Siphon Drainage Board

Pump-like Positive Drainage System
Siphon drainage board has a concave convex hollow vertical reinforcement structure attached with geotextile. Utilizing the priciple of negative pressure differential, siphon structure can quickly and effectively drain rainwater without any energy, greatly reducing or even eliminating the hydrostatic water pressure of the waterproof layer. Through this active water guiding principle, the active waterproof effect can be achieved

Eco-friendly, Cost-effective and Energy-free
Replacing the cobblestone filter layer with draining sheet, siphone drainage board not only saves time and effort, but also saves energy and protect environment, reduces investment, and lowers the load on buildings

Excellent Durablilty and Protective Capacity
Siphon drainage board adopts good waterproof material. By using high-temperature hot melt welding connections, siphon drainage board becomes a good secondary waterproof material. Moreover, siphon drainage boards can effectively protect structures and waterproof layers, and resist various acids, alkalis, plant root thorns in the soil. When backfilling the exterior walls of basements, it can protect buildings and waterproof layers from damage.
