3D composite drainage geonet
3D composite drainage geonet tri-dimension composite geonet for drainage is made of a unique tri-dimension geonet coated geotextile on both sides. It has the property of geotextile(filtration function) and geonet (drainage and protection) and remain the certain thickness. Provide good water conductivity.
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.
