Backfill
Backfill refers to the process of putting soil or other materials back into a hole or trench after construction work is done. Think of it like filling in a hole in your garden, but on a much bigger scale for construction projects. This is a crucial step in construction because it provides support for foundations, pipes, or structures that have been installed. The material used for backfill needs to be carefully selected and properly compacted to prevent future settling or structural problems. When someone mentions backfill in their resume, they're typically talking about their experience with this important construction finishing process.
