Zhonglong Triaxial Composite Geonet Drain is a geosynthetic product made by bonding a geonet drain core to one or two layers of geotextile using a thermal bonding process. The core is made of high-density polyethylene (HDPE) used to collect and convey water or gas. The geotextile layers act as filter, keeping small particles out of the drainage channels while allowing water to pass through.
Composite geonet drain can replace gravel or sand drainage layers (approximate 1m thick) and be used for landfill leachate collection, roadway subgrade drainage, retaining wall drainage, tunnel waterproofing and green roof systems.
Raw Materials: HDPE (Net Core) + PP/PET (Geotextiles)
Packing Method: Bagged Rolls
