USG Durockā¢ Liquid Waterproofing & Crack Isolation Membrane
USG Durockā¢ Liquid Waterproofing & Crack Isolation Membrane is a liquid-applied waterproofing membrane designed for use beneath ceramic tile, porcelain tile, natural stone, and other finished surfaces. It provides waterproofing protection while helping isolate minor substrate cracks that can transfer through tile assemblies over time.
This liquid membrane is commonly used in showers, tub surrounds, bathrooms, kitchens, laundry rooms, and other moisture-prone environments where waterproofing beneath tile is required. Once cured, the membrane forms a continuous waterproof barrier that helps protect approved substrates from water intrusion.
Primary Functions
- Waterproofing:Ā Creates a continuous waterproof barrier beneath tile and stone installations.
- Crack Isolation:Ā Helps accommodate minor in-plane substrate movement beneath tile assemblies.
- Substrate Protection:Ā Helps reduce moisture penetration into approved wall and floor substrates.
Common Installation Areas
- Showers and shower walls
- Tub surrounds
- Bathroom floors
- Kitchen tile installations
- Laundry rooms
- Interior and exterior tile applications
Liquid Waterproofing Membranes for Tile Installation
Liquid-applied waterproofing membranes are commonly used beneath tile installations because they can be rolled, brushed, or troweled directly onto approved substrates. They help create continuous waterproof protection around corners, transitions, and irregular surfaces while supporting long-term moisture management beneath tile assemblies.
Selecting a Waterproofing Membrane
When selecting a waterproofing membrane, consider the installation environment, substrate type, waterproofing requirements, and whether crack isolation protection is needed beneath the finished tile assembly.
