Ditra is a polyethylene uncoupling membrane. It has a grid structure of square cutback cavities with an anchoring fleece laminated to the underside. The open rib structure allows for in-plane movement, which effectively neutralizes the movement stresses between the substrate and the tile to prevent cracking. The thickness of the tile assembly is minimized by using Ditra, which is only 1/8 in. thick.

Schluter DITRA is specifically designed for ceramic and stone tile installations.
DITRA is uncoupling to prevent cracked tile and grout. Made of polyethylene,
DITRA serve as a waterproofing layer that protects moisture-sensitive substrates, such as plywood/OSB.
