Hi,
I need to level an uneven concrete floor before installing insulation and screed. I've seen that some people suggest using sharp sand to fill the hollows. does this sound reasonable? I think it would work as all it needs to do is allow the insulation to sit level?
I cant use letex or levelling compound as the area is too big and it would cost a fortune
