GURU® G-FLEX Uncoupling Membrane is a waterproof tile underlayment designed to support tile installations over demanding substrates. It provides uncoupling, decoupling, load distribution, vapor management, and waterproofing within a single membrane system.
Manufactured from high-density polyethylene with a raised circular pattern and a thermo-bonded polypropylene fiber backing, G-FLEX helps manage substrate movement and moisture vapor while maintaining consistent bond performance in heavy-duty applications.
Key Features
- Uncoupling and Decoupling Tile Underlayment: Helps isolate tile coverings from substrate movement on critical surfaces.
- Waterproofing Membrane: Acts as a continuous waterproof barrier when properly installed.
- Crack Isolation: Meets ANSI A118.12 requirements for crack isolation membranes.
- Vapor Management: Raised pattern supports vapor pressure compensation when moisture is present in the substrate.
- Load Distribution: Designed to help distribute point loads across the substrate.
- ANSI Compliant: Meets or exceeds ANSI A118.10 and ANSI A118.12 standards and is accepted by IAPMO.
Common Applications
- Commercial kitchens
- Food processing facilities
- Dairies and breweries
- Airport facilities
- Other heavy-duty tile installations
