new floor in barn / garage ?

[tomo13]

Hi. Have a guy that we are doing some work for that wants a new floor laying in a farm building that he has that he wants to turn into a garage. Concrete floor at the moment, no damp proof. New floor will be going on top of that. Whatever the new subfloor is, is going to be about 4" thick. Doesn't know yet if he wants tiles or slabs (sandstone I guess) of some sort. I can tell them what I would prefer. Would you just go with concrete with bar in or a sand/cement screed ? Thanks

if it doesn't need insulation then I'd go for self compacting concrete. If it needs insulation I'd go for 60mm insulation and 40mm flowing screed... Either way I would put a 1200gauge DPM between the two to stop rising damp.
