A limestone gravel that has been crushed and graded to a 1 1/2” base. Widely used for surfacing roads, driveways and parking lots. A combination of course and fine aggregates that form a solid base of support ideal for firm structural foundations. Unlike clean gravels, Crusher Run Gravel also contains a mix of fines (stone dust) that blend together with the angular crushed stone creating its desirable compaction and drainage properties.
