Hi All
I need some advice.
We have recently had a large kitchen extension built which involved the knocking though of two rooms and a large new section. Total area is 45m square. The new section has a concrete block and beam floor. In one of the original rooms the existing screed floor was dug out and a leveller applied to get it approximately level with the rest of the extension. Whilst the last remaining section was left as existing screed floor. Electric heat mats were laid throughout the area and a levelling solution was applied over the heat mats. Due to fact the floor was still relatively uneven and in some parts the electric heat mat was still exposed, the tiling contractors said that they were going to have to use a "spot and dab" method to achieve a level floor and not damage the heat mats.
The tiles are ceramic, 560 x 310mm laid in brick style.
The floor is very level and looks good, however three months later a couple of tiles have cracked exposing holes underneath and in another area the tiles are beginning to work loose. Tapping a number of tiles they sound quite hollow and I am worried that I may experience several more loose or cracking tiles over a period of time.
What is the best way to proceed? The tilers were recommended by my builder (his brothers!) Who do you think is at fault? Should the builder have made more effort to make the floor level in the first place and cover all of the heat mat? The adhesive is up to 30mm thick in places. Should all the hollow sounding tiles by pulled up and re-laid?
Help!
