Crushed Sandstone primarily used for compaction under roads and in construction. Our Crushed Sandstone comes in 75 mm minus, but often some of the rocks can be a little bigger. The larger rocks in the crushed sandstone are great when you're after a rougher looking finish. For this reason they are not the best suited for pathways.
