Hi
I have a clients floor I laid in December 2013 that has tiles coming away from the adhesive.
The job was 100m2 of White Polished Porcelain (600x600) to be laid on 18mm ply which was biscuit jointed all over on 300mm joists. Across a Kitchen, Utility, Study, WC, Hallway, Lounge and Dining Room. The floor was pretty sound only one area slightly concerned me (where there has been no issue at all) There is wet underfloor heating across the entire floor underneath the ply.
I laid ditra mat across all the floors, this was filled and then the floor was laid. We used BAL Rapid Set Flexible in the Hallway and a couple of other areas. The rest of the floor was laid in BAL Single Part Flexible. Grout was BAL Micromax 2.
In every doorway I put in an expansion joint in between each room and every room apart from 1 wall in the lounge had at least a 3mm joint between it and the tiles
In March time the customer contacted me to say they had a clicking noise coming from the tiles which they suspected I hadn't put enough adhesive under the tiles. I went over and found that the noise was coming from 6/7 tiles by the front door and upon inspection it looked like the floor had dropped 2-3mm by the front door as you could see my grouting had 'split' (pic 1 & 2) I assumed it to be an issue with the sub floor and the customer didn't want to remove all the tiles so we decided to leave it and see what happened.
Earlier this month the customer had called me again to say that more tiles across a couple of other rooms had also started 'clicking' so I went to see the customer this week and the same clicking is happening in different areas across the floors.
I don't know why this is happening? There is no grout cracking, no tiles are cracking.
The only thing that doesn't quite make sense is that in areas where I have grouted up to something it looks like the floor has dropped 2-3mm please see pics. In the WC which we fully tiled it the wall tiles have come away from the floor tiles by 3-4mm??
The customer did a lot of research in to the sub floor and was sure it was sound. For example in the study the joists were resting on a concrete base so there should be no movement but there is?
Sorry for the essay but there's no easy way to explain it
What do you think?
