3D composite drainage networks

Trdimension composite geonet for drainage is made of a unique trmension 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.

 Application

1)    Landfill drainage;

2)    roadbed and road drainage;

3)    railway drainage;

4)    tunnel drainage,

5)    underground structure drainage,

6)    the retaining back wall drainage;

7)    gardens and sports ground drainage

 Features

 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 2000kpa compression load

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

6) Certificate :ISO14001:2004, ISO9001:2008

   3D compound drainage net is a new drainage geosynthetics.3D drainage net consists of a three-dimensional viscous core geonet and a kind of non-woven geotextile which both sides have a needle prercing.

     The three-dimensional core geonet consists can quickly ground water discharge path,and it has a porous self-maintenance system that can block the capillary under high load of water.At the same time,it can also play the role of isolation and foundation strengthening.

 

Function:

 

It is widly used on the rubbish-landfills,high way subfrade and pavement,railwy,tunnel,gardon,playfrounds and other underground structures.
