About Excavation Calculator
Planning a foundation or basement? The Excavation Calculator estimates the volume of soil to be removed, machine hours required for the job, and the number of truck trips needed for disposal. It intelligently accounts for soil swell/expansion factors.

Frequently Asked Questions
What is the swell factor?
When soil is dug up, it loosens and takes up more space than when it was compacted in the ground. This 'swell' increases the volume by 20-50%, which impacts truck disposal requirements.
How are machine hours calculated?
The calculator assumes an average efficiency rate for a standard backhoe loader (JCB). Normal soil is excavated faster (~25 m³/hr) than hard soil or rock.
