I need to Level a concrete floor in a room I have knocked through into up to 25-30mm which seems to be in between screed and levelling compound.
Any ideas ? could I build up with say 20mm plywood screwed to concrete and level over that ?
Could I build up with some form of insulation ?
The finished floor will be tiled
