ACO MultiDrain MD Introduction to ACO MultiDrain MD ACO MultiDrain MD benchmarks a new approach in the planning, delivery and installation of general purpose channel drainage systems. Designed to provide an effective solution for a wide variety of applications, ACO MultiDrain MD system maximises functionality whilst using the minimum number of components. What is ACO MultiDrain MD? ACO MultiDrain MD channel drainage system is manufactured from Vienite, ACO s sustainable high strength material. It is available in three widths; mm, 50mm and 00mm, and has a variety of depths and slopes. The channel units are certified to BS EN 433: 00 Load Class D 400* and form the main components of the system. Depending on the load class and application requirement, a wide range of gratings are available to complete the system. You can now chose from a range of traditional and discreet slot drainage gratings, solid covers and cross footpath drainage units to ensure all applications are catered for. All gratings within the system are fitted with ACO Drainlock, a barless locking device which reduces the risk of blockage and improves hydraulic capacity. The mechanism also provides for easy installation and maintenance of the system. As standard, channels are manufactured with UltraSTEEL protective edge rails. The UltraSTEEL rails, with their unique patented design, provide optimum channel protection and improved bonding between channel sides and the surrounding pavement material. 4 ACO MultiDrain MD System can provide a channel drainage solution for many applications by simply selecting the appropriate channel depth and grating type. Some of the applications that can be catered for are listed below. 4 Threshold drainage 4 Public landscaping 4 Car parking 4 Light industrial 4 HGV parking 4 Petrol station forecourts 4 SuDS Discreet slot drainage Apply the ACO Brickslot grating to the channel unit to form an unobtrusive drainage system. The offset grating can be used as a solution for threshold drainage and also against buildings eliminating difficult installations. The gratings are suitable for BS EN 433: 00 Load Class C 50 and D 400* applications. ACO Brickslot gratings are available for mm, 50mm and 00mm wide channels, in both galvanised or stainless steel. See page 3 for further details. Services ducts The ACO MultiDrain MD System includes a solid cover grating which when applied to the main channel unit provides a secure shallow trench with easy access to services and cabling. Cross footpath drainage Where roof drainage from down pipes is required to cross the footpath into the road gutter, a range of down pipes connectors, kerb outlets and shallow channels are available within the ACO MultiDrain MD System range. See page 36 for further details. This system is only available in the ACO MultiDrain MD System. Threshold drainage The ACO MultiDrain MD System can be used to provide unobtrusive drainage around building entrances, compliant with the building regulations (England and Wales Part M, Scotland Section 4, rthern Ireland Part R). Simply select the appropriate grating to meet your aesthetic requirements.

Why choose ACO MultiDrain MD? Made from sustainable materials ACO MultiDrain MD channel elements are manufactured from Vienite. Vienite is ACO s new high strength sustainable material that meets environmental and sustainability targets for construction products. Vienite utilises high levels of post consumer recycled waste, but unlike some recycled materials does not compromise on strength or long term performance. Vienite s high strength characteristics means the material is four times stronger than traditional concrete and has a low water absorption rate. It is also resistant to freeze thaw attack and has excellent chemical resistance. At the end of the products operational life, Vienite can be collected, processed and returned to production as a raw material. 5 System benefits 4 Provides an efficient drainage solution for a wide variety of applications 4 Range of constant, sloped and shallow depth channels 4 Caters for a range of catchment areas 4 Strong and robust channel design 4 Patented UltraSTEEL channel edge rail for improved strength and durability 4 CE Marked and BS EN 433: 00 certificated to Load Class D 400* 4 Extensive choice of gratings and accessories for many applications 4 Choice of outlet options, gullies, sumps or channel knockouts 4 Unique ACO Drainlock grating fixing improves hydraulic capacity 4 Lightweight design is simple and fast to install 4 % recyclable 4 Ideal for use against building facades or as a Part M threshold drainage solution when used with ACO MultiDrain Brickslot grating * t suitable for carriageways of public roads or motorways.

Problem solving drainage solutions: Discreet slot drainage ACO MULTIDRAIN MD BRICKSLOT Galvanised steel ACO MultiDrain MD has a range of gratings to complement installations which require discreet slot drainage. Designed as standard with a heelguard 0mm off set drainage inlet, ACO Brickslot is a subtle and unobtrusive grating which when combined with an ACO MultiDrain MD channel, can be used as a solution to complement discreet drainage applications and is ideal for use against buildings facades. Compatible with most paving materials, the vertical sides of the grating enable pavements to be laid directly to the unit s edge. Once installed the system is totally secure and not vulnerable to vandalism or loose grates making it a suitable for applications such as schools and playgrounds where grating removal can become a hazard. The channel and ACO Brickslot grating together provide an unobtrusive continuous slot drainage system, with high hydraulic efficiency for fast removal of surface water. ACO Brickslot gratings are available in galvanised or stainless steel and suitable for use with the mm, 50mm and 00mm wide channels in the ACO MultiDrain MD range. The system includes an ACO Brickslot access unit to ensure easy maintenance and access to the drainage system, and is also fully compatible with the range of ACO MultiDrain MD accessories. The system is suitable for applications up to and including Load Class D400 (This product is not suitable for carriageways of public roads or motorways).

Channel footpath drainage CHANNEL FOOTPATH DRAINAGE Specifically for use where roof drainage from down pipes is required to cross the footpath into the road gutter, ACO MultiDrain MD/MDS systems has a range of accessories to construct a footpath drainage system. This system is suitable for Load Class D 400 applications Load class

The ACO MultiDrain MD/MDS system includes a range of accessories which provide a drainage solution ideal for areas where down pipes from roofs and gutters exit on to the pavement. The ACO Channel Footpath drainage system effectively carries water away from paved areas and across into the adjacent carriageway. The system uses ACO MultiDrain MD/MDS shallow depth channels and has two types of kerb outlets and down pipe connectors to suit application requirements. Shallow channels ACO MultiDrain MD shallow depth channels are available in two sizes, 75mm and mm total depths (ACO MD / MDS 075 and ACO MD / MDS 0) and have the option of galvanised or stainless steel edge rails. Downpipe connectors Two down pipe connectors are available to suit channel depth. Manufactured from grey polymer concrete the down pipe connector has a clear opening of Ø75mm and connects to down pipes with outside diameters of up to 8mm. Kerb outlets Two outlets are available to suit the kerb profile of the application, a CFD half battered kerb outlet to suit standard HB kerbs and a CFD Bull nose kerb outlet to match BN kerbs. Manufactured from grey polymer concrete the kerb outlets allow rainwater to discharge into the road gutter from this system. Gratings Traditionally solid ductile iron covers are selected in channel footpath drainage applications but all ACO MultiDrain MD/MDS gratings are suitable for use with this system. The system s load class rating is determined by the grating selected, further information of gratings within the range can be found on pages 48. 3406DL Ductile iron solid cover Channel footpath drainage ACO MultiDrain MD shallow depth channels with UltraSTEEL galvanised edge rails 3075 MD. 075 0 overall 75 55 9. 3076 MD. 075V 0 75* 55 8.85 30 MD. 0 0 80 3 MD. 0V 0 * 80 ACO MultiDrain MDS shallow depth channels with stainless steel edge rails 4075 MDS. 075 0 overall 75 55 0.9 37 4076 MDS. 075V 0 75* 55 0.55 40 MDS. 0 0 80.7 4 MDS. 0V 0 * 80.4 mm 0mm mm mm 0mm mm 5580mm MD/MDS 0750 channel 75mm 5580mm Ø0mm mm 8005mm MD/MDS 075V 0V channel te: V Indicates channel with cast in triple lipped seals for water tight connection.

Preparing the system for installation Channel base knockout details All ACO MultiDrain MD constant depth channels in the height range 0.0 to 30.0 are supplied with a pre formed knockout detail in the base of the channels. This knockout detail positioned at the male end of the channel allows a vertical connection to be made from the channel to a Ø0mm (mm wide bore) or Ø60mm (50mm and 00mm wide bore) PVCU pipe system. The knockout detail on the base of the channel is indicated by a "hammer" symbol. The method of removal and pipe connection is described below. Channel side wall connection detail An additional feature provided on all mm long channels are removable side wall panels, which allow channel runs to be connected together to form "T" or "L" junctions for continuous water flow through the system. Where channel connections are to be made to the side wall of these units a female joint detail is provided to aid alignment and fast installation. Shallow Channels The ACO MultiDrain MD shallow channels are available in either 75mm or mm overall depths. These units are idea for use where installation depths are restricted such in structural slabs, bridge decks and roofs. All units can sealed for watertight installations as each unit is supplied with a preformed sealant groove (see section headed watertight sealing for further details). The shallow channels identified with a V such as the 075V and 0V units have a castin triple lipped seal in their base for push fit watertight connections to Ø0mm PVCU pipe. These triple lipped seals are manufactured from SEBSTPE have excellent chemical, UV and weather resistance. Removable side wall panel. Knockout detail. FUNCTIONS: FUNCTIONS: FUNCTIONS: Step : Pre formed knockout detail Step : Using a disc cutter as shown, cut a cross into the panel provided. Ensure cuts extend to but not beyond the perimeter recess surrounding the removable panel. Step : Ensure Triple lipped seal and pipe spigot are clean and free from debris. 39 Step : Support channel around knockout detail by placing the channel on sand or soft earth for example. Tap the knockout panel from the side indicated by the Hammer symbol to remove panel. Step 3: Push fit pipe into recess provided and seal as required. For recommended sealants refer to the section headed "watertight sealing". Step : Tap segments of panel between the cuts to remove the panel. Step 3: Use a chisel to tidy up any remaining material. Channel connection can now be made and sealed as required. Step : Lubricate joint faces as required and push fit pipe into the seal. The pipe is fully fitted when the end of the pipe is flush with the internal base of the channel.

ACO MultiDrain MD Step connector Watertight sealing Multifunctional endcap Each width of MultiDrain MD has available a step connector manufactured from polymer concrete. This unit is used between constant depth channel joints where a stepped fall channel installation is required and takes up the 50mm height difference between units. The step connector ensures a smooth water flow within the channel system. ACO MultiDrain MD channels are generally installed without a particular water seal. Once butt jointed and with a concrete surround a fairly watertight installation is achieved. If however a water tight system is required each MultiDrain MD channel is provided with a sealant groove allowing the system to be sealed by the application of a flexible sealant either during or following installation. For rainwater applications we recommend a single component, polyurethane based elastomeric joint sealant such as BASF Masterflex 47 or Sika Sikaflex FC or similar. Application of sealant to be in accordance with the sealant manufacturers recommendations, but for guidance a typical method of application is as follows. A Multifunctional endcap is provided for each channel width that is designed to be used with all channel heights in each range. Manufactured from polypropylene these versatile endcaps can be adjusted on site to perform the function of a closing endcap or as an inlet/outlet endcap for connection to Ø0mm (mm wide bore) or Ø60mm (50mm and 00mm wide bore) PVCU pipe. Cutting guide Removable knockout panel FUNCTIONS: FUNCTIONS: FUNCTIONS: 40 Step : Place step connector into the base of the deeper channel to be jointed as shown. Step : Push channel joint together to lock step connector in place forming a smooth transition between units as shown. Step : Jointing faces of the channels to be sound and cleaned to remove all loose material, dust, oil and grease. This can be done by the use of a wire brush. Step : Butt joint the channels & install as per ACO installation instructions. Ensuring joints are still clean (surfaces can be damp but no water droplets should be evident) apply sealant with a cartridge gun approximately 5mm thick to the end face of the channel & completely fill the sealant groove. te this type of channel can be sealed either at or following installation. Step 3: Wipe excess sealant from the inside faces of the channel & inspect sealant groove to ensure it has been fully filled with sealant. Leave sealant to cure before use as per the sealant manufactures recommendations. Closing endcap: The endcap supplied fits directly to the deepest channel within the system. All other channel heights can be accommodated by simply cutting the endcap to suit. A cutting guide is printed on the front of the endcap plate. The endcap is fastened to the channel by two clips and can be connected to either male or female channel end. Adjusting endcap. Fitting endcap to channel Inlet & Outlet endcap: The endcap has a knockout panel which can be removed with a hammer. Once fitted to the channel the endcap performs either an inlet or outlet function and is designed to provide a connection to Ø0mm (mm wide bore) or Ø60mm (50mm and 00mm wide bore) PVCU pipes.

ACO MultiDrain MD Design method ACO MultiDrain MD channels are available in three widths (mm, 50mm and 00mm) and each width is available in several depths of constant invert channel. The channels can be in runs of constant invert depth (Type ) or in a stepped series of invert depths (Type 3). The mm wide MD channel is also available with a presloped invert to form channel runs of 0.5% invert slope at up to 0m length (Type ). The run lengths of presloped invert can be extended by lengths of constant invert channel. The channels may be laid with the gratings level. If there is some longitudinal fall, then the hydraulic capacity will be increased, allowing greater spacing between outfalls. DESIGN EXAMPLE The hydraulic capacity of channels accepting lateral inflow all along their length can be calculated by the analysis of the differential equations for spatially varied flow, a procedure that requires a computer program such as the proprietary ACO Hydro software or ACO s new online design software. ACO Design enables users to develop an optimised design of stepped sizes of channels, increasing in size down the run of the channel. For more information visit www.aco.co.uk For detailed designs using Hydro, please contact the ACO Water Management Design Services team. The team may also be consulted for advice where the inflow is not uniformly distributed along the channel and for channels with presloped inverts. The tables on the following page have been produced from the ACO Hydro software to facilitate a quick manual design method for the determination of the drainage requirements. The columns of drainage catchment area (A m ) are based on a rainfall intensity of 50mm/h, but can be adapted for use at any rainfall intensity. The columns of maximum flow rate (Q l/s) and maximum lateral inflow (q l/s/m) can be used at any rainfall intensity. The table of sloping invert channel capacities can be used for the design of MD sloping invert channels. ACO Water Management Design Services Team Tel: 046 86666 Email: technical@aco.co.uk i = 50mm/h D = 34m L =45m For a design of MultiDrain MD, assume the following figures: D = 34m (depth of catchment area) L = 45m (length of channel run = length of catchment) i = 50mm/h (design rainfall intensity) Ground slope = 0% te that any other rainfall intensity may be used. Typical intensities (from BS EN 75) are 50mm/h for areas where some ponding could be tolerated for a few minutes after heavy rainfall, or 75mm/h where ponding cannot normally be tolerated.. Determine the area 3. Determine lateral inflow (q) q = Q / L =.3 / 45 = 0.473 l/s/m Option Area = L x D = 45 x 34 = 530m 4 For a quick analysis, see the tables and the columns for Area. 530m is too large for one 45m run of ACO MultiDrain MD Try 530 x / = 765m L x / = 3m Estimating between the rows for 0m and 30m lengths One 3m run of ACO MultiDrain MD 0.0 can drain approx 800m Hence two runs can drain the 530m Or for a more detailed analysis, determine the total flow rate, as follows 4. Determine suitable channel sizes and lengths For example, would a sump at /3 length work with a lateral inflow of 0.473 l/s/m? /3 L = 5m, ACO MultiDrain MD 0.0 will be adequate /3 L = 30m, ACO MultiDrain MD 30.0 will be adequate 5. Check Outlet capacity Ensure that the proposed outlet has sufficient hydraulic capacity by reference to the product technical pages. Option Option 3 45m MD 0.0 sumps 45m MD 0.0 sump. Determine total flow (Q) Q = (Area x i) / 3600 = (530 x 50) / 3600 =.3 l/s 6. Solutions Three options are sketched (right).

Engineering advice may be required. 3.0 Surface Cracks: Alternate crack control and movement joints traversely within bed and haunch may reduce unsightly surface cracking. Engineering advice may be required. 4.0 Joint Sealant: Where ACO channel joints and fittings are to be sealed (where used in foul water applications or where impermeability is required, for example) contacting a sealant specialist for guidance on the most appropriate sealing compound to use. 5.0 Surface Protection: In asphalt pavements avoid contact between compaction equipment and channel/grating. This may be achieved by ensuring that the finished surface level lies above the grating level (by at least 3mm). Stones should be removed from grating prior to laying/rolling wearing course. 6.0 General Installation tes: See ACO drawing EE0003 for general notes on installation.

ACO MultiDrain MD 50 Chemical resistance chart Vienite, ACO s sustainable high strength material, has a high resistance to dilute acids and alkalis, and are unaffected by road salt, fuel and oil, and other commonly encountered chemicals. Further details of the chemical resistance can be obtained from the ACO Water Management Design Services team or, for particular chemicals, samples of the polymer concrete can be supplied to customers for their own testing. The chemical resistance will also depend on the temperature of the effluent. Clean water should not exceed 80ºC. The resistance of the gratings and edge rails should also be considered, and stainless steel gratings and edge rails are available in the ACO MultiDrain MD system for aesthetically pleasing installations and for specific chemical resistance. This chemical resistance chart refers to chemicals at ambient temperatures (0ºC) and the results are for general guidance only.

Typically, cast iron materials contain 40% to 90 % recycled iron, and steel products contain 5% to 33% recycled steel. The total recycled content of each product in the ACO MultiDrain MD system will vary as the proportion of the different materials (in channels, edge rails, gratings etc) varies. As an example, ACO MultiDrain MD channels with Heelguard ductile iron gratings will contain approximately 7% by weight recycled material. The ACO MultiDrain MD products are themselves intended for a long life with low maintenance, to reduce the need to recycle, but when eventually they are no longer needed, much of their content can be readily recycled with a very low risk of pollution to the environment. NBS Specifications ACO MultiDrain MD should be specified in section Q0:80. Assistance in completing this clause can be found in the ACO Water Management entry in NBS Plus, or please contact the ACO Water Management Design Services Team. te: A specification in NBS format is available to download from www.thenbs.com or www.aco.co.uk EU Conformity The ACO MultiDrain MD System is fully certified to BS EN 433:00 and CE marked in accordance with the Construction Products Regulation.
