What are tented tiles?

The term tented tiles refer to floor tiles that have lost their bond to the slab surface and have popped up. Check the video below:

Almost everyone believes that the presence of tented tiles means that the foundation has failed

In truth, the foundation is not the culprit. The root of the problem is a poor application: the tiles were not applied properly. Check out this short video:

Missing soft (movement) joints

Tynan correctly identifies one cause of tented floor tiles: an inadequate gap between the tile and the baseboard. In a specific house, you would have to remove any quarter round material to check for the needed gap. 

Another thing to check is what is known as “soft joints” or “movement joints.” A soft joint is a joint between two tiles that is not grouted. It is typically filled with a colored caulk.
