USG DUROCK Brand UNCOUPLING Waterproof & Crack ISO Membrane

The USG Durock Brand Uncoupling Mat is a lightweight, high performance crack isolation, waterproofing and vapor management underlayment membrane for use with ceramic tile and natural stone installations in both residential and commercial applications. The membrane features a low-density polyethylene (LDPE) core to reduce roll-back memory during installation and a reinforced fleece backing keys into mortar providing a secure mechanical bond to the substrate. Its unique dimple design and non-woven fabric allows for minimal passes to fill cavities with mortar. When exposed to stresses from in-plane lateral movement of the substrate, the USG Durock Uncoupling Mat absorbs and prevents the transfer of those stresses (up to 1/8"), preserving the integrity of the tile installation.

• Provides uncoupling, waterproofing, and vapor management of the substrate
• Lighter, thinner alternative to 1/4" tile underlayment panels
• Low density core helps keep the membrane flat during installation
• Rot-proof and resistant to solvents and alkalis / Approved for use with modified and unmodified mortars
• Tile installation can take place immediately after the membrane is installed
