I had porcelin tile put down two yrs ago, and recently it began to come up. I removed one of the tiles to find the concrete damp underneith. What is the best way to remove the old tile, and what can I do to prevent this from happening again.
need more information,where is the tile installed,what did you use to glue it down? did you do a moisture test? please give as much info as possible,will try to get you answers.
The tile is placed in a room addition that was installed before purchase in 1985. There is a concrete slab down, and I did not moisture test it. Thinset was used to glue the tile down, and most of it came up on the tile I did remove. It appears that about 9 tiles are loose, at least I hear hollow sounds when tapping it. I have no extra tile and tile was discontinued.
i think you have answered your own question,the thin set stuck to the tile but not the slab.that means its not the thin set.that leaves the floor and you already found moisture.so if you take up the rest of the tile,some will break,and the ones you do get up ,you cant get the thin set off. to make the best of a bad situation i would try this use a tile mastic to put down only the tiles that have come loose,and re grout as needed.try to find out why the slab is still wet, is it below grade?is your home a little bit lower than the house's around you?if so you are experiencing "hydrostatic pressure"(water coming up through the cement) the fix for that is a french drain.good luck
