Fill Dirt in McFarland, CA

Fill dirt is generally cheaper than gravel in McFarland because it is usually untreated native soil with less processing. Final cost depends on local supply and haul distance, so delivery and minimum order (3 tons with Hello Gravel) can affect the per-ton price; request a quote for an exact price.

Fill dirt is mostly soil and fines used to raise elevations and fill voids; it may contain small rocks and organic matter and is not designed for drainage. Gravel is crushed rock or clean aggregate used for drainage, driveways, and load-bearing bases; it drains well and packs differently than fill dirt.

Volume depends on depth: at 4 inches (common for minor grade adjustments) 1,000 sq ft needs about 12.3 cubic yards, and at 6 inches needs about 18.5 cubic yards. That translates roughly to 15–18 tons for 4 inches and 22–26 tons for 6 inches depending on moisture and soil density; add about 10% for compaction and settling.

Typical tri-axle dump trucks used by our contractors commonly carry about 10–12 cubic yards of loose fill dirt, roughly 12–16 tons depending on moisture and material. Truck sizes vary by supplier, so confirm the truck type and exact yardage/weight when you get a quote from Hello Gravel.

A 20 ft by 50 ft driveway is 1,000 sq ft. For a 4-inch lift you would need about 12.3 cubic yards (roughly 15–18 tons); for a 6-inch lift about 18.5 cubic yards (roughly 22–26 tons). Remember that fill dirt is fine for raising grade but you should use compacted base aggregate for the driving surface and compact in lifts to reduce settlement.

You can place gravel over fill dirt, but the fill dirt must be properly prepared: remove vegetation and organics, compact the subgrade in lifts, and consider a geotextile or compacted base layer before laying driving gravel. In McFarland soils can include fines or clay that cause settling or poor drainage, so preparation prevents premature rutting or washout.

For drainage applications you should use clean, coarse gravel or crushed rock rather than fill dirt, because fill dirt contains fines that impede water flow. Use fill dirt to raise grades or fill voids, and use washed rock for French drains, dry wells, and areas where water must percolate; if McFarland's local soil is clayey, gravel is especially important for drainage.

All loose fill dirt will settle; time to stabilize depends on compaction and load. For landscaping or small grading work, compacted fill in 4–8 inch lifts and a short settling period is often sufficient, but for structures or driveways you should use engineered fill or a compaction spec and consult a geotechnical engineer to determine required compaction and wait times.
