Guys I really appreciate all of your comments. I have taken note of everything that has been said. Seems like multiple problems have caused this to happen. I Think we are going to lift the floor and start over

Apart from the moisture the adhesive used states suitable for anhydrate screeds.....

Yeah a lot do now John, what they actually mean is that it must be primed first, which I feel is very misleading to be honest.
It’s just an S1 cementitious adhesive, so it would depend on your interpretation of the word ‘suitable’ much in the same way that hardiebacker is ‘impervious’ to water. 😵

Back buttering would have helped on tiles that are so big for sure but those levelling clips simply lift the tiles out the adhesive. I used them once and can remember having a problem with the tiles creaking as you walked on the corners as there was insufficient bed in the corners due to the lift of the clips.

Not going to get in to a clip debate in this thread, but if that problem occurs due to clips being used, it’s because they’ve been used incorrectly.
There are numerous threads on the forum that address this issue.

Couldn’t agree more Marc.

I would just suck this one up Gary if you can afford it and put it down to experience, we all have to eat a shilt sandwich every now and then, I've eaten one or two over the years. The insurance co will have their pound of flesh in the long run and more besides.
