High-rise buildings and other vertical constructions are subject to constant movement and vibrations that can compromise the bond of tiles, leading to them popping up. It is extremely important to use a flexible crack isolation membrane to compensate for movement between the concrete surface and tile adhesive. The tile mortar specified for this application must be highly deformable and flexible to compensate for shear and tensile stresses on the tile adhesive. Finally, a high- performance non-shrink flexible grout is also strongly recommended.
