Cracker Dust, also known as decomposed granite, Blue Metal Dust or Crusher Dust, is a fine crushing of our local blue metal. It is most commonly used as a base under artificial lawns, in paving screeds and also can be used in pathways and driveways. Cracker Dust compacts down well while continuing to provide good drainage. You can stabilize Cracker Dust with Soilbond or Cement to aid compaction and reduce erosion.
