Tile Uncoupling Membrane

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.

The tiles are bonded to the top surface of the mat while the loosely bonded bottom fleece is bonded to the concrete subfloor. Uncoupling membranes in the tile assembly are fast becoming an essential and affordable part of the tile installation process. Uncoupling is a method that can be used with all of the most common joist spans used in residential construction. The powers that be in the tile industry want uncoupling membranes to be their own classification separate from the cis membranes.

This creates the strong bond necessary. Another solution is installing uncoupling membranes or mats to provide this function in a less intrusive manner. Uncoupling membranes designed for ceramic and stone tile installations provide waterproofing and help prevent cracking. But the fact is that they haven t been officially tested as crack isolation membranes.

Completely fill the square cavities of the uncoupling membrane with thin set. Uncoupling ditra tile has been successfully installed for thousands of years by incorporating an uncoupling layer or forgiving shear interface within the tile assembly. They are only 1 8 inch thick and raise the height of the finished floor by a negligible amount. Use unmodified thin set to adhere the tiles to the membrane.

Uncoupling membranes differ from cementboard in three other important ways. They require no fasteners just adhesive to hold them to. Here are a few tips to ensure all goes as planned.
