Which component is used for crack isolation in tiling?

The component designated for crack isolation in tiling is specifically designed to prevent cracks in the substrate from transferring through to the tiled surface. Crack isolation membranes are engineered to absorb and mitigate the stresses and movements caused by fractures in the underlying structure, effectively isolating the tile from these potential damages.

These membranes can be installed beneath the tile in a way that allows for flexibility, preventing the cracks from appearing on the tile surface while maintaining the integrity of the tile installation. By using crack isolation membranes, you enhance the longevity of the tile work and minimize the risk of future structural issues, such as cracks or breakages in the tiles.

Other options such as waterproofing membranes focus primarily on preventing water damage and moisture intrusion but do not specifically address crack isolation. Thin set additives and polymer modified mortars enhance adhesion and flexibility of the mortar but do not provide the same level of crack isolation as dedicated membranes do. Thus, for effective crack isolation, crack isolation membranes are the most appropriate choice.
