Screened Fill Dirt (Clay Blend) is an economical, compactable soil material ideal for general grading, backfilling, and site preparation. This blend is sourced locally and screened at 3/8"minus to remove large debris, providing a smoother, more uniform texture for easy spreading and compaction. Its natural clay content enhances stability, making it excellent for use beneath lawns, driveways, patios, and retaining walls where firm subgrade support is essential.
 
Common Uses & Applications
Backfilling & Site Grading – Perfect for filling low spots, leveling uneven terrain, or establishing proper drainage grades before adding topsoil or turf.
Sub-Base Preparation – Used beneath concrete pads, pavers, patios, and driveways for added firmness and compaction.
Retaining Wall Backfill – Helps stabilize wall structures and prevent shifting by providing a compactable base layer.
Slope & Embankment Construction – Suitable for shaping landscape slopes and embankments where erosion resistance and soil strength are needed.
Utility Trenches & Foundations – Commonly used for filling trenches around pipes or structures once utility work is complete.

Frequently Asked Questions – Screened Fill Dirt (Clay Blend)
1. Is screened fill dirt the same as topsoil?
No. Screened fill dirt is a structural soil used for grading and base preparation. It has little to no organic matter, making it ideal for compaction — not for growing plants.
 
2. Can I plant directly into screened fill dirt?
It’s not recommended. For lawns, gardens, or landscaping, apply a 4–6″ layer of topsoil or planter mix over the fill dirt once grading is complete.
 
3. How much does a ton of fill dirt cover?
One cubic yard covers approximately 100 sq. ft. at 2″ deep or 60 sq. ft. at 4″ deep.
 
4. Is this material suitable for drainage?
Because it contains clay, it compacts tightly and is not ideal for drainage applications. Use drain rock or sandy backfill where water movement is required.
 
5. How is the screened fill dirt delivered?
All orders are delivered in bulk by small dump truck, directly to your driveway or project site. Drivers will dump where safely accessible and level.
 
6. What’s the best way to compact fill dirt?
Use a plate compactor or roller in thin layers (2–4″) for best results. Moistening the soil slightly before compacting improves density and stability.
