Description:
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.
Typical Application:
drainage in landfill; roadbed; railway,tunnel,underground structure,the retaining back wall, gardens and sports grounds.
Featuresï¼
Exnt drainage function, can bear long time hige press load
High tensile and shear strength
Reduce the rate geotextile embedding into the core of geonet, can protect long time stable water conductivity
Tri-dimension composite geonet for drainage can bear more than kpa compression load
Its anti-compression capacity is much larger than common geonet for drainage.
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 ofâfiltration-drainage-protectionâ. The tri-dimension structure can bear higher load in construction and remain certain thickness,strength and exnt in water conductivity.
