What term refers to material that is imported to a site for construction purposes?

The term that refers to material that is imported to a construction site is commonly known as "borrow." This term specifically denotes soil or other materials that are extracted from one location (often referred to as the borrow pit) and transported to another location for use in construction projects, such as grading or filling.

In grading processes, "borrow" is essential because it provides the necessary material to achieve the required site elevation, enhance drainage, or create a stable foundation for structures. It is particularly important when the native soil on site is insufficient for these needs.

Understanding the distinction between 'borrow' and other categories like 'fill' is crucial. While 'fill' generally refers to the material used to raise the ground level on a site, it does not specify the source. Therefore, 'borrow' specifically highlights the act of importing material from an external location. This precision in terminology is vital for effective communication in construction and landscape architecture.
