Hi all,
i live in a modern style house and having problems with cracking grout on the kitchen floor.
The house has a concrete floor, with a visquine membrane followed by 50mm poly insulation with 22mm chipboard floating on top.
On this is 6mm blue underfloor heating boards(a polystryne type!) with warm-up heating wires, then tiles, using a flexible grout.
The problem is the grout is cracking which would indicate the tiles are moving, any help to solve this without removing the tiles ie some other form of grout, if not what would the boards adhesive etc would be best to use on a new install
Many Thanks
John
