Protecto-drain 20 is a 1mm thick HDPE membrane which is useful for larger scale areas of tanking and sealing. It has a larger cup size of 20mm which allows a greater amount of ground water to pass along the membrane.
It is ideal as a lining membrane on bridges and tunnels, and a whole manner of civil engineering works. The flexible and easy-to-bond nature of the material makes it easy to install, and it can cope with larger quantities of ground water and drainage quite easily. The HDPE material will not pollute the water running off in any way, which means that water can be directed, managed and recycled for a whole manner of uses.
Protecto-drain 20 offers a much simpler, but often more effective way to manage and control subterranean water than many expensive systems and concepts. By sticking to simple principles of not stopping water but redirecting it, hydrostatic pressure points are prevented. By designing an “egg-box” profile, blockages are prevented and a greater amount of water can pass along the membrane. This profile also allows very easy sealing of the membrane, as multiple sheets can be “clipped into place” by overlapping the cups and sealing the joints with adhesive tape. In vertical applications it is very good as a waterproofing and protection layer between layers of concrete.
