Trench Volume and Spoil Calculator

Enter trench length, width and depth and see cubic yards of soil, truckloads and bedding stone to plan for.

These tools give planning-level estimates from typical values. They are not quotes, designs or engineering, and results depend on your actual soil, depth, access, local rules and conditions. Only a visit can confirm what a job needs, and we give you a clear price before any work begins.

How it works

Four quick steps.

  1. 01

    Enter the trench

    Length, width and depth in feet.

  2. 02

    Pick the bedding

    Depth of bedding stone under and around the pipe.

  3. 03

    Add a swell allowance

    Dug soil takes up more room than it did in the ground.

  4. 04

    Read the plan

    Cubic yards, truckloads and stone to plan for.

Tips

  • Trench width follows the pipe, not the bucket.
  • Dug soil swells, so plan for more spoil than the trench volume.
  • Keep the spoil pile away from the trench edge.
Questions

About this tool.

Is this exact?

No. It is a planning guide. Soil type, trench shape and equipment change real quantities, and we confirm them on site.

Why does the spoil volume exceed the trench volume?

Loose soil takes up more space than soil in the ground. The swell factor depends on the soil.

How much bedding stone do I need?

It depends on the pipe size and bedding depth. The tool estimates it from your inputs.
