Self Adhesive Tanking Membrane 1 x 20m

Specifically designed for use as a waterproof membrane in critical areas such as internal and external tanking of underground structures, reservoirs, subways, lift shafts and retaining walls.

A high performance, self adhesive, flexible, waterproof membrane, manufactured from tough, cross-laminated HDPE film laminated to a 1.5mm thick layer of modified rubber / bitumen adhesive. The advanced carrier film gives improved tear strength, puncture resistance and impact resistance.
