3d compound drainage net

It consists of a three-dimensional viscous core geonet and a kind of non-woven geotextile which both sides have a needle piercing. The three-dimensional core geonet consists can quickly groundwater 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. 3D complex drainage net used with geotextile,can reach the efficacy of inverted filter-drain-protect.Now It is the most perfact drain geosynthetics. Function: It is widly used on the rubbish-landfills,high way subfrade and pavement,railwy,tunnel,gardon,playfrounds and other underground structures.
