Enter the length, width, and depth of the area to be covered into the calculator to determine the amount of decomposed granite needed, and this calculator can also evaluate any of the variables given the others are known.

Dg (Decomposed Granite) Formula

The following formula is used to calculate the amount of decomposed granite needed for a project:

DG = (L * W * D * 0.003) / 27

Variables:

  • DG is the amount of decomposed granite needed (in cubic yards)
  • L is the length of the area to be covered (in feet)
  • W is the width of the area to be covered (in feet)
  • D is the depth of the decomposed granite layer (in inches)

To calculate the amount of decomposed granite needed, multiply the length, width, and depth of the area to be covered. Multiply the result by 0.003 to convert the volume to cubic yards. Finally, divide the result by 27 to convert cubic yards to cubic feet.

What is a Dg (Decomposed Granite)?

Decomposed Granite (DG) is a naturally occurring material that is formed when granite is broken down by weathering and erosion over millions of years. It is a type of rock that is commonly found in various parts of the world, including the United States, Mexico, and South America.

DG is typically tan or brown in color, with a sandy, gravel-like texture. It is often used in landscaping and construction due to its versatility and durability. It can be used for pathways, driveways, patios, and other outdoor spaces, providing a natural, rustic look. DG is also known for its permeability, which allows water to seep through it, reducing runoff and promoting groundwater recharge. It is a cost-effective and environmentally friendly alternative to concrete or asphalt.
