I am working out the details of a floor construction for a single storey extension. Each guide I look at asks for a different thickness of screed, some don't reference at all. I am trying to keep the overall thickness of the non-hardcore layers down due to shallow drains running under the floor, and I am considering excluding the screed, or using the absolute minimum thickness.
What actually is the purpose of the screed layer when directly on top of the concrete slab? Could the final finish be a levelling compound or similar straight onto the concrete floor? If no, what is the absolute minimum screed depth? There is no underfloor heating.
with thanks!
