Cavidrain

Cavidrain consists of a single cuspated HDPE (High Density Polyethylene) core. The function of the product is to provide an external drainage layer between underground construction and the ground itself. Alternatively, it may be used as robust drainage layer to collect seepage between a porous or leaking wall, tunnel lining or floor slab and a new render, floor screed or slab.

The core is cuspated to form a network of drainage channels which allow seepage water to flow on the rear side safely away to outlets.​
