Well, turns out it is electric underfloor heating in a basement flat. I don't have a clue about the preparation of this stuff. But, the tiles are all becoming loose, cracking in places and grout coming loose.

Sounds like it's probably just a case of using the wrong adhesive, or maybe there's damp under the floor?

They need to get the tiler back mutley not the plumber sounds like some clown has put normal tile adhesive instead of flexible tile adhesive. The adhesive can't cope with the expansion and contraction and starts to disintegrate thus causing the tiles to move and crack and then the grout is moving because the tiles are moving

Honestly don't know why anyone uses that ready mixed rubbish. It's a nightmare waiting to happen.

How thick is screed?
How long was it left to dry
How wide is the floor
Are they polished proc 600x 600
What expansion joints included
What's the screed!

I'd never dare tile onto a new screed, the tilers forum boards are a wash with cracking screed threads. It really puts you off.

Tiler blames plumber, plumber blames screeder, screeder blames plumber and tiler, tiler,plumber and screeder blame the screed delivery driver, delivery driver blames some guy walking past out with his dog.

I feel left out. What's wrong with the normal practice of blaming the merchant?

It was done in 2007 so doubt they will come back and fix it. I shall let the client know that it needs re-tiling with flexible grout.

Thanks for all the help guys. Much appreciated

It might have been turned on too soon. Should be two weeks after tiling.
i would recommend taking the tiles up( this will probably destroy the element) then fit new underfloor, re-tile using bagged SPF( single part flexible) adhesive and grout using bal superflex grout.

Any outcome to this?
