Borrow Pit
A borrow pit is a term used in construction and civil engineering. It describes an area where material (usually soil, gravel or sand) has been dug for use at another location. Borrow pits may be found close to major construction projects. For example, soil might be excavated to fill an embankment for a highway, clay might be excavated for use in brick-making, gravel to be used for making concrete, etc.
