Decomposed Granite

If you have never heard of decomposed granite before, here is a short explanation. The color of decomposed granite is reddish-brown. It begins in the form of granite rock and then decomposes into a smaller form or gravel. This form of gravel contains high levels of trace minerals. It can be made in many different sizes and is purely safe for the environment.


Decomposed granite can be used in different ways, even mixed with other substances. It is commonly used for sidewalks, gardens, pathways, patios, trails, playing fields, golf courses and any area where stone or aggregates can be used.


  • Natural DG is used as a mulch material and can be spread around trees and garden beds much like wood mulch. It will continue to weather after it is put in place and provides nutrients to surrounding soil and plants. It lasts longer than most other mulch materials and will not attract pests.

  • For a path or patio, DG with stabilizers (which serve as a binder) is the best solution. Stabilized DG is often added on top of another gravel material, tamped down, then left with a thin loose layer on top.

  • DG with resin for driveways  has a similar surface to asphalt, but has a more natural look and is permeable.

  • While DG is most commonly used for paths, driveways, garden trails, and as a xeriscape ground cover, it can also be used to create smooth visual transitions between formal garden and wilderness. One of its advantages is that it breaks down, so any DG that migrates into lawn or planting beds does not cause problems the way gravel does. Lining a path or patio with a black metal strip (which will disappear if buried low enough) will help keep it in place.
