ABG Deckdrain is used in civil engineering and construction drainage applications; including bridge abutments, buried structures, retaining walls, tunnels, roof gardens and covered potable water reservoirs. ABG Deckdrain geocomposite consists of a high strength, flexible polyethylene cuspated core with a non-woven filter geotextile bonded onto one or both sides. The geotextile filters a wide range of materials whilst allowing water to percolate into the core of the geocomposite before draining to a discharge point.
The HDPE cuspated core of the geocomposite provides a free flowing drainage void. The cusps are designed to support the geotextile which is bonded to the core, to ensure that it doesn’t deform into the drainage void under the pressure of the backfill material. ABG Deckdrain is designed to allow flow in all directions, unlike linear or pipe systems.
ABG Deckdrain is durable and sufficiently robust to resist the mechanical stresses imposed during installation and then on throughout its design life. Use of ABG Deckdrain eliminates the need for further protection of the waterproofing system. ABG Deckdrain has been creep tested at compressive loads of up to 1,000kPa to give a design life of 120 years.
ABG Deckdrain is a UK manufactured BBA certified product, with a long history of use on National Highways, Transport Scotland and other major Highways schemes. ABG Deckdrain is available in a range of flow capacities from 1 l/m/s to 95 l/m/s, corresponding to thicknesses ranging from 4mm to 50mm, and can be supplied in a variety of roll sizes designed to suit differing site requirements.
ABG Deckdrain geocomposite is used in the construction of green bridges and green tunnels to protect the waterproofing and provide drainage to the structure, which removes the need for bulky porous blocks and the logistical challenge of importing granular fill.
