Hi All. Thanks for the replies so far.
The tiling was done 4 or 5 months ago as part of a large renovation project. We had no say on who the tiler is but we did make sure to the best of our knowledge that some things were done correctly.
For example, the floor is a suspended floor but we had the builders completely rebuild it with new joists and supports under the joists to remove any deflection to the absolute minimum. It was rock solid with supports every 1.5m. We used Mapei flexi adhesive, matting and the floor was as perfectly level as possible. The tile manufacturer actually sent a rep (Italian company whose name escapes me) to do with another matter and he checked everything and said it was all done perfectly (up to that point)
Now, i know for a fact that there is sufficient gap all round the area and we have done the calculations exactly according to the manufacturers recommendations. We even had to put a gap in the actual area to allow for expansion as the area is quite large.
Did they drill the corners? Well i have to put my hands up and say i have no idea. I did not check as it was not something i was aware of. May I ask, is it true to say that this is something that ALL tilers worth their salt would do? sounds like such a good idea but i genuinely never heard of it before and I have even frequented these forums several times in the past.
Now, for the problem at hand. I am a little stuck here as I am very reluctant to change the tile. Firstly because we used Epoxy grout (Kerpoxy i think) and secondly because we have a wet underfloor system and im concerned about some numpty damaging that which would be a disaster. So, has anyone heard of this infiltrating epoxy before? anyone used it in the manner im suggesting? Its surely worth a go?
edit - re vertical gap. Also not something i was aware of. Manufacturers datasheet only mentioned lateral expansion.
