Tiles sound hollow under underfloor heating - Tile Advice

[J Sid]

the floor will need sand again when tiles are lifted to clean floor.
you need to lift some tiles to see if the adhesive is stuck to the floor or tile.
any expansion joints been put in ?

I don't think expansion joints have been used? What happens if it's stuck to tile?

If the adhesive is on the tile and not the screed it tells you that either the floor wasn't prepared correctly and/or the wrong adhesive used.

200m2 with no expansion/movement joints! Even if everything else was done correctly this is wrong and could be the cause of adhesive bond failing and the tiles becoming loose.
