Composite geonet for drainage:
1. Geonet Introduction
It is made of a unique tridimension geonet adhibited geotextile on both sides. It has the property of geotextile and geonet.
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.
2. Typical Applications of Geonet
Landfill drainage; roadbed and road drainage; railway drainage, tunnel drainage, underground structure drainge, the retaining back wall drainage, gardens and sports grounds drainage.
3. Features of Geonet
1). Excellent drainage function, can bear long time high press road
2). High tensile and shear strength
3). Reduce the rate that geotextile embedding into the core of geonet, can protect long time stable water conductivity
4). Can bear more than 2000KPa compression load
5). Its anti-compression capacity is much larger than common geonet for drainage.
