A specialist three-ply sealing tape made from thin non-woven fleece and a flexible waterproofing membrane. Two outer layers of polypropylene fleece sandwich an inner polyurethane membrane, giving flexible waterproofing across expansion joints when applied with tiles or natural stone. It is suited to indoor applications carrying medium loads of non-pressurised water, such as domestic bathrooms. Each roll measures 5 m × 100 mm.
