mainly used for seepage control, strengthening, protection of dams,, inverted filter, drainage
3 D compound drainage network is a new type of drainage geotextile materials, with high density polyethylene (HDPE) as raw material, the special extrusion processing technology from, with three layers of special structure.
The middle rib has a high tensile, vertical arrangement, ,it is the straight line drainage channels in the drainage formed, both sides were cross arrangement, increase the overall stability of the drainage network.
3 D drainage nets compound with geotextile, as a 3 D compound drainage nets, made up of the complete "inverted filter-drainage-protection" effect. It is the most ideal large area of drainage geotextile materials.
1. Drainage ability is strong, can be used and replace sand pad;
2. A long-term under great pressure load (can withstand more than 2000 Kpa compression load);
3. Reduce the probability of geotextiles into embedded core, can maintain long-term and stable conducting water rate;
4. Corrosion resistance, acid and alkali resistant, with long life.
5. Construction is convenient, shorten the construction period, lower cost.
