directed by the Engineer. In situ concrete haunching shall not be placed until the installed units have been inspected and approved by the Engineer. The concrete haunching shall be of a concrete grade appropriate to the Drainage Channel Loading Class as specified in the contract or the Landscape Drain Standard Detail Sheets. Haunching shall be carried out as one operation to a complete line of Channel Units, to the dimensions indicated in the Landscape Drain Standard Detail sheets. Haunching / surround concrete to the Outfall Unit shall be of the same grade as the adjacent Channel Unit haunching in accordance with the Landscape Drain Standard detail sheets. Where channels are laid on or adjacent to existing or proposed concrete slabs, transverse joints shall be formed within the units and haunching adjacent to the slab joints. Longitudinal movement joints shall also be formed between the haunching and the slabs as described in the contract and in accordance with Landscape Drain Standard Detail Sheets. 98
OUTFALLS Outfall Units shall be of the type specified in the contract and constructed as shown in the Landscape Drain Standard Detail Sheets. Unless otherwise described in the contract, they shall be bedded on and surrounded by 150mm of concrete of the appropriate grade. A suitable section of the wall of the outfall unit shall be cut out to allow adjacent drainage channels to abut without restricting the flow of water. Cutting shall be achieved by using a concrete saw or disc cutter. The horizontal joints between the sections of the outfall units shall be sealed with M-Flex sealant. The appropriate pipe adaptor shall be placed in the aperture for connection to the underground pipework. JOINT SEALANT Jointing of adjacent channels shall be carried prior to fixing the gratings. Marshalls’ M-Flex sealant should be gunned into the sealant groove formed when adjacent channels abut. Surplus sealant shall be removed from the inner surface of the units as work proceeds. M-Flex shall also be used to seal the vertical joint between top units, to prevent any migration of adjacent laying course material. One tube of M-Flex is sufficient to seal the following:M-FLEX REQUIREMENT Base Type

LANDSCAPE DRAIN TOP UNITS Adjacent Carriageway and/or footway construction shall not be commenced within 3 days of any jointing or haunching/ surrounding concrete being placed. Unless agreed with the specifier, Landscape Drain Top Units shall be bedded securely on to channel units with Mortar Class 12 to BS EN 998-2:2003 as stated in the Landscape Drain Standard Detail Sheets. On completion of the works, the drainage channel units shall be cleaned out and left free from obstruction. This shall be carried out either by removal of gratings or by high pressure water jetting (100-150 bar at 200 litres/min minimum). Unless otherwise agreed with the specifier, the slot openings shall be covered by timber boards or other method during jetting operations. Outfall units shall be emptied. The cleaning process should be repeated where necessary on completion of any remedial works.

Note: All cast iron (Grey and Ductile) gratings are black coated when delivered. This is a temporary coating for aesthetic reasons only. Once installed, the gratings may show signs of surface oxidation. This is not detrimental and will not adversely affect the grating’s performance. If regularly trafficked, the surface will become polished to a dark colour. All gratings should be tightened upon installation to the following torque: Birco Lite – 25 Nm

Where the concrete surround is taken to the surface, the concrete surround should have the appropriate freeze thaw resistance. 5. For high loading applications with poor conditions, consideration may be given to the local thickening of the sub-base. 6. Marshalls’ vertical joint sealant, M-Flex, shall be applied to all vertical joints of the channels. 7. Birco gratings should be chosen to suit the appropriate loading application, taking into account both static and dynamic loading conditions. 8. Movement joints details that fully isolate the Birco system whilst maintaining restraint shall be provided adjacent to all concrete slabs even when the slab is covered by another material. The use of dowel bars in concrete slab joints is common and should be considered especially for higherloading applications. 9. All grating bolts should be tightened to the appropriate torque shown in the Birco section of the Design Guide. 10. The top surface of the grating shall be between 5mm below the final pavement level.

Flat or steep gradients Heavy vehicular loading Shallow depth construction Temporary storm water storage Appropriate aesthetic finishes Minimal maintenance
The range of linear drainage systems is further enhanced by new innovative products such as Traffic Drain, Landscape Drain, Max-E-Channel inlaid covers and Slot Drain. Most importantly, with Marshalls, the optimum economical drainage design can be readily achieved. All Marshalls systems comply with the requirements, of the appropriate standard; BS EN 9001, the Highway Agency’s Specification for Highway Works together with the requirements of British Standard, BS EN 1433:2002. BS EN 1433:2002 Marshalls’ policy is to manufacture products that, as a minimum requirement, comply with the relevant European, British or Company Standard as appropriate. Following the publication of any European Standard the government recognises that there is a period whereby manufacturers need to realign their product offer, quality control and in many cases the manufacturing operations. INTRODUCTION Almost all impermeable surfaces require some form of surface water drainage. Highways, service and storage facilities, car parks and pedestrian areas are best accommodated by either combined kerb and drainage or linear drainage systems bearing in mind location, efficiency, traffic loading, maintenance and aesthetics. Marshalls is one of the leading suppliers of drainage products and offers a comprehensive range of surface water drainage systems to cater for all applications. Marshalls also understands the design principles of Sustainable Urban Drainage Systems and particularly how designers can achieve sustainable drainage solutions using linear drainage systems or impermeable pavement design or an appropriate combination of both systems as the project requires. Two combined kerb and drainage systems are available - the original, well established Beany Block and now the recent addition of a smaller version, appropriately named Mini Beany. These are complemented by the large capacity Max-E-Channel and Birco Linear drainage systems. This comprehensive range of drainage options allows the designer to cater for: • Long lengths of highway (several kilometres depending on carriageway width and gradient) • Large or small paved areas • High storm water intensities
It is Marshalls' intention that the manufacture of all its linear drainage products complies with BS EN 1433:2002 within the required time frame. The load classification system documented in this Standard is referenced throughout this Design Guide. Details of product specific requirements are published in the product data sheets. DESIGN GUIDANCE AND CAD Marshalls Computer Aided Design service can be called upon by specifiers and contractors alike in relation to the detailing of Marshalls Drainage products. The drawings are created in consultation with the Design Team. Contact [email protected]

THE CASE FOR LINEAR DRAINAGE
THE CASE FOR LINEAR DRAINAGE INTRODUCTION The growing demand for more cost-effective and less complicated drainage systems has led to modern linear drainage becoming the preferred choice amongst specifiers and contractors alike. Marshalls’ unique linear drainage systems combine the clear-cut advantages of linear drainage over traditional point drainage, with the benefits of a high quality, robust precast concrete product. SURFACE WATER INTERCEPTION • More efficient at intercepting running water • Ponding is reduced or eliminated as is streaming water across a site SHALLOW DEPTH OF CONSTRUCTION • Inherently shallow construction required • Savings due to reduced excavation • Reduces construction time, offering further savings • Less conflict with existing underground services • Reduced quantities of spoil to be disposed of
INTRODUCTION
EASE OF DESIGN Performs more efficiently with just the use of concrete channels, grates, outfalls and reduced amounts of pipework. • Only requires shallow depth construction • Limited number of components required • Does not require complex crossfalls to be incorporated • Design of crossfalls and longitudinal falls of adjacent hard landscaping is straightforward • Improved end user performance
8
EASE OF INSTALLATION • Channel line and level can be set out with ease • Crossfalls are less complex to set out or construct compared with point drainage • Expensive construction time saved due to shallow construction • On-site errors are easier to avoid • Unlike other options, Marshalls’ systems do not require temporary ballast (e.g. sand) during installation • Inherently strong and robust precast concrete reduces on-site damage SIGNIFICANT COST SAVINGS BY REDUCING CARRIER PIPES • Many schemes can utilise the inherent ability of a channel or combined kerb and drainage system to act not just as the traditional gully in point drainage, but also as the carrier pipe in storing and transporting surface water. • Any carrier pipes will be at a shallower depth with resultant cost savings • Fewer expensive manholes required • Less spoil to be removed from site • Improved health and safety on site through reduced need for deep excavation work
Fig. 1 Typical point drainage system, illustrating the need for complex crossfalls with attendant implications for design, installation and cost
Fig. 2 Typical equivalent linear drainage system
STORAGE OF SURFACE WATER Linear drainage can utilise the storage capability of its channels to good effect where there are limitations placed on the total outflow of the scheme. This temporary storage facility has been utilised to: • Attenuate peak flows • Avoid or reduce costs of balancing ponds or reservoirs • Reduce pipework sizes at outfalls REDUCED MAINTENANCE • Easier and less costly to maintain than other forms of surface water drainage systems • Easy to access along the whole length of the linear drainage system via removable gratings or regular access points • Blockages will not completely disrupt the whole system and can be dealt with easily • Inherently strong and robust precast concrete systems resistant to the effects of freeze thaw and de-icing salts AESTHETICS • Wide choice of decorative metal gratings or textured and coloured top blocks to enhance the aesthetics of a scheme • Straight lines of linear drainage can be incorporated into the overall design CONTROL OF SPILLAGE • Allows total control of unwanted liquids in an emergency END USER COMFORT • Eliminates false falls and consequent ‘roller coaster’ effect for vehicular traffic associated with point drainage • Level surface offers greater comfort to pedestrians

SELECTION PROCESS
COMBINED KERB AND DRAINAGE SYSTEMS
SELECTION PROCEDURE The key deciding factor as to which combined kerb and drainage system to specify will often be flow capacity. The following procedure and graph can be used to determine which of the two Marshalls systems is most appropriate: Step 1
Determine gradient of the system
Step 2
Determine peak flow in the system
Step 3
Refer to graph Fig. 4 (below) to determine which is the most appropriate system
EXAMPLE 1 For a combined kerb and drainage system, with a gradient of 1 in 100, where the calculated peak discharged is 54l/s. Fig. 3 shows that Mini Beany has a capacity of 66 l/s at a gradient of 1 in 100. Refer to the Mini Beany section, page 41, to determine which of the Mini Beany systems to specify.

short runs of linear drainage (less than 200m).
There are therefore two elements to any linear drainage design; a determination of the peak run-off or maximum flow along and out of the channel and a determination of the system’s maximum capacity.
THE MODIFIED RATIONAL METHOD The Modified Rational Method (often referred to as The Wallingford Procedure) is considered more accurate for larger schemes with longer drainage runs. Whilst the method

THE SIMPLE AREA RUN-OFF METHOD
INTRODUCTION
In the Simple Area Run-Off Method, it is assumed that the whole of the drained area contributes to the peak flow, that the rainfall intensity is uniform over the whole area and additionally that a value for the rainfall intensity is actually assumed. Therefore the assumed value for rainfall intensity is directly proportional to the peak run-off. A balance is often made between cost and the level of performance required but it is generally accepted that this method will yield conservative results. The peak run-off formula used in this method is:-
Analysis of water flow along a linear drainage system where water continuously enters the system laterally is complex and differs in some respects to flow in circular pipes. It is usual to assume that flow in pipes is uniform or steady as the “flow in” equates to the “flow out” and that as the parameters along the system will generally remain unchanged, the flow is essentially unaltered. For these conditions, flow capacity has been determined from traditional methods such as the Colebrook-White formulae.
Q = A x i/3600, where

applications the capacities quoted were realistic and accurate. However, Colebrook-White gave very conservative figures for shallow gradients or flat applications and more cost-effective designs can be completed using data derived from the HR Wallingford work. The theory and practical application of flat channel flow is confirmed in TRL Report 602. Flow data contained in the Marshalls Drainage Design Guide are derived from both HR Wallingford research and from traditional methods. Each system’s data will indicate its source.
CROSS FALLS AND DRAINED WIDTHS
DESIGN PRINCIPLES
assumed location at the outfall upstream towards the head
Generally, cross falls should be between 1 in 40 to 1 in 80 whilst the maximum drained distance to any linear drainage should typically not exceed 50m. OUTFALLS As indicated the location of outfalls is sometimes not determined by the hydraulic design. Where the choice of outfall location is within the designer’s control, and particularly where long drainage runs are being designed, the capacity of the outfall pipe work can sometimes limit

DESIGN CAPACITIES When using inbuilt fall Channels exclusively or in combination with flat invert Channels, drainage capacities should be calculated at the nearest upstream prime invert depth Channel. OTHER CONSIDERATIONS There are other aspects of linear drainage design beyond the

factors given above. These include:
Wallingford’s research confirmed that velocities flows as low as 0.4m/s “caused silt to move”. EXISTING DRAINAGE The location of existing drainage systems may often determine the location of the linear drainage outfall. This may or may not coincide with the most cost effective or efficient linear drainage design. GROUND LEVELS Existing ground levels will determine low points and gradients, particularly so for roads and highways. This can mean that outfall locations are not determined by the hydraulic design.

Channels with inbuilt falls can be used (Fig. 12 opposite).
INBUILT FALLS Mini Beany, Traffic Drain, Landscape Drain, Slot Drain and Birco are all available with inbuilt falls. Inbuilt fall Channels increase drainage discharge capacity by improving flow rates and thereby increasing the overall discharge capacity of the system. Channels with inbuilt falls have benefits in a number of specific applications: •
In flat areas, such as supermarket car parks, where pavement falls must be minimised to prevent “runaway trolley” syndrome
•
Adjacent to buildings where architectural detail dictates
•
To maintain a level pavement adjacent to internal flooring
PRIME INCREMENTAL DEPTH A set of 20 No. inbuilt fall channels* take the system from the shallowest to the deepest constant depth channel in increments. For most of the Birco systems (Lite, 100 and 150), Mini Beany, Traffic Drain, Landscape Drain and Marshalls Slot Drain, the increment is 10mm per metre long channel (1%). For Birco 200, the increment is 5mm per metre long channel (0.5%). These increments correspond to the various constant depth or invert channels “prime depths” of 0/0, 5/0, 10/0, 15/0 and 20/0 (or 185, 235, 285, 335 and 385 for Mini Beany and Traffic Drain) every 5 linear metres (Fig. 16 opposite). * Birco Lite 15 only

Inbuilt fall Channels are designed as a 20 Channel set (20 linear metres)* but are manufactured individually and can be ordered in any permutation. They can be laid in virtually any given length in combination with constant depth invert Channels (Fig. 16 opposite). Inbuilt fall channels may also be laid to a gradient to increase the invert slope and flow capacity. * Birco Lite 15 only

Top Unit drainage apertures shall be covered by timber boards or other approved method, during jetting operations. The cleaning process shall be repeated where necessary after the completion of any remedial works. 11. When used in conjunction with the Manual of Contract Documents for Highway Works, reference should be made to Appendix 5/5. For works not carried out under the above specification, it may be necessary to clarify cement mortar in accordance with BS EN 998-2 and concrete mix ST1, ST4 and grade C25/30 as specified in BS 8500-2. 12. Conventional gully gratings should have a maximum overall depth of 140mm to allow bedding over Base Units (as in Access Cover Type 2, Standard Detail Sheet).

The cleaning process shall be repeated where necessary after the completion of any remedial works. 10. When used in conjunction with the Manual of Contract Documents for Highway Works, reference should be made to Appendix 5/5. For works not carried out under the above specification, it may be necessary to clarify cement mortar in accordance with BS EN 998-2 and concrete ST1, ST4 and grade C25/30 as specified in BS 8500-1 & 2 and BS EN 206-1. 11. Installation operations should be discontinued if weather conditions are such that the performance of the Mini Beany may be jeopardised. Installation should not be undertaken when the temperature is below 30C on a falling thermometer and below 10C on a rising thermometer. 12. All necessary Personal Protective Equipment (PPE) should be worn on site, as the site rules dictate. Goggles, ear protection, dust masks and protective footwear must always

Where necessary, Top Unit drainage apertures shall be protected against the ingress of material during concreting operations.
INTRODUCTION The following specification covers the complete Max-EChannel system including ancillary fittings and is compatible with the Standard Detail sheets. Where the Manual of Contract Documents for Highway Works is used, information for “Appendix 5/6: Linear Drainage Systems” is available on request. MAX-E-CHANNEL 1. The linear drainage system shall be Max-E-Channel, manufactured in pre-cast concrete, with the exception of certain fitments of cast iron or galvanised steel as supplied by Marshalls, Halifax HX5 9HT in accordance with Standard Detail Sheets. 2. The linear drainage system shall consist of a two part system consisting of top units of plain concrete/reinforced concrete/galvanised mild steel/cast iron* together with base units that are 205/295/365/630mm* deep. The overall width of the system is not less than 430mm. 3. All components of the Max-E-Channel system, shall comply with the British Standard BS EN1433, Load Classification as follows: (i) Plain concrete top units to C250* (ii) Reinforced concrete top units to E600* (iii) Cast iron top units to F900* (iv) Inlaid steel top units to D400* 4. The system shall have a minimum of 11,200mm²/m water inlet aperture area. 5. When installed, the minimum depth of construction above the top of the base unit to the drained area surface level shall be not less than 150mm. 6. The linear drainage system comprising straight top and base units, outfalls, silt traps, access covers, junctions, end caps and sealant shall be installed to the line and levels indicated in the contract documents and in accordance with the manufacturer’s instructions and Standard Details.

MAX-E-CHANNEL
4. Outfalls, Silt Traps and Access Covers shall be constructed in accordance with the Standard Detail Sheet using the appropriate type of Base Unit. Units shall be bedded on sufficient M-Flex sealant over a gully pot, Outfall Unit or vertical pipe, to make a watertight joint. Where necessary in-situ concrete benching shall be shaped to the full depth of the Base unit. In Silt Traps, the pipe shall be bedded into mix ST4 concrete which shall be fully compacted to make a watertight seal. 5. In situ concrete haunching or surround should not be placed until the installed units have been inspected and approved by the Engineer. The haunching/surrounding should be carried out as one operation to complete lines of Top and Base Units in accordance with the Standard Detail Sheet. 6. Adjacent carriageway and/or footway construction shall not be commenced within 3 days of any jointing or haunching/surrounding concrete being placed. Base Units, Outfalls or Junctions not covered by fully bedded Top Units or covers and frames, shall be adequately supported against loadings imposed by construction traffic. 7. On completion of the works, the Max-E-Channel System shall be cleaned out by high pressure water jetting (100-150 bar at 200 l/min minimum) and left free from obstructions and all Outfalls and Silt Traps shall be emptied. Top Unit drainage apertures shall be covered by timber boards or other approved method, during jetting operations. The cleaning process shall be repeated where necessary after the completion of any remedial works. 8. Installation operations should be discontinued if weather conditions are such that the performance of the Max-EChannel may be jeopardised. Installation should not be undertaken when the temperature is below 30C on a falling thermometer and below 10C on a rising thermometer. 9. All necessary Personal Protective Equipment (PPE) should be worn on site, as the site rules dictate. Goggles, ear protection, dust masks and protective footwear must always

Again, starting at the Outfall, the Units should be set directly onto a liberal quantity of stiff, cement mortar (or M-Bond epoxy mortar* where specified) to completely fill the whole of the joint. Cement mortar shall be Class 12 in accordance with BS EN 998-2. These should be tamped into position close to previously laid Units and the alignment checked. The levels should be checked using the string line and a spirit level. In addition, the general alignment should be checked from all directions as each unit is laid. Surplus mortar shall be

NOTES 1. In order to obtain a ‘good line’, it is very important to lay the Top Units on the specified thickness of compacted mortar using the string line and Base Units as a guide. Too thin a layer of mortar will not allow sufficient sideways movement of the units to achieve an acceptable alignment. 2. It is not necessary for Top and Base Unit vertical joints to line up. 3. Where Traffic Drain is laid on or adjacent to existing or proposed concrete slabs, transverse joints shall be formed within the units and haunching adjacent to the slab joints and also longitudinal movement joints between the haunching and the slabs. Where necessary, Top Unit drainage apertures shall be protected against the ingress of material during concreting operations. 4. Outfalls, Silt Traps and Access Covers shall be constructed in accordance with the Standard Detail Sheet. In Silt Traps, the pipe shall be bedded into mix ST4 concrete which shall be fully compacted to make a watertight seal.

The following method of installation is recommended. EXCAVATION Sufficient material should be excavated to accommodate the drainage channels, concrete bedding and haunching, any ‘soft spots’ or poorly compacted formation should be made good. The top of the Slot Drain shall be 5mm below the final pavement surface. Channels and outfall units shall be bedded directly onto a freshly mixed concrete foundation as shown in the Slot Drain Standard Detail Sheets, or alternatively bedded on a layer of Mortar Class 12 to BS EN 998-2:2003 not less than 10mm and not more than 40mm thick on a previously prepared concrete foundation. CHANNELS
OUTFALLS Outfall Units shall be of the type specified in the contract and constructed as shown in the Birco Standard Detail Sheets. Unless otherwise described in the contract, they shall be bedded on and surrounded by 150mm of concrete of the appropriate grade. A suitable section of the wall of the outfall unit shall be cut out to allow adjacent drainage channels to abut without restricting the flow of water. Cutting shall be achieved by using a concrete saw or disc cutter. The horizontal joints between the sections of the outfall units shall be sealed with M-Flex sealant. The appropriate pipe adaptor shall be placed in the aperture for connection to the underground pipework.

Birco Channels or Slot Drain Top Units shall not be cut unless directed by the Engineer. Any cut galvanised steel shall be renovated using Defcon Z, or similar approved. In situ concrete haunching shall not be placed until the installed units have been inspected and approved by the Engineer. The concrete haunching shall be of a concrete grade appropriate to the Drainage Channel Loading Class as specified in the contract or the Slot Drain Standard Detail Sheets. Haunching shall be carried out as one operation to a complete line of Channel Units, to the dimensions indicated in the Slot Drain Standard Detail sheets. Haunching / surround concrete to the Outfall Unit shall be of the same grade as the adjacent Channel Unit haunching in accordance with the Slot Drain Standard detail sheets. Where channels are laid on or adjacent to existing or proposed concrete slabs, transverse joints shall be formed within the Units and haunching adjacent to the slab joints. Longitudinal movement joints shall also be formed between the haunching and the slabs as described in the contract and in accordance with Slot Drain Standard Detail Sheets.

Unless agreed with the specifier, Slot Drain Top Units shall be securely bolted to Channel Units having internal depths greater than 150mm, before adjacent pavement construction is commenced. On completion of the works, the drainage channel units shall be cleaned out and left free from obstruction. This shall be carried out either by removal of gratings or by high pressure water jetting (100-150 bar at 200 litres/min minimum). Unless otherwise agreed with the specifier, the slot shall be covered by timber boards or other method during jetting operations. Outfall units shall be emptied. The cleaning process should be repeated where necessary on completion of any remedial works. All bolted Top Units shall be evenly spaced and tightened down securely to the appropriate torque (75 Nm) When Slot Drain is being laid adjacent to flexible small element pavement construction the joints between Slot Drain Top Units must be sealed with M-Tape to avoid any migration of the laying course material.

CONSTRUCTION
CONSTRUCTION INTRODUCTION Installation of the Marshalls’ Landscape Drain System should be carried out in accordance with the Specification and Standard Detail Sheets. The following method of installation is recommended. EXCAVATION Sufficient material should be excavated to accommodate the drainage channels, concrete bedding and haunching, any ‘soft spots’ or poorly compacted formation should be made good. The top of the Landscape Drain shall be 5mm below the final pavement surface. Channels and outfall units shall be bedded directly onto a freshly mixed concrete foundation as shown in the Landscape Drain Standard Detail Sheets, or alternatively bedded on a layer of Mortar Class 12 to BS EN 998-2:2003 not less than 10mm and not more than 40mm thick on a previously prepared concrete foundation.
LANDSCAPE DRAIN
CHANNELS Unless otherwise agreed, Channel Units shall be laid commencing at the outfall to previously established line and level. Setting out pins should be accurately located, with a string line level with the top of the drainage channels. Pins can be located to the rear of the channels to avoid having to lift components over the string line. Channel ends should abut as tightly as possible. The invert and surface levels of adjacent channels shall correspond. Any units deviating more than 3mm in 3m from line and level shall be made good by lifting and relaying. Where cutting of Landscape Drain Channel Units is required, they shall be cut with a concrete saw or disc cutter, so that no single unit is less than 350mm long. Landscape Drain units shall not be cut unless directed by the Engineer. In situ concrete haunching shall not be placed until the installed units have been inspected and approved by the Engineer. The concrete haunching shall be of a concrete grade appropriate to the Drainage Channel Loading Class as specified in the contract or the Landscape Drain Standard Detail Sheets. Haunching shall be carried out as one operation to a complete line of Channel Units, to the dimensions indicated in the Landscape Drain Standard Detail sheets. Haunching / surround concrete to the Outfall Unit shall be of the same grade as the adjacent Channel Unit haunching in accordance with the Landscape Drain Standard detail sheets. Where channels are laid on or adjacent to existing or proposed concrete slabs, transverse joints shall be formed within the units and haunching adjacent to the slab joints. Longitudinal movement joints shall also be formed between the haunching and the slabs as described in the contract and in accordance with Landscape Drain Standard Detail Sheets. 98
OUTFALLS Outfall Units shall be of the type specified in the contract and constructed as shown in the Landscape Drain Standard Detail Sheets. Unless otherwise described in the contract, they shall be bedded on and surrounded by 150mm of concrete of the appropriate grade. A suitable section of the wall of the outfall unit shall be cut out to allow adjacent drainage channels to abut without restricting the flow of water. Cutting shall be achieved by using a concrete saw or disc cutter. The horizontal joints between the sections of the outfall units shall be sealed with M-Flex sealant. The appropriate pipe adaptor shall be placed in the aperture for connection to the underground pipework. JOINT SEALANT Jointing of adjacent channels shall be carried prior to fixing the gratings. Marshalls’ M-Flex sealant should be gunned into the sealant groove formed when adjacent channels abut. Surplus sealant shall be removed from the inner surface of the units as work proceeds. M-Flex shall also be used to seal the vertical joint between top units, to prevent any migration of adjacent laying course material. One tube of M-Flex is sufficient to seal the following:M-FLEX REQUIREMENT Base Type

Unless agreed with the specifier, Landscape Drain Top Units shall be bedded securely on to channel units with Mortar Class 12 to BS EN 998-2:2003 as stated in the Landscape Drain Standard Detail Sheets. On completion of the works, the drainage channel units shall be cleaned out and left free from obstruction. This shall be carried out either by removal of gratings or by high pressure water jetting (100-150 bar at 200 litres/min minimum). Unless otherwise agreed with the specifier, the slot openings shall be covered by timber boards or other method during jetting operations. Outfall units shall be emptied. The cleaning process should be repeated where necessary on completion of any remedial works.

Note: All cast iron (Grey and Ductile) gratings are black coated when delivered. This is a temporary coating for aesthetic reasons only. Once installed, the gratings may show signs of surface oxidation. This is not detrimental and will not adversely affect the grating’s performance. If regularly trafficked, the surface will become polished to a dark colour. All gratings should be tightened upon installation to the following torque: Birco Lite – 25 Nm

Where the concrete surround is taken to the surface, the concrete surround should have the appropriate freeze thaw resistance. 5. For high loading applications with poor conditions, consideration may be given to the local thickening of the sub-base. 6. Marshalls’ vertical joint sealant, M-Flex, shall be applied to all vertical joints of the channels. 7. Birco gratings should be chosen to suit the appropriate loading application, taking into account both static and dynamic loading conditions. 8. Movement joints details that fully isolate the Birco system whilst maintaining restraint shall be provided adjacent to all concrete slabs even when the slab is covered by another material. The use of dowel bars in concrete slab joints is common and should be considered especially for higherloading applications. 9. All grating bolts should be tightened to the appropriate torque shown in the Birco section of the Design Guide. 10. The top surface of the grating shall be between 5mm below the final pavement level.
