Calculated from your measurements.

How it's calculated

Volume = length × width × depth × quantity. Order volume = volume × (1 + waste ÷ 100).

Calculations use consistent units for your selected measurements. The waste allowance is applied once to the measured requirement. Whole purchase quantities are rounded up.

What this estimate includes

Use the measured excavation depth. Add allowances for over-dig manually; this does not design safe excavation slopes.

Quantity and arithmetic estimates only. Use project specifications for installation and design requirements.
