Frequently Asked Questions
How do I calculate how much topsoil I need?
Multiply your area in square feet by the desired depth in inches, divide by 12 to convert to feet, then divide by 27 to get cubic yards. For example, 500 sq ft at 4 inches deep = 500 x 4/12 / 27 = 6.17 cubic yards.
How much does a cubic yard of topsoil weigh?
One cubic yard of topsoil weighs approximately 1.1 tons (2,200 lbs), though this varies with moisture content. Wet topsoil can weigh up to 1.5 tons per cubic yard.
How deep should topsoil be for a new lawn?
For a new lawn, apply 4-6 inches of topsoil. For garden beds, use 6-12 inches. For topdressing an existing lawn, 1-2 inches is sufficient.
