QUESTION

Why are my ceramic tiles Tenting and Debonding? - I have a two story house with for rooms and my ceramic tile floor has tiles that are tenting up and debonding, but there are no cracks in the concrete.

ANSWER

ANSWER - I understand that you have ceramic tile installed onto a concrete floor, and some of the tiles have tented up and debonded.

There are likely compounding deficiencies in how the ceramic tile was installed that has led to your problem. The concrete substrate may not have been properly prepared that has not allowed the tile to bond to the concrete surface. The installer may not have installed the tiles correctly in how the adhesive was used and he may not have installed expansion joints into the tile work.

If all the tiles are coming loose then they all have to be replaced, but to avoid the same problem a second time then you have to make sure the substrate is properly prepared and the tile is properly installed. Good luck.
