Hi everyone!3 months ago I've tiled my kitchen with an underfloor heating cable underneath( originally it was a bitumen floor, what I've done: I've laid a insulation floor boards using a flexible tile glue installed heating cables and and laid my tiles straight on the top ) everything went o.k, until I've noticed that couple of tiles moving(grout coming off).Don' know what to do. Looks like another massive job
many thanks!

Polished porcelain floor tiles, evo-stik flexible tile adhesive, ultra flexjoint grout. Ufh wasn't on at least a week after installation.

When you turned the ufh on, how did you go about this process..?..

If its only a couple of tiles moving,try lifting them out without breaking them,if not use new tiles,Clean the old addy off the floor,being careful with the UFH wires,check the floor is solid then simply refix the tiles and re-grout
