Product Introduction:
The concave convex hollow vertical reinforcement structure of waterproof and drainage protection boards can quickly and effectively discharge rainwater, greatly reducing or even eliminating the static water pressure of the waterproof layer. Through this active water guiding principle, active waterproofing can be achieved.
Waterproof performance: The waterproof and drainage protection board material itself is a very good waterproof material. By adopting a reliable connection method, the waterproof and drainage board becomes a good auxiliary waterproof material.
