It is a lightweight uncoupling membrane that will prevent tile and grout from cracking as the floor below moves and flexes. The free space provides an escape route for excess moisture and vapor that could otherwise cause damage to the tile layer above. The ability of ditra installations to support and distribute heavy loads while preserving the integrity of the tiled surface has been verified through extensive laboratory and field testing, including applications exposed to vehicular traffic.

But, yes, it can help prevent cracks from forming in the tile in plywood or concrete. The ditra matting has many functions that make it an ideal product for tile installations: Ditra offers no loss of vertical strength for building upon.

Ditra is an uncoupling membrane designed for ceramic and stone tile installations on floors. The ability of ditra installations to support and distribute heavy loads while preserving the integrity of the tiled surface has been verified through extensive laboratory and field testing, including applications exposed to vehicular traffic. The membrane provides a shear interface within the tile assembly, which allows the substrate (base) and surface (tile or stone) to expand and contract independently of each other.

It is made of polyethylene creating a waterproofing layer protecting the substrate. Through uncoupling the floor covering from the substrate, ditra matting can stop stress cracks being transferred from the substrate to the surface covering. Add a strip of waterproof membrane (such as schluter.

The product is 3.29 ft or 39.5 wide for calculating square footage. The product i needed is called the schluter ditra xl. I said that ditra is “relatively” recent.
