When “weakness” is true strength

It is a consolidated principle in nature that flexibility constitutes the true strength of a plant or tree. Just think of poplars or bamboo canes that bend in the wind without breaking. Even in the world of construction, the flexibility of the structure is among the fundamental principles guaranteeing its resistance. A rigid building, incapable of adapting to the movements of the ground and the different expansions of the building materials, it would be particularly fragile and subject to the risk of cracks and collapse. Nevertheless, in the world of ceramic flooring, the use of glues for thin bed installation has become widespread, on the contrary, an incredible adhesion force. This total membership, necessary for bonding low porosity materials such as modern porcelain stoneware, it can represent a problem for the integrity of the tiled surface. The ceramic is bonded with incredible strength to the substrate and with this rigid "welding" it loses the ability to compensate for the different movements and expansions, and sooner or later, if it breaks.

Schlüter®-DITRA, separation in adhesion

To overcome this problem, Schlüter®-DITRA was born. Thanks to a system patented for over 25 years, the sheath creates an "adhesion separation" between the ceramic and the substrate. The "separation" is guaranteed by the material with which the membrane itself is made, he PET, hostile to any type of gluing. The "adhesion" is instead guaranteed by a mechanical dovetail anchoring system offered by the small truncated pyramids of the sheath, where the glue is distributed. Background, the sheath and ceramic layer are thus solidly connected to each other, but at the same time free in their different expansions. The risk of breaking the tiles is avoided.
