Protecto-drain is a range of protection and drainage membranes made from high density polyethylene (HDPE) or polypropylene. Protecto-drain is used for landfills, protection of foundation walls, subterranean drainage, resistance to rising damp, soil stabilisation and green roof applications.

These tough, flexible membranes are manufactured with a cupped profile, which increases the strength and drainage capability of the material.

Wallbarn offers a number of different types of Protecto-drain, with different thicknesses, cup size and coverings, depending on the type of application. Please click onto the links below for more details:
