18 months ago we refurbished our first floor bathroom and had a Devimat installed under the floor tiles. Within six months the grout began to loosen and crack and recently a number of the floor tiles have begun to crack and the grout is looser than ever, even though the Devimat has hardly been on since Spring.
In 20-20 hindsight it seems obvious that as the tiles expand and contract in reaction to the Devimat's heat, the grout would suffer but I imagined this would somehow be allowed for... Anyone been through this or know something that should have been done that hasn't?
