QUESTIONWhat is the difference between Tile Debonding and Delaminated Tile and Tented Tile?
ANSWERANSWER - Whether it is stone tile or ceramic tile or porcelain tile or glass tile, if the tile becomes loose or unbonded, then we refer to that either as a tile that debonded or we might say the tile has delaminated from its substrate.
If the tile has lifted off of its substrate at some point of the tile installation, but is still attached to the adjacent tiles by the grout joints, then we call that a tented tile. In this case the tile has delaminated from its substrate or come loose, but is held together by the adjoining tiles. You can normally step on the tented tile and it will move up and down to some degree. Normally this condition is due to the tile not being bonded as well as it could be and because there is a lack of movement joints to mitigate the expected expansion in the tiles.
