compound earthwork drainage nets (BV cerificate)

Specifications

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

3D drainage net  

 

 

 

Specifications:

 

 

 

 1.a new drainage geosynthetics
  thickness
3.high tensile strength  

 

 

 

 

 

 Product Description:

 

 

 

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

 

 

 

 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.
