|Core construction and character||
ABG Pozidrain, the original wide-width preformed drainage and gas venting geocomposite, offers a sustainable, environmental alternative to traditional filter stone.
Pozidrain consists of a high strength flexible polyethylene cuspated core with a non-woven geotextile bonded onto one or either side. The geotextile filters a wide range of materials; whilst allowing free passage of fluids into the core of the geocomposite to be drained to a discharge.
The HDPE core acts as a drainage medium with the channels between the dimples designed to support the geotextile which is bonded to the core to ensure that it doesn’t deform into the drainage passage under the pressure of the fill material. The core design allows flow in all directions unlike in pipes.
Compared with mineral drainage layers Pozidrain drainage geocomposites are much thinner whilst offering superior flow capacity. This reduces the required thickness of the capping and base lining system resulting in more fill void.
Pozidrain geocomposites are suited for rapid installation on large landfill and restoration projects and can be used for:
