three dimensional geonet for dewatering

three dimension drainage net

150/2-1600/2 3Dcomposite drainage networks

Trdimension composite geonet for drainage is made of a unique tr-mension 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 tr-dimension structure can bear higher compressing load in construction and remain the certain thickness,provide good water conductivity.

Landfill drainage;roadbed and road drainage;railway drainage;tunnel drainage,underground

structure drainage,the retaining back wall drainage;gardens and sports ground drainage

1)Excellent drainage function, can bear long time hige press load

2)High tensile and shear strength

3)Reduce the rate 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 kpa compression load

5)Its anti-compression capacity is much larger than common geonet for drainage
