What this tool does

Soil swells when it is dug out, typically by 20–30 %, so the spoil you have to remove takes up more space than the hole it came from. The last figure estimates 8 m³ truck loads for that loose volume.

Formula

V = c × l × p ; loose volume = V × bulking

Limitations

  • The result is an estimate based only on the values you type. Real situations often include factors this calculator does not know about.
  • Density changes with temperature, moisture and composition. Use a value from the supplier's data sheet whenever precision matters.
  • Always order a little more material than the calculated quantity. Cuts, breakage and pattern matching create waste that depends on the shape of the job.
