Three-dimensional composite drainage network is a new drainage geotextile material. High density polyethylene (HDPE) as raw material, processed by a special extrusion process is made with a special three-layer structure. Intermediate rib rigidity, longitudinally arranged to form a drain passage, the vertical arrangement of the cross ribs form a support to prevent the geotextile embedding drain passage, even at very high loads can maintain a high drainage performance. Double-sided adhesive seepage geotextile composite use, with "filtration - Drainage - Breathable - Protection" overall performance is the best drainage material is mainly used for railways, highways, tunnels, municipal engineering, reservoir, slope protection, etc. Drainage Project results are obvious.
