Pondage and Drainage plate is through professional mechanical structure design, it has convex platform wall thickness, and accompanied by rein- forcement structure, high compressive strength, good flexibility, good drainage prevent not degrade.After through hot melt welding, resistance of plant puncture, acid and alkali resistance, ageing resistance, and it is for buildling waterproof formation of flexible protection, making whole waterproof layer en- closed space inside in the long run, not easy ageing. Greatly extending the waterproof layer of using fixed number of year.

Pondage and Drainage board has the special structure, which can quickly and effectively derived rain and greatly redace or even climinate the water- proof layer of hydrostatic pressure,also can achieve active waterproof effect through this initiative guide water principle

Pondage and Drainage plate material itself is a kind of very good waterproof materials. By using reliable down slope of overlapped method, it is to become a kind of very good auxiliary waterproof material. Pondage and Drainage plate can effectively redluce the indoor noise. Drainage shielding panels have very good ventilation moistureproof effect to use on the ground or metope.
