Wallbarn Protecto-Drain 20 Drainage Membrane 20m x 2m Black

Protecto-drain 20 is a 1mm thick HDPE membrane ideal for large-scale tanking and sealing projects. Its 20mm larger cup size allows significant groundwater passage and is perfect for bridges, tunnels, and civil engineering applications. The flexible material is easy to install, handling substantial groundwater and drainage efficiently. The HDPE composition ensures no water pollution, allowing water to be managed and recycled for various uses. Protecto-drain 20 offers a cost-effective approach to subterranean water control, preventing hydrostatic pressure by redirecting water rather than stopping it. Its 'egg-box' profile avoids blockages and facilitates easy sealing, clipping sheets in place with overlapping cups and adhesive tape. In vertical applications, it serves as an effective waterproofing and protective layer between concrete layers.. Wallbarn Protecto-Drain 20 Drainage Membrane 20m x 2m Black
