What is an uncoupling membrane? An uncoupling membrane system provides an intermediate substrate between the tile covering and load bearing substrate. They can be used over a variety of substrates, which include timber, concrete, cementitious screeds and gypsum based screeds.
Is uncoupling membrane necessary on concrete?
Concrete naturally expands and contracts, especially if it’s wet, and these movements can cause cracking. Uncoupling membrane prevents cracks in the concrete from affecting the tiles.
Is uncoupling membrane better than cement board?
Uncoupling mats provide crack isolation protection because they allow lateral substrate movement. Backer boards are made of concrete and fiberglass mesh, and must screwed into the subfloor to secure it. Because it’s screwed down, it can’t provide crack protection like uncoupling mats.
Can I lay tile directly on concrete?
You can install the tile directly on the concrete. You can install a CBU or cement board on the concrete, then the tile on top of that. Finally, you can use an uncoupling membrane between the tile and the concrete.

Sealing the concrete can prevent condensation and protect the floor. This means your carpet or tile stays dry and thus lowers the chances of mold and mildew building up.
Is uncoupling membrane waterproof?
Both a waterproof and vaporproof uncoupling membrane that can be used for crack-isolation in most tile, porcelain, or natural stone installations.
Which uncoupling membrane is best?
4 Best Uncoupling Membranes for Bathroom Tile Flooring
DITRA-HEAT-TB Insulated Uncoupling Membrane. XFasten Fiberglass Waterproofing. Laticrete Strata Heat Mat. Thermogroup Vario PRO ProMat Electric Uncoupling Membrane.
What is underlayment for tile?
Exterior plywood is an acceptable underlayment for tile and is preferred to interior-grade plywoods because the bonding adhesives used are waterproof. If water seeps through the tile installation to the underlayment, it will not cause the wood to swell, as happens with interior-grade plywood.
