Our Decomposed Granite (DG) is decomposed granite that comes from excavating projects on the side of natural granite mountains. We use a Powerscreen with a 3/8" flat screen to sift out the fines and a magnet to ensure no metal debris. No herbicides, pesticides, or other chemicals are used. It is a natural product that is environmentally safe and does not contain any man-made materials. Our DG is used for pathways, patios, driveways, and desert-scapes.
