  1. Excavate the area where the pathway will be installed to a depth of 4 inches.
  2. Lay down a weed barrier fabric to prevent weeds from growing through the DG.
  3. Add a 2-inch layer of compacted gravel to create a stable base for the DG.
  4. Spread a 2-inch layer of DG over the gravel and compact it with a plate compactor.
  5. Repeat steps 3 and 4 until the desired thickness is achieved.

 Driveways

DG is a durable material that can withstand heavy vehicle traffic, making it an ideal choice for driveways. To install a DG driveway, follow these steps:

  1. Excavate the area where the driveway will be installed to a depth of 8 inches.
