Calculate bank cubic metres, swell factors, and transport requirements for earthworks.
* Estimates only. True swell factor depends on actual ground conditions and moisture content.
Whether cutting a basement, leveling a sloped block, or preparing a foundation, accurate volume calculation is the cornerstone of civil earthworks. A critical factor often overlooked is soil "swell" or "bulking."
When earth is excavated from its natural, compacted state (bank volume), it loosens and expands (loose volume). Different materials have different swell factors—solid rock expands significantly more than loose sand.
This expansion means that transporting 100 cubic metres of solid earth requires hauling up to 130 cubic metres of loose dirt. Understanding this logistical reality ensures accurate planning for trucking and disposal.
