We are currently at the planning stage for a floor with bifold windows and wet underfloor heating.
Basically the tiles near the windows will need to go over the screed and onto a concrete block on the perimeter (red arrows). I'm concerned that the screed with the insulation under it is likely to move (a little) and the concrete perimeter block will not - so we will end up with a crack line in any tiles we put over it (orange dotted line).
Is this actually a problem, and if so what do I do about it.
Thanks Simon
