Fill dirt, also known as unscreened fill, bulk fill soil, construction fill, or common fill, is a natural earth material used for large-volume filling, rough grading, and site preparation. It is typically excavated directly from the ground and may contain a natural blend of soil, sand, clay, small stones, roots, and organic particles.
Its substantial texture and economical cost make fill dirt a practical choice for building up low areas, reshaping uneven ground, and raising site elevations before finished materials are installed. When properly placed and compacted in layers, it helps create a stable foundation for future landscaping, driveways, building pads, pavement, and other site improvements.
Fill dirt is widely used in residential, commercial, agricultural, and construction projects because it provides efficient bulk coverage for large areas. It is commonly installed beneath screened topsoil, gravel, asphalt, concrete, or other finished surfaces to establish the required grade and prepare the site for the next phase of work.
