Tile floor lifting
Had a karndean floor fitted.The (30 years ago), original floor was marley tiles on bitumastic. The floor tiles were removed and virtually all the mastic then SLC laid and new floor fitted There has been a couple of water leaks washing machine, freezer in that time. Before the latest new floor was fitted I pulled up the old cushion floor and took up the broken bits of SLC. When the fitter
came I pointed out the areas of damage and he said no problem. He had a good clear up and laid some more SLC over the entire floor. 6 months down the line the floor tiles have lifted in one central area. Fitter came back pulled up a tile both layers of SLC came up with it. He checked it with a damp tester It went off the scale. We have not had any leaks. His boss said that it was our problem as the original SLC had not had any primer laid first. The moisture from his SLC apparently had gone to the subfloor and as it dried out had lifted everything above. The SLC 30 years ago is apparently different than what is used now. Was primer used then? There was 4 days between SLC and floor laying, is that enough?
Basically I do not know where to go from here I cannot really afford another £900 to have the complete floor removed and a new one laid.
Any help would be appreciated.
i suggest the next fitter preps the floor properly next time. he should of checked damp before. all existing floor residue should have been drinded off back to concrete. then a one coat dpm should have been lain. then a primer for bonding of latex to dpm. at a minimum of 6mm and that floor would be perfect. please be aware some fitters can lay floors, but have no knowledge of preperation. which is the most important part.

I would suggest remove all the karndean floor and fit tiles, much better for kitchen areas.
