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.

Features:
Net drainage geocomposites are manufactured using a unique geotextile filter developed specifically for use in drainage geocomposites for its high tensile modulus and ability to prevent soil ingress into the void space of the drainage core.
The drainage cores are manufactured from HDPE nets which have been engineered to have good flow under high loading.
