Bathroom tiles lifting in new build extension

[John Corbett]

Hi

I hope someone can offer advice please. We had a large 2 storey extension on the side of our house 18 months ago. One of the new rooms created is an upstairs bathroom. We had a tiler tile the walls and floors. It looked fantastic but over time grout started to come out of some of the tiles and I could hear the tiles moving slightly when stepping on them. After around 9 months a large gap of approx 6mm had appeared all around the bottom corner of the room in the grout. I called the tiler back in and he regrouted the corner of the room. I mentioned 2 tiles seemed to be moving. And he said yeah they've popped. He didn't really say much of what the cause was. Muttered something about movement in extension floor and said he'd have to remove the toilet as one tile was under the toilet. He came back and bought 2 new tiles removed the toilet and replaced the 2 tiles at no charge. Since then more tiles are moving and small pieces of grout are coming out around these tiles. I did text him but I haven't heard back from him. I suspect that the significant drop in the floor has caused the tiles to lift. None have broken but I suspect it's a matter of time. I don't know what to do to resolve the situation. Any advise if anyone had had major problems with floor movement in new builds ? Cheers John

There is only one sure way of finding out and that is to remove a tile and see what is going on underneath. If the tiles are loose it may be possible to remove one without too much inconveiniance. If you can also send in some pictures of the floor type and the back of the tile we may get more of an idea of what is going on. The spaces should not be left in as the grout won't stick to these and would de-bond and they will stop the grout joint being fully compacted.

Thanks for your advice guys. I was thinking of going back to Tile Choice and having a chat with them. The tiles that have lifted are all on the same side of the room. The ones under and around the bath are still sound. Not sure if this is just because the ones that have lifted are the ones we walk on most. I need to make a decision soon as I can see a tile breaking before long.
