So I can't reuse the current ply? No one has mentioned that before. That would complicates things enormously. There is a fair amount of flex in the floor. You see it bounce a bit if you are heavy footed when walking. Obviously it would be difficult to replace the ply without removing the kitchen. But with the kitchen stretching 7 meters long (L shape) with a composite worksurface and glass splashback throughout + a large island - impossible.
Does anyone else agree with this? Can I negate the effect of the PVA somehow?
Though not guaranteed, I was encouraged to hear Doug's thought on my option 2 with the ditra mat for extra support. Now I am very concerned again. As it stands, would anyone recommend lifting the tiles and replace it with an engineered wooden floor?
Dave & Phil, I know I shouldn't have to pay for any of this, but trying to get the builder back to do anything has been close to impossible. I have considered going down the legal route but having spoken to a number of friends and other people who has had problems with builders - the consensus is it's not worth the bother. No one i have spoken to has ever got anything money back from the courts.
What to do, what to do........my dream kitchen is now a nightmare.
