    UFH tiling problem

    Always a tricky one. The standards generally say that moisture resting should be carried out but not who should do it. That said as an "expert" you should be able to offer advice. That you tested it is to your credit. That you went ahead at 7% is debatable in its wisdom as sand cement screed...

    Limestone tiles on a limecrete floor - advice on breathable adhesives and membranes please

    Not necessarily. Depends on the limestone as the coeffiicient of thermal linear expansion for the screed and the stone will be very similar and lime screeds tend to be more flexible and less prone to cracking. Id recomend a conversation with Kerakol as they do a lot of clever stuff for...

    24 year old tile over cement slab floor failing-tenting and popping up

    I very much doubt it's a structural issue. Youd see other issues to accompany it so I reckon you can put that out of your mind safely Thermal shock due to the temperature change would probably do it especially if its underfloor heating. Specially if the heating was turned on at a high...

    was the house flooded in the last few rounds of storms and floods. that could set up a secondary expansion situation in the concrete or the adhesive which could lead to tenting. As Dave said its unusual after such a long time so either something has changed or its always been like that.
