Tile moving and grout breaking

Irrelevant! She’s established it’s not been primed. You don’t even need to have ufh for this to happen. It’s a chemical reaction between screed and cement!

I missed that it hadn’t been primed. That won’t help either depending on the adhesive used of course… (I might have missed that as well)

in all fairness bud, adhesive won’t play a part either, what happens is,as this type of screed dries the moisture rises to the top as it dries and forms a mineral on top, in effect a barrier between floor and tile,(so your sticking to the mineral and not the floor,this needs to be ground/sanded off then primed twice, one diluted,usually 1 part primer 3 parts water which will soak in and when dried,you will then go over again with neat primer.
Because even after sanding the calcium screed reacts all cement based adhesives hence the need to prime

Hmm… best not get into a debate about anhydrite…

Hi all, since we last spoke I wanted to provide a bit of an update.
I got a professional tiler to come have a look at the problem. He had provided me with a report which clearly states no preparation of the floor as he found dust when he lifted the tile. The tile came off easily.
I have sent the toilet a letter with the report on mail and asked him to rectify the problem. He called me today evening two days after getting the letter and was screamy, not ready to accept responsibility. He said he didn't did any contract as we agreed things verbally and hung up on me.
I have been advised by citizens advice to give him 14 days in the letter and did give him the option of alternative dispute resolution before proceeding to the next stage.
I have tried to ask his friend to put some sense in him.
I do have his company details which was included in the letter. I have screenshots of the WhatsApp chats and the bank transfers.

Should I be hopeful?

A long shot. But there may be hope.

Any update now given the time passed?

Hi @Dan , I sent another letter which was the letter before court action. The tiler called me straight after receiving the letter and offered to visit. They brought someone with them as a mediator. We have them a tour of the shoddy work they had done but I wasn't surprised when they didn't accept any responsibility. Kept on blaming us by saying they applied what we had provided and that all liability lies with us. The mediator was more level headed and saw the argument for what it was. After numerous hours of phone calls we have another follow up on a few weeks time. The tiler did say they would rip and put the tiles down again this time with preparation. But the tiles have to be provided by us. We are going to speak again to see what their proposal is and maybe come to a compromise. I don't know if going to court is fruitful. From what I have read, the court will also recommend mediation. And am not sure if the court can mandate that the tiler pay the damages in full if the case decision is in my favor. It would be good to get some clarity if it's worth pursuing or not. New tiles aren't going to be cheap and we will have to live through the disruption.

taking the matter to court will cost thousands and take at least a year.
It's unfortunate but I would offer to pay for new tiles (if the old ones cannot be saved) and let him pay for adhesive and primer and provide the labour.

Not sure if this has been mentioned on this thread but I've seen this happen before on the type of screed described. And this was when the screed was dust free, primed with acrylic primer several times with movement joints installed and flexible cement based adhesive used as per manufacturer guidelines. What I believe solves this problem would be to install a decoupling Matting such as Ditra or a similar product. The substrate would need to have dried properly and prepared properly prior to fixing the Matt with flexible adhesive. Yes the cost would be more for the customer but it would avoid what's been explained in this thread.

Hey Rutters, the mat was mentioned to us by Topps Tiles as recommended but the tiler didn't. I will keep that in mind for the rework. They aren't cheap as you said but a job well done says all this hassle.

Hi @Slippery thanks for the advice. Am going to talk to the tiler and his mediator and see where we can find common ground. The work will have to be done early summer next year now that we have started using the heating in the house.
