Waterproofing Membranes

Wetrooms UK use RIW Tilesafe and RIW FWM to waterproof the floors and walls in our wetroom installations.

RIW Tilesafe

RIW Tilesafe has been designed to be used prior to the application of tiles, (including natural stone and porcelain) onto solid and timber floors in wetrooms and other critical rooms that require waterproofing. RIW Tilesafe is a heavy duty, cold applied, self adhesive waterproof membrane, consisting of a thick rubberised waterproof layer with a woven glass fibre mesh on one side.

RIW Tilesafe provides wetrooms with a consistent waterproof layer that is guaranteed not to leak when installed effectively. Conventional tile adhesives can then be used, which will bond to the glass fibre mesh.

RIW Tilesafe also acts as a valuable de-coupling membrane, as it allows the floor tiles to uncouple and accommodate any movement across the floor substrate. The membrane will also improve the sound insulation value (∆Lw) of a typical wetroom floor assembly by 11dB, as it acts as an acoustic barrier.

Al of the tests were carried out in accordance with BS EN ISO 140-8, and the results (∆L) were rated in accordance with BS EN ISO 717-2.
