I have recently moved in to a victorian terrace where the ground floor is all quarry tile,however there is no sign of damp whatsoever. The problem is the whole floor throughout is uneven and a difference of around 3inch from the highest to lowest point. I don't fancy digging the lot up and laying concrete and screed. I was thinking of using tanalised timber battens screwed down level and installing reclaimed oak floorboards on top, at the same time installing insulation bats between the battens. Would anyone have any suggestions on this or do's and don't's, thanks Roger
