3/4 Clean Basalt
Crushed rock that has no rounded edges, it is 3/4" nuggets with the "fines" screened out. It is used on softer driveways, pathways, and behind rock walls. It has better drainage, because there are no "fines" in it. It spreads well when wet, which makes it great for driveways in the wintertime. It is dark charcoal gray in color.
