I have a home built in Arizona. Its on a slab. Parts of the floor are covered in ceramic tile. The tile started popping up near a control join and further down the same large hall along another line that is not a control joint. The control join did not have the slipsheet it should have had, thus the popping tile on the control joint (so I'm told) After they pulled the tile from the other rows that were not over a control joint they discovered another crack, and have told me the concrete is collapsing. I'm assuming this means sinking? or rather moving downward on this end and upward near the control joint. They said if they were to retile it as is the new tile would be a quarter inch above the old tiles near the control joint. The control joint runs the same direction as the rows of tile, right under a line of grout. My question is what should I be asking them to do to repair a 'collapsing' slab?
