Fill Dirt
Definition and meaning of Fill Dirt in real estate.
Fill dirt is subsoil that lacks organic matter, used in construction to raise ground levels, fill depressions, or stabilize foundations.
In more detail
Unlike topsoil, which contains organic nutrients that decompose and settle over time, this material is stable and does not shift significantly. Builders use it to create a sturdy base for foundations, driveways, and retaining walls. Home buyers and builders must verify that the material is compacted correctly to prevent structural settling or drainage problems later.
