Tri-dimension composite genet for drainage is a new type of geosynthetics.Its made of atri-dimension geonet coated with geotextile on both sides. Network core consists of a tri-dimension thick vertical rib, and a rip on top and bottom .It can drain underground water quickly, also there is a protection system,which can block the capillary water under high load. At the same time, it can also reinforce and isolate of foundation. Specifications: core thickness: 5 mm - 8 mm; width 2 - 4m, composite geotextile: short fiber needle punched geotextile, filament spunbonded needle punched geotextile, the length at request. Properties: 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. Application: drainage in landfill; roadbed; railway,tunnel,underground structure,the retaining back wall, gardens and sports grounds.
