Description

Shelterseal Membranes are self-adhesive damp-proof membranes (DPMs) for basement retaining walls and floors. They are applied under floor slabs and foundations and to the exterior face of basement retaining walls to prevent water vapour penetrating to the interior face in spaces where moisture may cause damage.

The products are supplied as self-adhering, cold-applied, polymer-rubber modified bitumen sheets in roll form and are applied as single or double-layer systems.
