Tile Expansion Joint

Tile expansion joints are spaces or gaps left between tiles to allow for expansion and contraction due to changes in temperature and humidity. They are usually placed at regular intervals around the perimeter of the tiled area and along the grout lines between tiles. Expansion joints are necessary because tiles can expand and contract due to changes in temperature and humidity, and if these movements are not accommodated, the tiles can crack or become damaged. Expansion joints allow the tiles to move independently of each other, which helps to reduce the stress on the tiles and prevent damage. Expansion joints should be wide enough to allow for the maximum expected expansion of the tiles, but not so wide that they are noticeable or create trip hazards.
