Detached or broken tiles are oftenly observed in tile and stone installations on exterior facades. The abrupt temperature changes caused by periods of intense sunlight followed by sporadic rains result in temperature variations of up to 15°F, causing concrete to expand and contract and tile bond to fail. It is recommended to apply a crack-isolation waterproofing membrane to compensate for these movements and to prevent the passage of salts present in the concrete, which can lead to efflorescence issues on the surface. This application also requires the use of high-flexibility and deformability tile mortars and grouts.
