Tunnel Drainage Geosynthetic Fabric Composite Drainage Geonet 2 Meter Width
HUATAO Tri-dimension Composite Genet for Drainage is made of a unique tri-dimension geonet adhibited geotextile on both side. 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 remain the certain thickness, provide good water conductivity.
1. Landfill drainage
2. Roadbed and road drainage
3. Railway drainage
4. Tunnel drainage
5. Underground structure drainage
6. The retaining back wall drainage
7. Grdens and sports grounds drainage
1 - Excellent drainage function, can bear long time high press load.
2 - High tensile strength and shear strength.
3 - Reduce the rate geotextile embedding into the core of geonet, can protect long time stable water conductivity.
4 - Tri-dimension composite geonet for drainage can bear more than 2000 kpa compression load.
5 - Its anti-compression capacity is much larger than common geonet for drainage.
PROPERTY
Tri-dimension composite geonet for drainage is made of a unique tri-dimension geonet coated with geotextile on both sides. It has the property of geotextile(filtration) and geonet (drainage and protection) and provide a function system of“filtration-drainage-protection”. The tri-dimension structure can bear higher load in construction and remain certain thickness,strength and excellent in water conductivity.
