Do I need to add stabilizer to decomposed granite?

Since loose DG does not contain any stabilizers, it is best placed in low traffic areas where it won’t be tracked indoors. Stabilized DG is a mixture of gravel with a light binder which helps the material hold its form more than its natural state.

What are the cons of decomposed granite?

CONS

  • Loose DG will easily erode and become muddy when wet.
  • DG with resin does not provide good drainage.
  • May need to be refilled from time to time and matching up the exact color may be difficult (it’s recommended to keep some of the original on hand)
  • Loose DG can be tracked indoors and damage hardwood flooring.
