Reinforced Waterproof And Vapour-Proof Membrane
Estoproof 400 is a cold applied, self adhesive sheet waterproofing membrane consisting of a tough, damage resistant, polyester fabric reinforcement sandwiched between two layers of polymer modified bitumen.
It has a carrier film on the upper surface to assist in handling, and a peel off selvedge strip providing a bitumen to bitumen bond at the edge laps. The adhesive surface is protected by a release paper which is removed before application.
To provide a vapour and waterproof membrane in building and civil engineering structures.
To act as a barrier to the passage of vapour through ground slabs. It also protects concrete from attack by aggressive ground salts.
Typical applications include basements, ground slabs, reservoir roofs, foundations, lift pits and subways.
Substrate should be float finished and free form any contamination, cavities and projecting aggregates.
Apply Estoproof Primer W to the substrate and allowed to dry tack free, prior to the application of Estoproof 400.
The membrane should be applied to the substrate having first removed the silicone release paper, pressing the polyethylene film firmly ensuring that the adhesive bitumen compound bonds continuously to the substrate with no air pockets.
Allow a 50 – 75 mm overlap at the edges of the membrane and
100 – 150 mm overlap at the ends and press or roll the overlaps ensure a positive watertight bond.
All overlaps on vertical or inclined surfaces must be carried out to produce “Weathered Overlaps”.
Wall and floor slab junctions shall be laid with Angle Fillets to create a smooth transition.
The membrane should be protected immediately after application with Protection Board or cement/sand screed.
