Hi There,
I have a newly laid concrete floor, with newly laid UFH. The builder gave 28 days, and then installed "fanal iceberg polished tiles", 750X750 size. We gave another 28 days before starting up the UFH. Its around 110sqm area. Few of the tiles had to be cut near stairs, etc.. and I have now noticed that there are cracks on some of these tiles. These tiles are one of the best, but the builder is telling me its common for tiles to break, when they are cut.
I am totally disappointed with install, since , these were expensive tiles and after seeing up to 5 tiles having a crack I am very disappointed. What can I do now? why do they crack? Has the builder done a bad job?
Thanks in advance for your comments. Regards G
Are you a tradesperson and able to answer this question?
I expect the cracking is due to the wrong adhesive used,
If the floor wasn't screeded level this can also be a problem...
Hollow areas where he may of leveled the tiles out could also create this....
You need to go back and say your not happy, maybe get an independent company to come and have a look.

I expect there are a number of issues that has caused the cracking of the tiles.
They may have used the wrong type of adhesive to allow for some movement due to the UFH system.If the floor wasn't level and hasn't been screeded level then this will allow for hollow points when laying your tiles and if they used a levelling system then this would be compounded as no coverage would cause cracking.
You need to give the company chance to repair there errors and if they don't I would report them.
Kind Regards
Chris

As answers above, but should definitely of used an S2 cement based adhesive and Anti-Fracture/Uncoupling matting.

Ok so was a decoupling mat used ?
And how was the UFH commissioned when turned on was it turned on gradually if not this can cause cracking to newly installed tiles.
I would always recommend the uses of a decoupling mat to new screeds
