Why movement joint profiles are used? Ceramic, granite, porcelain, stone, glassy ceramics, concrete and marbles tiles and terrazzo floor cover applications require thermal expansion joints profiles to absorb natural movements. The temperature difference causes expansion and shrinkage in water or moisture coating, so all the tiles shrink with drying and cooling. Another reason, dynamic structural loads cause vibration and large movements in the applications. If expansion joint is not used in tile, ceramic, granite or marble applications, internal stress due to expansion or internal shrinking can cause many problems such as obvious cracks and breakage. Therefore, joint design extremely significant for the life of coatings.
