Hi,
Relative newbie here, but have had to dig up my living room floor due to cracks and damp issues. Those are now cured permanently, and now we have laid a new DPM and concrete subfloor.
Due to issues, we now have an 11inch drop from the desired floor level and the top of the concrete subfloor.
3" of that will be insulation as approved by Building Control. I can whack another inch on top...
Then I plan to put warm water UFH pipework in, and plonk a flowable screed on top. Are there any limits to the thickness of the screed - ie could I have a 4.5" thick screed (allowing half an inch for the floor covering, which I suspect will be tiles).
I know that the recommended thickness for screed is 65mm, so the proposed 4.5" screed is a little thicker, and would result in a longer warm up time for the UFH.
Any other issues anyone might foresee? Or do I need to whack more insulation on the floor?
