Soil Removal Calculator
Work out the bulked soil volume and number of truck loads needed to remove spoil from your site.
Soil Removal Calculator
Work out bulked soil volume and disposal truck loads for spoil removal.
Estimating Soil Removal And Disposal
Once soil has been excavated, it needs to be carted off site and disposed of, and this calculator is focused specifically on that logistics side: how much bulked volume you are dealing with and how many truck loads it will take. The starting volume is area (m²) × average depth (m), and a standard 25 per cent bulking allowance is then applied, since excavated soil occupies more space than it did compacted in the ground.
You can choose a truck size to match your site access — a 6 m³ truck for tight residential sites, a 10 m³ standard tandem for typical access, or a 12 m³ truck where larger vehicles can get in and out easily. The calculator then divides your bulked volume by the chosen truck size and rounds up to give you a realistic load count.
What Information You Need To Enter
Enter the area being excavated in square metres, the average depth in metres, and select the truck size that matches your site access.
Understanding Your Results
The calculator shows your raw excavation volume, the bulked volume after the 25 per cent allowance, and the number of truck loads needed at your selected truck size. Use this figure to budget disposal costs and schedule trucks for the job.
Why Accurate Estimating Matters
Soil disposal is usually charged per load, so an accurate truck count avoids under-budgeting for a job that ends up needing several extra loads once the bulking factor is properly accounted for.
Frequently Asked Questions
Why does site access affect truck size?
Larger trucks are more efficient per load but need more room to manoeuvre. Tight residential sites, narrow driveways or overhanging trees often mean a smaller 6 m³ truck is the only practical option, even though it takes more loads to clear the same volume.
Where does removed soil go?
Soil is typically taken to a licensed disposal or recycling facility. Costs vary depending on soil type -- clean fill is generally cheaper to dispose of than contaminated or mixed soil.
Does this include the cost of disposal?
No -- this calculator estimates volume and truck loads only, since tip fees vary by facility and soil type. Contact us for a full quote including disposal costs for your project.
What if my soil is contaminated or mixed with other material?
Contaminated soil or soil mixed with concrete, brick or other waste usually requires special handling and disposal, which affects cost. Let us know if this applies to your site when requesting a quote.
Is the bulking allowance the same for all soil types?
This calculator uses a standard 25 per cent allowance suited to typical Melbourne residential soil. Rock, clay or heavily compacted material can bulk differently, so treat this as a solid planning estimate rather than an exact figure.
