Clean 3/4–1 inch gray limestone. Water moves through it—drains, concrete base, driveway topcoat.
Gray crushed limestone, 3/4 inch to 1 inch, with no dust in the mix. Water moves through it, which is why it is the usual choice for French drains, drainage, a concrete base, or a driveway topcoat that needs to stay open. If the job is drainage, this is often the right rock.
