DESCRIPTION: Decomposed granite, also known as DG, is granitic rock that has weathered to the point that it readily fractures into smaller pieces or chunks of weak rock. Further weathering produces rock that easily crumbles into mixtures of gravel, sand, and silt-sized particles with some clay. Eventually, the gravel-sized particles may break down to produce a mixture of silica sand or silt particles and clay.
USES: is used as a pavement building material. It is used on driveways, garden walkways, bocce courts and pétanque terrains,and municipal urban park and natural regional and national park ‘sidewalks’ and heavy-use paths. It can be installed and compacted to meet handicapped accessibility specifications and criteria, such as the ADA standards in the U.S.
