Sorry to dredge this old topic up but I thought it'd be better than starting a new topic for a similar question.
Has anyone here put down a solid floor without any concrete or even screed? Just sand, DPM, insulation and a floating chipboard floor, or would that be too unstable for a domestic load? (it's in the living room)
I have read that the screed is likely to crack if you don't have concrete beneath it, but access to the house is limited so we probably couldn't fit a tanker in, and I don't have a cement mixer (plus I'm not sure if mixing my own would be practical over such an area), so while I want to do everything properly, I'm wondering if there is an alternative to concrete?
