8 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 Fig. 1 Typical point drainage system, illustrating the need for complex crossfalls More efficient at intercepting running water with attendant implications for design, installation and cost 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 Ease of design Performs more efficiently with just the use of concrete channels, grates, Fig. 2 Typical equivalent linear drainage system outfalls and reduced amounts of pipework. Only requires shallow depth construction Limited number of components required Does not require complex crossfalls to be incorporated Storage of surface water Design of crossfalls and longitudinal falls of adjacent hard Linear drainage can utilise the storage capability of its channels to good landscaping is straightforward effect where there are limitations placed on the total outflow of the scheme. Improved end user performance This temporary storage facility has been utilised to: Attenuate peak flows Ease of installation Avoid or reduce costs of balancing ponds or reservoirs Channel line and level can be set out with ease Reduce pipework sizes at outfalls Crossfalls are less complex to set out or construct compared with point drainage Reduced maintenance Expensive construction time saved due to shallow construction Easier and less costly to maintain than other forms of surface water On-site errors are easier to avoid drainage systems Unlike other options, Marshalls systems do not require temporary Easy to access along the whole length of the linear drainage system ballast (e.g. Sand) during installation via removable gratings or regular access points Inherently strong and robust precast concrete reduces on-site Blockages will not completely disrupt the whole system and can be damage dealt with easily Inherently strong and robust precast concrete systems resistant to Significant cost savings by reducing carrier pipes the effects of freeze thaw and de-icing salts 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 Aesthetics drainage, but also as the carrier pipe in storing and transporting surface Wide choice of decorative metal gratings or textured and coloured water. top blocks to enhance the aesthetics of a scheme Any carrier pipes will be at a shallower depth with resultant cost savings Straight lines of linear drainage can be incorporated into the Fewer expensive manholes required overall design Less spoil to be removed from site Improved health and safety on site through reduced need for deep Control of spillage excavation work 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 8

9 Selection Process Linear Drainage Product Selection Procedure The following pages describe the procedure for choosing the most appropriate Marshalls linear drainage system for a particular application. Marshalls comprehensive range of drainage systems can be split into three categories; 1. Combined Kerb and Drainage systems specifically designed for kerbside use; Beany Block Mini Beany 2. Slot Drainage Systems designed primarily (though not exclusively) for non-kerbside use; Max-E-Channel Slot Drain Duo and Mono Traffic Drain Landscape Drain Decathlon 3. Grid Drainage Systems designed primarily (though not exclusively) for non-kerbside use; Birco The position of outfall, the area to be drained, topography and rainfall intensity will each affect the final decision as to which is the most appropriate system. However, there are two fundamental factors which, more than any other, determine which system is most appropriate; Location( i.e. kerbside or non-kerbside) Capacity High Beany Block* Combined Kerbside Kerb & Drainage Capacity Systems Medium Mini Beany* Linear Location Drainage Decathlon Max-E-Channel Birco 200 High Birco 300AS Non-kerbside/ Slot Drainage & Capacity Channel Grid Systems Birco Lite * Slot Drainage and Grid System can also be used in kerbside locations. Medium Birco 100 Where this is the case follow the design procedure for non-kerbside/ Birco 150 channel drainage Landscape Drain Traffic Drain Slot Drain Duo Slot Drain Mono Fig. 3 General Principles for Selecting the Appropriate System 9

10 Selection Process Channel Drainage Systems Five channel linear drainage systems are available from Marshalls, designed Step 4 primarily (though not exclusively) for non-kerbside applications; If the channel length is well in excess of 60m, refer to the Max-E-Channel Max-E-Channel High Capacity Linear Drainage System range page 59 and Birco 300 page 101. Choose either a large capacity system Birco Linear Drainage System with few outfalls or a medium capacity system with more outfalls Landscape Drain (See note 2). Slot Drain Traffic Drain Step 5 Decathlon Determine the load classification of the channel systems application and specify the appropriate grating or top unit (See note 3). Selection Procedure The choice of channel drainage system will often be determined by site In addition to the above, the following factors should also be parameters, such as size of area to be drained, existing levels and length of considered: drainage runs. The following steps should be followed to establish the most appropriate Marshalls channel. Location of Existing Main Drainage If the location of the existing drainage system is fixed, it will Step 1 determine outfall locations and optimum design of the linear Determine the location of the channel drainage system within the drainage system may not be possible drained area.

Summary of General Principles for Selecting an Appropriate Marshalls Channel System 10

11 Notes 1) Generally, where the linear drainage channel length is in the order This example shows typically two Birco Lite, 100 or Landscape Drain runs of 60m, one centrally located outfall will be sufficient and a medium utilising in-built fall channels, with four outfalls discharging into a carrier capacity system such as Birco Lite, Landscape Drain or Birco 100 can pipe system. This is a highly cost-effective solution and would result in be used. considerable savings compared to an alternative point drainage solution. Example 3) The loading classifications, as defined in BS EN 1433: 2002 Drainage A relatively small paved area of dimensions 50 x 50m can be easily channels for vehicular and pedestrian areas - classification, design and drained by a 100mm wide channel system such as Birco Lite, Landscape testing requirements, marking and quality control, are as follows; Drain or Birco 100. One centrally located outfall to suit the existing main drainage system will be sufficient. Class A15 Areas which can only be used by pedestrians and pedal cyclists 2) Where linear drainage channel runs are well in excess of 60m, say 200m, then there is a choice of 2 options; Class B125 Footways, pedestrian areas and compatible areas, private car parks or parking decks Option 1 - a high capacity system (Max-E-Channel or Birco 300) with few outfalls or, alternatively; Class C250 Kerbside and non-trafficked areas of hard shoulder that extend to a maximum of 0.5m into the trafficked area Option 2 - a medium capacity system (eg Birco 100) with multiple outfalls Class D400 Carriageways of roads, hard shoulders and parking areas Example for all vehicles For a paved area of dimensions 200 x 150m, then the options are as follows; Class E600 Areas subject to high wheel loads e.g. ports and docksides Option 1 Class F900 Areas subject to especially high wheel loads e.g. aircraft pavements Fig. 6 High Capacity System with Few Outfalls This example shows Marshalls Max-E-Channel, Decathlon or Birco 300AS draining the area with only one outfall at the end of the channel run. Less carrier pipes are used, resulting in even greater cost savings. There will also be less excavation with this design. Option 2 Fig.7 Medium Capacity System with Multiple Outfalls 11

12 Design Principles Introduction The Modified Rational Method The basis of hydraulic design of any linear drainage system is fundamentally The Modified Rational Method (often referred to as The Wallingford like any other engineering analysis; an assessment is made of the required Procedure) is considered more accurate for larger schemes with longer performance level that the element has to achieve and this is compared to drainage runs. Whilst the method generally assumes that the whole drained the elements ability to accommodate this. In the case of linear drainage, area contributes to the peak run-off, it uses typical storm profiles based upon how much water (peak run-off) will be flowing down the channel compared actual data and takes into account actual geographical rainfall variations. to the maximum stated flow capacity of the channel for the given conditions In this way, the critical rainfall intensity for a given set of parameters and without causing any problems such as flooding. conditions can be calculated. The only decision that a designer makes is to choose a storm return period. Again several factors will influence this There are therefore two elements to any linear drainage design; a choice but periods of between 1 in one year to 1 in two years are typical determination of the peak run-off or maximum flow along and out of the for designing the linear drainage systems for most applications with only channel and a determination of the systems maximum capacity. more onerous designs considering a 1 in five years return period. Reference can be made to BS EN 752 for advice on the choice of return period and Peak Run-Off the Modified Rational Method document advises time of entry for chosen The determination of peak run-off will depend upon many considerations return period. including; Size and location of the drained area Maximum System Capacity Use and application of the drained area Analysis of water flow along a linear drainage system where water Chosen or calculated rainfall intensity 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 Whilst several methods of calculating the peak storm water run-off exist, is uniform or steady as the flow in equates to the flow out and that as there are two which [Marshalls recommend] should be considered when the parameters along the system will generally remain unchanged, the designing linear drainage systems; flow is essentially unaltered. For these conditions, flow capacity has been The Simple Area Run-Off Method determined from traditional methods such as the Colebrook-White formulae. The Modified Rational Method (often referred to as The Wallingford Procedure) Where continuous lateral inflow is involved and particularly where large flows for large drained areas are concerned, a steady flow state may not be The Simple Area Run-Off Method achieved and an alternative to steady state flow capacity determination may In the Simple Area Run-Off Method, it is assumed that the whole of the need to be considered. 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 Recent research work carried out at HR Wallingford has considered this actually assumed. Therefore the assumed value for rainfall intensity is directly aspect of Marshalls linear drainage systems. The principle of spatially variable proportional to the peak run-off. A balance is often made between cost flow was established where, particularly for shallow gradients, the position and the level of performance required but it is generally accepted that this of peak depth and hence the critical location moves from the assumed method will yield conservative results. location at the outfall upstream towards the head of the run. The research The peak run-off formula used in this method is:- work confirmed that for Marshalls Beany Block system, where flow-capacities Q = A x i/3600, where have traditionally been calculated using Colebrook-White, for all practical Q is the peak storm water run-off (in litres per second) applications the capacities quoted were realistic and accurate. However, A is the drained area (in square metres) Colebrook-White gave very conservative figures for shallow gradients or flat i is the rainfall intensity (in millimetres per hour) applications and more cost-effective designs can be completed using data derived from the HR Wallingford work. The theory and practical application Some typical values assumed for rainfall intensity are given below. Engineers of flat channel flow is confirmed in TRL Report 602. and designers must choose carefully and give due consideration to the performance level required; Flow data contained in the Marshalls Drainage Design Guide are derived from 75mm/hr (0.021 l/m/s) Areas where the consequences of flooding are both HR Wallingford research and from traditional methods. Each systems serious such as where roof drainage [or entrances to buildings] is involved data will indicate its source. 50mm/hr (0.014 l/m/s) Car parks, pedestrian areas, roads or highways 40mm/hr (0.011 l/m/s) Service yards In addition to flow capacity figures, velocity data is also included. The velocity 30mm/hr (0.008 l/m/s) Large storage areas such as ports data has been determined by dividing the appropriate flow capacity by the full cross section area for the section under consideration. For Colebrook- In addition, this method of peak run-off determination should be limited to White derived flows, this is accurate; for HR Wallingford derived flows this is use when designing relatively small drained areas (less than 10,000m) and conservative. when designing relatively short runs of linear drainage (less than 200m). 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. 12

13 Other Considerations There are other aspects of linear drainage design beyond the factors given above. These include: Maintenance All surface water collection and transport systems will require maintenance to ensure efficient performance. Where linear drainage is designed for shallow gradients due care must be taken in the design for the effects of silting. Many systems are kept free from silting by the action of fast flow, but HR Wallingfords 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 varies, an equivalent uniform gradient may be derived from the HA advice note HA37. Specific advice on the application of this for Marshalls linear drainage or combined kerb and drainage systems is available upon request. Cross Falls and Drained Widths 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 designers control, and particularly where long drainage runs are being designed, the capacity of the outfall pipe work can sometimes limit the efficiency of the system. Capacity figures for Marshalls outfalls are given in the appropriate sections. These figures are based upon theoretical but conservative calculations. Details are available upon request. 13

14 Design Principles Drainage Arrangements Due to the manufacturing flexibility available to Marshalls, we are able Inbuilt fall Channels are available as follows: to offer several of our linear drainage and combined kerb and drainage systems with pre-sloped or inbuilt fall channels or base units. Channel Type Units Type Fall Per Set The inherent flexibility of inbuilt fall systems gives the designer a Birco Lite 0.5% 10 mm/1000 mm channel 20 no. Birco 100 1% 10 mm/1000 mm channel 20 no. number of options to increase the flow capacity of the drainage run as Birco 150 1% 10 mm/1000 mm channel 20 no. circumstances dictate: Birco 200 0.5% 5 mm/1000 mm channel 20 no. Landscape Drain 1% 10mm/1000 mm channel 20 no. Constant depth invert channels can be laid flat, or to a slope to Marshalls Slot Drain 1% 10 mm/1000 mm channel 20 no. increase the flow and discharge capacity (Figs. 8 & 9 opposite). Channels with progressively deeper inverts can be introduced towards the outfall end forming a stepped construction. Again the slope will increase flow and discharge capacity (Figs. 10 & 11 opposite). Channels with inbuilt falls can be used (Fig. 12 opposite). Inbuilt falls Landscape Drain, Slot Drain Duo, Slot Drain Mono 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 that pavement level is parallel to roof level To maintain a level pavement adjacent to internal flooring in warehouse areas Where insufficient fall is present, inbuilt fall Channels allow the creation of an artificial valley with either a gully at the centre or at each end of a drainage run (Figs. 13 & 14 opposite) 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. 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 (100 and 150), Landscape Drain and Marshalls Slot Drain systems, the increment is 10mm per metre long channel (1%). For Birco Lite and 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 every 5 linear metres (Fig. 16 opposite).

This tried, tested and proven system Service. provides a unique, flexible and cost-effective solution to highway drainage requirements. Mini Beany, Traffic Drain and Max-E-Channel further extend the use of this product. The System Beany Block consists of base units of standard channel section and top units of inverted channel section, with an elliptical aperture in the centre of one side face. When installed they form a combined kerb and surface water drainage system strong enough to withstand loadings imposed by both road and construction traffic. The system has excellent surface drainage efficiency which coupled with its large flow capacity, makes Beany Block superior to and much less expensive than conventional kerb and point drainage on many highway and non- highway schemes. Beany Block installation, mechanically handled 20

21 Cost Advantages Beany Block is ideal where specific problems would arise with conventional High Capacity Performance drainage methods for example: Beany Block is a high capacity system able to store storm water. Where limitations are placed on outfall capacities, Beany can help eliminate the need for storage reservoirs or balancing ponds. Where there is insufficient fall to the outfall point. Beany Block can be used in flat areas or steep gradients. Where, in flat areas, either numerous, closely spaced gullies or false falls would be required in the carriageway. Inlet apertures are 500mm apart, reducing running or fast flowing water on the carriageway and eliminating ponding. Where long gully connections would be needed. Where surface water drainage pipes would conflict with service mains Construction Savings and cables. The Beany System combines water interception and transportation in one system. This minimises or eliminates the need for carrier drains, gullies and Where ponding would occur at low points. manholes, reducing construction costs and saving time. Where traffic safety and control measures would be required when Simple two-part system straightforward to design and detail, reducing widening existing carriageway. design times and cost. Easy to set out and straightforward to install. Beany Block is likely to be more economical than conventional kerb/point The overall construction period can be reduced as carriageway materials drainage where carriageways have crossfall, few vehicular crossings or where may be laid in a continuous sequence.

Wider on the inside of the top block to prevent blockages, inclined at 45 degrees to prevent silting and also to allow inspection of and rodding access to the base unit inverts. Road and Vehicular Crossings The system has been specifically designed so that where base units and cover plates are used to carry flows under carriageways or vehicular crossings, a minimum of 150mm of road material can be laid above the units to prevent damage and reflective carriageway surface cracking. The base unit maintains line and level under road crossings helping to keep construction time and costs to a minimum. Beany to Cover Plates Beany Block is fully compatible with the Max-E-Channel system. This allows for easy transition of Beany Block to Max-E-Channel. Instances where the flow collected in a run of Beany needs to continue across a junction or entrance and where interception of surface run-off is still required is possible with the use of Max-E-Channel. The invert is maintained and the differential height of the Beany and Max- E-Channel system is specifically designed to allow continuity of pavement level. Beany to Max-E-Channel (cast iron with holes) Pedestrian Crossing The system has been designed to allow for the construction of pedestrian drop crossings. Flow can continue in base units and cover plate support the standard kerbs used at the crossing. The advantage of separate base and top blocks is that it is easy to retrofit pedestrian crossings in any length of Beany. Beany at pedestrian crossing point 22

Alternatively, the Units may be bedded on to a layer of cement mortar 10- The following method of installation is recommended. 40mm thick on a previously prepared concrete foundation. Sufficient M-Seal bituminous mastic jointing compound should be trowelled Excavation on to one or both end faces so that the joint will be well sealed when the next Sufficient material should be excavated to accommodate Top and Base Units, Unit is tamped into position. Surplus sealant shall be removed from the inner concrete bedding and haunching. Any soft spots or poorly compacted surface of the Units as work proceeds. formation should be made good. 18 litres of M-Seal should be sufficient for the following length of Beany Block: Where Base Units and Cover Plates are to be installed beneath new pavements, the pavements shall be completed to top of roadbase level for M-Seal Requirement flexible construction, or to top of sub-base level for rigid construction, before Base Type Coverage (m/18l) excavation for the Units commences. 205 90 295 70 Setting Out 365 55 Setting out pins should be accurately located, in accordance with the 630 35 Contract drawings, with a string line level with the top front corners of the Base Units. Line and level will depend on the kerb upstand. It may be Where cutting is necessary, one or two Units shall be cut so that no single advantageous to locate setting out pins to the rear of the Units to avoid Unit is less than 200mm in length. All cutting and trimming of the Units shall having to lift the Units over the string line. be carried out with a concrete saw or disc cutter. Cutting of Base Junctions or Outfall Units is not recommended. Plenty of setting out pins should be inserted where Beany Blocks are laid on horizontal curves (e.g. every 5m for radius of 30m) and the appropriate splay Units used for radii of 50m or less. Top Blocks The string line should be set to the level of the top corner of Units. Again, Note: starting at the Outfall, the Units should be set directly onto a liberal quantity of The theoretical maximum gap between adjacent Top Block corners stiff, cement mortar to completely fill the whole of the joint. Cement mortar when laid to horizontal curves is 4mm and is zero when the radius is: shall be Class M12 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, Type Of Block Radius For Zero Gap (M) the general alignment should be checked from all directions as each Block is laid. Any Unit deviating by more than 3mm in 3m from line and level shall be 50/20 30.0 made good by lifting and relaying. 19/11 14.0 10/8 8.7 The inside and outside of the joints between Base and Top Units should be 7/6 6.8 pointed and cleaned out with a brush or rag as work proceeds. Where cutting is necessary, one or two Units shall be cut so that no single In practice, gaps between Base Blocks are likely to be slightly greater due to Unit is less than 200mm in length. All cutting and trimming of the Units, other laying tolerances and application of vertical joint sealant. than cast iron or steel, shall be carried out with a concrete saw or disc cutter. The approximate number of Blocks required for a quarter circle (external radius) i.e. 90 road junction, may be calculated from: Cover Plates Top and Base 3.21 x R Cover Plates should be bedded on cement mortar to the specified thickness, Where R = horizontal radius (m) pointed inside and outside of the joints with the inside of the Base Units e.g. for Standard Top and Base Blocks laid to a 15m radius, being cleaned out as work proceeds. The Cover Plates should be close No. = 3.21 x 15 = 48 Units (24m) jointed and the joints sealed with 50mm wide M-Tape. Cover Plates shall be suitably protected before and during installation in order that the protective Base Units coating is not damaged. Base Units shall be laid to correspond to carriageway channel levels, or where Where cutting is necessary, one or two plates shall be cut so that no single beneath the carriageway, be laid to a straight grade. Starting at the Outfall, i.e. plate is less than 250mm. Cut or damaged plates shall be renovated in working uphill, the Units should be bedded on to a freshly mixed foundation accordance with BS 729: 1971 (1986). of the appropriate grade and thickness of concrete (refer to Standard Detail Sheet.). Concrete bed, haunch and surround shall be a standard mix complying with BS 8500-2: Beany Block Stop End Top Unit The Beany Block Stop End Top Units should be used at any transitions from Beany Block to half battered kerbs.

Example (i) D = Wearing Course + Base Course Surfacing Beany Block End Caps Where the Beany Block run does not terminate at an outfall, the base unit shall D = 100 be sealed using the Beany Block End Cap. This is available for Base 250, 295 d 50 and 365 and is formed of galvanised mild steel. The End Cap shall be securely placed against the vertical end of the base unit and haunched with fresh concrete. Mix ST4 Concrete Notes 1. In order to obtain a good line, it is very important to lay the Top Units Fig. 17 Base Block and Cover Plate Type A 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. Where the surfacing is less than 100mm or where Blocks are to be laid in an existing carriageway, additional drawings may be required showing vertical 2. It is not necessary for Top and Base Unit vertical joints to line up although staggers at the course interfaces so that the tops of the main trench sides are there will be more tolerance for adjustment of the Tops, if the joints are not less than 100mm from the final carriageway surface. These will vary with close together on curves of 10m radius or less. the number and thickness of each course as well as the total cover above the Units. 3. Where Beany Block is laid on or adjacent to existing or proposed concrete slabs, transverse joints shall be formed within the units and haunching Two typical examples are as shown in fig. 18 and 19. adjacent to the slab joints and also longitudinal movement joints between the haunching and the slabs. Where necessary, Top Unit drainage Example (ii) openings shall be protected against the ingress of material during concreting operations by covering with Waterproof Cloth Tape. D=85 4 . Outfalls, Silt Traps and Access Covers shall be constructed in accordance d 65 with the Standard Detail Sheet using the appropriate type of Base Unit. 75 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 Mix ST4 Concrete smooth 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. Fig. 18 Base Block and Cover Plate detail where D

41 9. Where flexible surfacing is laid greater than 15mm above the bottom of the drainage aperture, it shall be cut and shaped after rolling when partially cooled at each Top Unit, to form a smooth chamfer. A special steel cutting tool is available from Marshalls. 10. On completion of the works, the Beany Block 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. 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). 41

The levels should Installation of the Max-E-Channel Linear Drainage System should be carried be checked using the string line and a spirit level. In addition, the general out in accordance with the Specification and Standard Detail Sheets. The alignment should be checked from all directions as each unit is laid. Surplus following method of installation is recommended. mortar shall be removed from the units as work proceeds. Excavation Top Units shall be laid with the top of the unit 5mm below the final pavement Sufficient material should be excavated to accommodate Top and Base level. Units, concrete bedding and haunching, any soft spots or poorly compacted formation should be made good. The inside and outside of the joints between Base and Top Units should be pointed and cleaned out with a brush or rag as work proceeds. Setting Out Setting out pins should be accurately located, with a string line level with the Notes: top front corners of the Base Units. Pins can be located to the rear of the Units 1. In order to obtain a good line, it is very important to lay the Top Units on to avoid having to lift the Units over the string line. 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 Base Units sideways movement of the units to achieve an acceptable alignment. Starting at the Outfall, i.e. working uphill, the Units should be bedded on to a freshly mixed foundation of the appropriate grade and thickness of concrete 2. It is not necessary for Top and Base Unit vertical joints to line up. (refer to Standard Detail Sheet.). 3. Where Max-E-Channel is laid on or adjacent to existing or proposed Concrete bed, haunch and surround shall be: concrete slabs, transverse joints shall be formed within the units and i) A C20/25 concrete to BS 8500-1&2 and BS EN 206-1 for applications up haunching adjacent to the slab joints and also longitudinal movement to Load Classification C250 to BS EN 1433 joints between the haunching and the slabs. Where necessary, Top Unit drainage apertures shall be protected against the ingress of material ii) A C25/30 concrete to BS 8500-1&2 and BS EN 206-1 for applications up during concreting operations. to Load Classification F900 to BS EN 1433 iii) Reinforcement details for Base 630 application E600 and F900 ONLY are 4. Outfalls, Silt Traps and Access Covers shall be constructed in accordance as indicated 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 iv) A mix ST4 concrete to BS 8500-1&2 and BS EN 206-1 for Max-E-Channel Unit or vertical pipe, to make a watertight joint. Where necessary in-situ Trapped Gullies, Silt Traps, Catch Pits and outfall details concrete benching shall be shaped to the full depth of the Base unit. In v) The specification for carrier pipe concrete surround is by others Silt Traps, the pipe shall be bedded into mix ST4 concrete which shall be fully compacted to make a watertight seal. Alternatively, the Units may be bedded on to a layer of cement mortar 10- 40mm thick on a previously prepared concrete foundation. 5. In situ concrete haunching or surround should not be placed until the installed units have been inspected and approved by the Engineer. Sufficient M-Seal bituminous mastic jointing compound should be trowelled The haunching/surrounding should be carried out as one operation to on to one or both end faces so that the joint will be well sealed when the next complete lines of Top and Base Units in accordance with the Standard Unit is tamped into position. Surplus sealant shall be removed from the inner Detail Sheet. surface of the Units as work proceeds. 6. Adjacent carriageway and/or footway construction shall not be 18 litres of M-Seal should be sufficient for the following length of Max-E-Channel: commenced within 3 days of any jointing or haunching/surrounding concrete being placed. Base Units, Outfalls or Junctions not covered M-Seal Requirement by fully bedded Top Units or covers and frames, shall be adequately Base Type Coverage (m/18l) supported against loadings imposed by construction traffic. 205 90 295 70 7. On completion of the works, the Max-E-Channel System shall be cleaned 365 55 out by high pressure water jetting (100-150 bar at 200 l/min minimum) 630 35 and left free from obstructions and all Outfalls and Silt Traps shall be emptied. Top Unit drainage apertures shall be covered by timber boards Where cutting is necessary, one or two Units shall be cut so that no single or other approved method, during jetting operations. The cleaning Unit is less than 200mm in length. All cutting and trimming of the Units shall process shall be repeated where necessary after the completion of any be carried out with a concrete saw or disc cutter. Cutting of Base Junctions or remedial works. Outfall Units is not recommended. 8. Installation operations should be discontinued if weather conditions are At the termination of Max-E-Channel runs not located at outfalls, the base such that the performance of the Max-E-Channel may be jeopardised. units shall be closed using galvanised steel end caps as detailed in the Standard Detail Sheets.

The metre centres. following method of installation is recommended. Movement joints parallel to the Decathlon run should be formed either side Excavation of the channel to the full depth of the adjacent concrete slab. The joint should be designed to fully isolate the Decathlon system from any movement of the Sufficient material should be excavated to accommodate the channels, structural slab. Similarly, manholes and catch pits should be isolated from the top units or lids, concrete bedding and haunching. Any soft spots or poorly adjacent structural concrete slab by incorporating movement joints around the compacted formation should be made good. manhole or catch pit. Setting Out The design of the structural concrete slab with regard to the introduction of Setting out pins should be accurately located, with a string line level with the crack inducers, bay size and movement joint sealants is by others. top of the channel corners. Pins should be located to avoid having to lift the channel units over the string line. The top units must not be trafficked even by foot traffic until the concrete has had time to fully cure.
