What is another term for soil that is transported and used as fill material?

The term "borrow" refers specifically to soil or earth material that is excavated from one location and transported to another site for use as fill material. This practice is common in construction, engineering, and landscaping projects where there is a need to raise the ground level or create a stable foundation. The term emphasizes the temporary nature of obtaining the material, as it suggests taking soil from one area to benefit another.

Other terms such as "placement" generally refer to the act of putting the material in its designated location, while "overlay" can imply covering a surface with material rather than transporting it from elsewhere. "Burden," on the other hand, does not specifically pertain to soil and is more often associated with the weight or load carried by something. Thus, "borrow" accurately captures the process of sourcing soil for fill purposes.
