Building, Construction & Rebuilds

[Janie T]

I am installing a 12x24 above ground buttress free oval pool. I would like to know if anyone has ever used crushed limestone to level the cement blocks for the upright side beams. I would like to hear of any pros or cons regarding crushed limestone as a leveling tool. I know that crushed limestone has been called another name but can't think of what it is right at the moment. Any information anyone has would be most appreciated. I live in Nebraska.
