Tile Uncoupling Membrane

The tiles are bonded to the top surface of the mat while the loosely bonded bottom fleece is bonded to the concrete subfloor.

Tile uncoupling membrane.

Uncoupling membranes designed for ceramic and stone tile installations provide waterproofing and help prevent cracking. Another solution is installing uncoupling membranes or mats to provide this function in a less intrusive manner. They are flexible non rigid and provide no support for the tiles. The powers that be in the tile industry want uncoupling membranes to be their own classification separate from the cis membranes.

Uncoupling ditra tile has been successfully installed for thousands of years by incorporating an uncoupling layer or forgiving shear interface within the tile assembly. Schluter ditra membranes provide uncoupling through free space which allows for in plane movement that effectively neutralizes the differential movement stresses between the substrate and the tile thus eliminating the major cause of cracking and delaminating of the tiled surface. But the fact is that they haven t been officially tested as crack isolation membranes. Uncoupling membranes in the tile assembly are fast becoming an essential and affordable part of the tile installation process.

They require no fasteners just adhesive to hold them to. This creates the strong bond necessary. Completely fill the square cavities of the uncoupling membrane with thin set. Here are a few tips to ensure all goes as planned.

Uncoupling membranes differ from cementboard in three other important ways. Uncoupling membranes seem like they would prevent cracks also. They are only 1 8 inch thick and raise the height of the finished floor by a negligible amount.
