Uncoupling Membrane Advantage

A Must-Have For Tile Installation

The uncoupling membrane keep your tiling floor integrity, long-lasting beautiful and away from cracks through 4 key function: uncoupling, waterproofing, vapor management, and heavy load distribution.

Uncoupling Effect

Between tiles and substrate, it generates a differential movement stresses.

This differential stress is the critical reason for tile cracks.

Our membranes cancel out this stress by the open rib structure which allows for in-plane movement and protect the tile flooring.

Load Distribution

Heavy load usually causes fractures of tile covering.

Due to the grid design, lots of mortar columns structures are formed after installation.

These densely mortar columns can share and transfer the load evenly, prevent fractures.

Waterproofing & Vapor Management
