Clean stone or stone with dust
Clean stone, like #57, has gaps between the stones. Water runs through. It is good on top of a drive.
Stone with dust, like crusher run, packs hard. The dust fills the gaps. It is good under pavers, patios, sheds and drives.
Packed stone takes less room. Order about 12% more if you will pack it down. Our crushed stone calculator adds it for you.
