swell (bulking)

In French: foisonnement

Definition

The increase in volume of soil once it is dug: one cubic metre in place becomes more than one cubic metre in the truck, because the grains are no longer packed. Clay swells more than sand or gravel. Truck trips and containers are sized on the swollen (loose) volume.
