The USG Durock™ Brand Waterproofing Membrane is an innovative membrane that features an oriented HDPE, cross-laminated core that provides strength and tear resistance at much thinner mil thicknesses (12 mil), making it the most pliable, user-friendly membrane in the industry, with the least amount of buildup at seams.

The USG Durock™ Waterproofing Membrane is one of the strongest, most tear-resistant membranes on the market. And since it has the lowest perm rating of any load-bearing, bonded waterproofing membrane when tested to ASTM E96 Procedure E (<0.075 perms), it is ideal not only for showers and other wet areas, but also for continuous-use residential and commercial steam showers.

The USG Durock™ Waterproofing Membrane meets the permeability rating requirement of 0.5 perms or less and can be used in steam showers/rooms in accordance with Tile Council of North America (TCNA) 2013 Handbook for Ceramic, Glass, and Stone Tile Installation (SR613-13 and SR614-13).
