These free results do not automatically save or sync to a Fieldlink job.
How it works
- Loose = bank × (1 + bulking %)
- Bank = loose ÷ (1 + bulking %)
- Loads = loose ÷ truck capacity (rounded up)
Worked example
150 m³ bank @ 25 % bulking = 187.5 m³ loose = 21 loads @ 9 m³
Assumptions and practical notes
Bank = in-ground, loose = on the truck, compacted = placed fill. Check payload as well as bin volume for heavy material.
