Product Description

3D Drainage Composite geonet for sewage treatment

Product Description
Composite Drainage Network is a new type of dewatering geotechnical material, which the raw material is HDPE and manufactured via particular extrusion forming technique. It has three levels, the inner fillet has strong rigidity, arrange longitudinal to form dewatering channel, the upper and bottom fillet form support to avoid geotextile inserting into dewatering channel, that means even if under high load it can also keep good dewatering property. It is the best dewatering material currently who has below function:” filter — dewatering — ventilate — protect”.


1,Excellent drainage function, can bear long time high press load.
2,High tensile and shear strength.
3,Reduce the rete 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 20Kpa compression load.
5,Its anti-compression capacity is much larger than common geonet for drainage

Tri-dimension composite geonet for drainage 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 compression load in construction and remain the certain thickness, provide good water conductivity.

1 Landfill drainage,
2 roadbed and road drainage
3 railway and tunnel drainage
4 underground drainage
5 retaining back wall drainage
6 Gardens and sports grounds drainage
