Swell Factors for Various Soils
· Swell Factors for Various Soils. A cubic yard of earth measured in its natural position swells to more than a cubic yard after it is excavated. This occurs because of an increase in voids. Swell is expressed as a percentage of natural volume, for example, if 10 yd 3 in the ground becomes 13 yd 3 after excavation, the swell factor is 30%.
