Kitchen floor tiles lifting
I have large porcelain tiles on my kitchen floor which is concrete. The floor was self levelled prior to the tiles being put down but most of them are now lifting and cracking. Some of them can be lifted off whole and there is no adhesive stuck to the bottom of the tile. With one of the other tiles when I lifted it the floor was wet but this dried up quickly as soon as I lifted the tile off. I need to relay the floor but do not know what they best type of flooring will be to put down. Any advice?
Not seeing the problem the only comment that I can make is,from what you have said the porcelain tiles were not laid right they should have been back buttered as well as the adhesive being combed to the substrate this being the normal practice for tiling with porcelain tiles as I have said not knowing what adhesive was used and how it was laid I cannot give any more info,but you might either have a damp problem or a leak if you say the floor was wet,the best type of floor to lay is a tiled floor if done correct.

Was the concrete floor recently laid ? if so the installer probably didn't allow the floor to fully cure, you should allow 4-6 weeks or a week per inch drying time.
If the floor was existing I'm guessing that the installer didn't use the appropriate adhesive for fitting porcelain tiles hence why the adhesive hasn't bonded to the tile.
