Decomposed Granite is the ultimate for driveways and pathways. Mined in the Texas Hill Country, this material has small, coarse granite chunks and lots of fine material. When installed as a driveway or pathway, the fine material takes a hard set, while the coarser material rises to the surface. It all stays in place, yet quickly drains. Decomposed granite is a good surface for walkways, driveways or as a well-drained surface in pet kennels. Using decomposed granite provides a natural look to any surface and many people are able to install it themselves.
