Aggregate Industries Offers One Stop Shop For SUDS
7 March 2005, News release from Aggregate Industries plc
Aggregate Industries has developed a comprehensive range of source control sustainable drainage systems (SUDS) to assist the safe management of surface water.
The problems associated with the failure of conventional surface water drainage systems have been well researched and documented providing an increased awareness of the damaging environmental impact of major flooding and pollution incidents. The use of Sustainable Drainage Systems (SUDS) is recognised as an effective way to reduce this risk, with developers and local authorities being actively encouraged to adopt SUDS solutions by central and local Government, the Scottish Environmental Protection Agency (SEPA) and the Environment Agency (EA).
In compliance with the guidelines, Aggregate Industries has developed a comprehensive range of independently validated SUDS solutions to satisfy the requirements of relevant environmental authorities, from design and supply through to installation.
Within any system, a key element is the provision of water storage prior to controlled runoff and the company's SUDS range offers a choice of options to suit specific ground and site conditions.
Unique in the market, Charcon PermavoidTM is a high-strength, highly-voided sub-base replacement system. Any number of Charcon PermavoidTM boxes can be linked together to form the crucial water retaining layer, or reservoir, within a SUDS pavement, and the relatively shallow depth required for installation has the added benefit of reducing the cost of waste aggregate disposal.
Charcon Permavoid can be used in all applications where a traditional aggregate sub-base can be used. With specialist membranes and textiles the system will provide either an attenuation or infiltration drainage system.
Aggregate Industries also offers a 'no fines' granular material sub-base under license from Formpave who pioneered the system in conjunction with Coventry University.
Once the method of storage capacity within the system has been chosen a number of other design choices can be made. The first of these is the type of surfacing material used to allow infiltration into the storage system, most commonly concrete block paving.
Charcon Infilta is a rectangular block paving system, incorporating a 5mm spacer design. Each interlocking unit with its specially designed nib structure provides a 5mm void, allowing ingress of water through to the storage system. Available in red, brindle, charcoal and natural grey, Charcon's Infilta block paving offers all the aesthetic, strength and performance properties of Charcon's established range, with the added benefit of sustainable drainage.
Alternatively, conventional impermeable asphalt can be used causing the water to run into Charcon's PermakerbTM or Charcon PermachannelTM concrete products, which then disperse into a Charcon Permavoid™ storage system.
All Charcon PermavoidTM systems require at least one layer of an appropriate geotextile to prevent the bedding layer contaminating the storage area. A geomembrane is also needed for attenuation designs to create a watertight structure and to minimise the risk of subgrade softening - a full range of geotextiles and geomembranes are also available from Charcon.
