Ceramic Tile Uncoupling Membrane

Ditra can be installed over a variety of subfloors including concrete plywood osb and radiant heated floors.

Ceramic tile uncoupling membrane.

The powers that be in the tile industry want uncoupling membranes to be their own classification separate from the cis membranes. It provides uncoupling to prevent cracked tile and grout. It is made of polyethylene creating a waterproofing layer protecting the substrate. It provides uncoupling to prevent cracked tile and grout.

Uncoupling membranes are usually used to uncouple the tiling layer from the substrate and thus reduce the stresses built up between substrate and tile. It is made of polyethylene creating a waterproofing layer protecting the substrate. But the fact is that they haven t been officially tested as crack isolation membranes. Ditra is an uncoupling membrane designed for ceramic and stone tile installations on floors.

The uncoupling membrane does just what it sounds like. It un couples or isolates the substrate from the tile and allows the tile and the substrate to move independently of each other so that movement in the substrate doesn t cause the ceramic stone or porcelain tile to crack. Ditra is a polyethylene uncoupling underlayment with a grid ditra is an uncoupling membrane designed for ceramic and stone tile installations on floors. So this means that they will have their own tests.

Many of the uncoupling membranes available today recommend the use of an ansi a118 1 non modified thin set mortar to bond the ceramic or stone tile to the plastic surface of the membrane. It is still common practice today to install ceramic and stone tiles by direct bonding to the substrate with backer boards.
