1. Product Description
WATER-STOP is a thin load bearing, bonded, sheet membrane for waterproofing applications.
Installed using an appropriate thin-set mortar and with the W-S waterproofing accessories; bands, tapes,
corners and collars, is a complete assembly bonding together to create a watertight layer to protect the
structure and the tile installation from moisture and minor substrate cracking.
1.1. Material Working Properties
WATER-STOP is a highly-flexible polyolefin sheet membrane 0.02” (0.5mm) thick.
It is formed from several layers: the central sheet is made of two layers of EVA Copolymer film and
covered on both sides with a non-woven polyester/polypropylene webbing to anchor the membrane
into the thin-set mortar.
WATER-STOP meets the American National Standard for Thin-Set Ceramic Tile and Dimension Stone
Installations ANSI A118.10 for Load Bearing, Bonded, Waterproof Membranes and ANSI A118.12 for
Crack Isolation Membranes.
WATER-STOP has been independently tested and found to emit zero VOCs.
