HYDRO-BLOKĀ® Uncoupling Membrane is a tile underlayment designed for ceramic and stone tile installations. It functions as a crack isolation and waterproofing layer to help manage substrate movement and protect tile and grout assemblies over time.
Manufactured from high-density polyethylene, the membrane integrates beneath tile surfaces to support moisture resistance and compatibility across a range of common subfloor types.
Key Features
- Crack Isolation: Helps absorb substrate movement to reduce tile and grout cracking.
- Waterproof Barrier: Provides a moisture-resistant layer suitable for wet-area flooring applications.
- Antifungal Properties: Helps resist mold and mildew beneath the tile surface.
- Subfloor Compatibility: Suitable for installation over concrete, wood subfloors, and existing tile.
- Installation Efficiency: Eliminates the need for reinforcing mats or traditional screeds.
