Common questions
Why add settling allowance?
Loose delivered soil commonly settles after spreading and watering. The appropriate allowance depends on material and use.
How does Topsoil volume quantity calculate the result?
Cubic yards = length × width × depth/12 ÷ 27 × (1 + settling allowance).
What should I verify before using Topsoil volume quantity?
