Concave convex drainage board
Concave convex drainage board
1.drain rainwater quickly and effectively
2. reduce or even eliminate the static pressure of waterproof layer
Concave convex drainage board
Concave and convex plastic drainage plate which the structure is concave and convex hollow reinforcement.Concave convex drainage board can drain rainwater quickly and effectively, greatly reduce or even eliminate the static pressure of waterproof layer, through this active water guide principle can achieve the effect of active waterproof.
Concave convex drainage board is a good waterproof material, which can effectively protect the structure and waterproof layer, and resist all kinds of acid and alkali in the soil and plant root thorns. When backfilling the basement wall, Concave convex drainage board can protect the building and the waterproof layer from damage.
