How Much Does 1 Cubic Yard of Decomposed Granite (DG) Weigh?
One cubic yard of decomposed granite weighs approximately 3,510 pounds (1.75 US short tons) in its standard loose state, based on a dry quarry bulk density of 130 lbs per cubic foot ($3,510\text{ lbs/yd}^3$).
Why DG Weighs More Than Standard Gravel:
Standard gravel has air voids between individual pebbles. In contrast, decomposed granite consists of granite grains blended with natural rock silt and stone flour. The fine particles settle into the void spaces, creating an exceptionally dense, high-mass material.
