Kerakoll EcoGuard Biotex Decoupling Membrane 50m²

An uncoupling membrane is required when: the substrate has cracks or is prone to cracking, large-format tiles are being laid, different materials are present in the substrate (screed on wood), or increased loads are to be expected.

Decoupling separates the mechanical connection between the substrate and the tile covering. If the substrate moves (cracks, thermal expansion), this movement is absorbed by the membrane without the tile covering cracking or detaching.

Yes, the EcoGuard Biotex is compatible with underfloor heating systems. The thin membrane (0.65 mm) does not significantly affect heat transfer. For wet screed systems, it should be laid on the cured screed.

The membrane is embedded into the prepared substrate using a suitable tile adhesive. Joints between the sheets must be properly overlapped. Then, the tiles are bonded directly onto the membrane. Application according to Kerakoll system recommendations.
