Fill dirt is the term used to describe any type of soil or earth material that is used to fill a hole, level the ground, or raise the elevation of a property. It’s an important component of many construction projects, including the building of new homes. Fill dirt, also known as backfill, is typically sourced from a variety of locations, including excavation sites, construction projects, and agricultural fields. It’s important to note that not all fill dirt is created equal. The quality of the soil can vary greatly depending on its composition, moisture content, and other factors. This means that not all fill dirt is suitable for use in construction projects.
