Tri-dimension composite geonet for drainage is made of a unique tri-dimension geonet adhibited geotextile on both sides. 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 con-struction and remain the certain thickness, provide good water conductivity.
Typical Applications
Landfill drainage; roadbed and road drainage; railway drainage, tunnel drainage, underground structure drainage, the retaining back wall drainage, gardens and sports grounds drainage.
Three-dimensional network of drainage features:
Excellent drainage function, can bear long time high press load;
High tensile and shear strength;
Reduce the rate geotextile embedding into the core of geonet,can protect longtime 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.
