first we nailed hardboard down on the floor and then put the stud walls etc up. We fitted the kitchen and then put floor tiles down. Thats where the problem lies.
The hardboard has 'bubbled' and now a few of the tiles move when you stand on them.
The grout has also come off a few of the tiles due to the movement in the hardboard. Is there any way round this without having to lift the whole floor? We really dont want to do that as the kitchen looks really well.
