By nature of the product, crusher dust is easy to work with, spread, and level out. As the material settles, the dust and smaller pieces fill the gaps between larger pieces of stone, creating a smooth and compact surface. The material is tightly packed, which means there is no shifting, no moving, and no potholes developing over time.

Description. Crusher Dust is a fine powder like material that can be used as a compactable & screedable base under pavers and slabs. Crusher dust is an economical and sturdy material for pathways and driveways because it compacts to a hard and stable surface. Crusher dust may also be referred to as blue metal dust, cracker dust, and quarry sand.
