Clean fill dirt is soil made mostly of clay, rock, and sand — and free from trash, contaminants, or organic material. It’s ideal for leveling your yard, backfilling near foundations, or building up low spots. It’s not suitable for planting, but it’s a stable, affordable way to reshape your property. You can post what you need or offer excess dirt for free using tools like DirtMatch — a free marketplace that connects homeowners and contractors locally.
What Makes Dirt “Clean”?
- No paint, concrete, glass, or asphalt
- No organic debris (grass, roots, mulch)

- Consistent composition — usually clay-heavy or sandy
- May be certified or tested, depending on your location
When Should You Use Clean Fill Dirt?
- Fill a hole or trench
- Level out a lawn or build a slope
- Raise land for a patio, shed, or retaining wall
- Backfill around foundations or driveways
- Fix drainage by shaping terrain

Common Questions About Clean Fill
- Do I need a permit to bring in fill?
Maybe. In some cities or counties, permits are required for large quantities, near creeks, or when changing grades. - Can I plant on clean fill dirt?
Not directly. It lacks nutrients and can compact heavily. Add 4–6 inches of topsoil on top before planting. - How much does clean fill cost?
Sometimes free (especially if you pick it up). Delivery costs will vary depending on yardage and distance.
