Is it a concrete or a screed floor underneath. It could be due to the screed cracking. You'll need to lift the tiles to investigate. That'll tell you if its tile or screed related. You are correct about the effect of putting the heating on too hot too fast.
Thank you Ajax123.

It is a concrete floor.
I will be investing in about 3 weeks from now and can confirm then what is happening underneath.

Wow.... that's pretty dam harsh !

I'm a self employed tiler for over 18 years who is looking for a little help and knowledge....not an insult.

Yes theoretically membrane is to be used but in my experience where the area is very small and quality adhesives are used then there is and to date has been no issue until now.

However thank you for your opinion.....you have been most helpful.
Peter, you've got to offer your clients all of the possible scenarios, in this case, you haven't! you've hoped for the best, therefore, you've absolutely "done" anybody who priced the job properly, my question would be, how many times you done this? I reckon loads! Tiling as a trade is rife, more than any other, of blaggers! Therefore, I'll stand by what I have said, and say,no, what I've said is not actually harsh, you're just not doing your job properly!
Therefore, in your "18 years experience" you should have known better to Just do the job properly, no matter the clients budget!

I'll confirm what's happening underneath now, without the need to lift the floor!
You've cut corners!
You've not used the right materials!
You should always fit a smart thermostat!
You are paying for the new floor!
And no, I'm not harsh?
The word you're looking for is
"correct"!

Blimey. I wish I had you as the on my side in some of the complaints I deal with. If you blame the tiler that quickly without any meaningful inestigation it would make my life much simpler. 😜

Hi Peter, I wouldn't take it personally from Benchwarmer as I received something equally as helpful not long after. If I were up still at 2:30 plus on a Tuesday morning I'd be annoyed, or drunk. Either way I'd probably be avoiding Forums. Anyway if its a C2FT rapid adhesive I have seen that full of cracks when I've done removals and tiles like the ones you described aren't that strong. Chances are if the heating was banged on thermal shock tore them apart. We've started to try and use S1 adhesive especially on small floors with no matting and UFH. Thermal shock is devastating without matting though.

Thanks faceman.
Quality brand adhesive C2TES1.
I'll be looking in more detail in a few weeks.
