Noun: A borrow pit is an excavation or hole dug in the ground specifically to obtain soil, gravel, or other earthy material (called "borrow") for use as fill material at a different location, typically for construction projects like building embankments, roads, or foundations.
This term is used primarily in civil engineering, construction, and earthworks contexts. It describes the source site from which material is taken. - The material removed is not "borrowed" in the sense of being returned; the term "borrow" is a technical term for excavated earth used as fill. - The pit itself is often left after the material is extracted.
- Noun:
- The highway construction required a borrow pit to provide clay for the roadbed.
- After taking the needed gravel, the company was responsible for reclaiming the borrow pit.
- The environmental impact assessment studied the proposed location for the borrow pit.
- "to site a borrow pit": to choose the location for such an excavation.
- Engineers must carefully site a borrow pit to minimize environmental disruption and transportation costs.
- The concept is often contrasted with a "quarry" (for stone) or a "mine" (for minerals), as a borrow pit is specifically for unconsolidated earthen fill material.

- The contract specified the type of borrow required for the dam's core.
- Fill (n): The placed and compacted material for which borrow is used.
