  1. Mark the installation area

    Mark the corners of the installation area with wooden stakes, and connect them with string.

  2. Remove the sod

    Remove the sod and all other vegetation. Remove 8 to 12 inches of soil, and make sure that the excavated work area contains no visible roots.

  3. Install landscape edging

    Apply landscape edging to the perimeter of the installation site, and cover the entire area with weed-deterrent fabric. Remove the string and perimeter stakes.

  4. Lay the gravel base

    Cover the fabric with 4 to 6 inches of gravel. Smooth the gravel surface with the back of a shovel.

  5. Cover the gravel with decomposed granite

    Pour 4 inches of decomposed granite on top of the gravel. Distribute it with a shovel, and then tamp it down with a rolling compactor. Add more granite, and compact it again. Continue adding and compacting the granite until it is 4 to 6 inches deep.
