Three-dimensional Drain Net
Specifications
It is widly used on the rubbish-landfills,high way subfrade and pavement,railwy,tunnel,gardon,playfrounds and other underground3D 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.
