Hi all, have a timber floor which is rotten, laid on a concrete sub base which appears to be solid, they have laid 3"x 2" timbers flat with chipboard on top and then tiled. Want to replace wooden floor with extra DPM, insulation and a screed over the top. I know that the 2" insulation should be under the concrete, but we only have 4" to play with and don't really want to break old concrete up as it is solid. Any ideas on this apart from doing what I don't want to do, the room is 8' x 8'. Thanks for your time.
