Drainage and venting layer for water and/ or gas.
Visqueen Geocomposite Drainage and Venting Mat is a UK manufactured preformed drainage and venting layer supplied in roll form. It comprises a cuspated HDPE (High Density Polyethylene) core bonded to a nonwoven polypropylene geotextile filter membrane. When laid the product forms a void to collect and transmit water and/ or gas into adjacent drainage outlets or collector pipes. Typical applications include drainage for externally applied tanking, drainage behind retaining walls and gas venting below ground bearing slabs. The product can be applied horizontally or vertically.
For installation and test results information please refer to the manufacturer's datasheet.
