Manage high volumes of subterranean water with Wallbarn Protecto-Drain 20, a heavy-duty 1mm thick HDPE membrane designed for large-scale tanking, sealing and drainage applications. Its 20mm cupped profile creates a generous drainage space, allowing greater quantities of groundwater to flow along the membrane while helping prevent hydrostatic pressure from building against the structure.
Ideal for bridges, tunnels and civil engineering projects, Protecto-Drain 20 is flexible, easy to handle and straightforward to join. The egg-box profile allows overlapping sheets to clip together before the joints are sealed with adhesive tape, helping create a continuous installation. Its HDPE construction will not contaminate water, allowing collected runoff to be safely managed or recycled.
