Waterproof HDPE 3D Composite Drainage Geonet
HDPE 3D Composite Drainage Geonet
Product introduction
Tr-dimensiton composite geonet for drainage is made of a unique tri-dimension geonet adhibited geotextile on both sides. It has the property of geotextile (filtration function) and geonet (drainage and protection) and provide a function system "filtration-drainage-protection". The core of net with its unique tri-dimension structure can bear higher compressing load in construction and remaiin the certain thickness, provide good water conductivity.
