Fill Dirt in Gilroy, CA

Fill dirt is clean subsoil used to raise or level ground and is not intended as a finished surface; gravel is crushed rock used for driveways and surface drainage. For a driveway surface in Gilroy, choose gravel (with a proper base) because fill dirt will rut and hold water. Fill dirt is usually cheaper per cubic yard than decorative gravel, but because it compacts and can be heavier, delivery and compaction costs can narrow that difference; check our quote for zip-code-specific pricing.

A typical tri-axle dump truck carries about 10 to 14 cubic yards of fill dirt, roughly 14 to 20 tons depending on moisture and soil type. Delivered prices in the Gilroy area vary by supplier, distance, and material quality; expect a wide range, so get a Hello Gravel quote for an exact price — remember our minimum order is 3 tons and standard delivery takes 2+ business days.

Covering 1,000 sq ft requires about 6.2 yd3 at 2u0022, 9.3 yd3 at 3u0022, and 12.3 yd3 at 4u0022. Because local suppliers and delivery distance affect pricing, costs can vary; use Hello Gravel’s calculator or request a quote for exact material plus delivery costs for your Gilroy address. Keep in mind fill dirt is intended for grade raising, not finished surfacing, and additional compaction or topsoil may be needed.

For simple raising or backfilling, fill dirt is the most economical material per cubic yard in many cases, but for a driveway surface you still need a gravel base and topping for durability. A 20-ft wide driveway length affects volume — for example, raising a 20 x 30 ft area by 3u0022 needs about 3.3 yd3; for accurate pricing get a Hello Gravel quote because local hauling and supplier rates determine the final cost. Also factor in compaction and possible import of base rock if you want a lasting driving surface.

Yes, you can add fill dirt over existing soil to raise grade, but you should remove unsuitable materials (organic topsoil, roots) and add fill in thin lifts with compaction to avoid future settling. In Gilroy’s varied soils, poorly draining or high-clay layers may require a granular base or geotextile if you intend to build a driveway or structure on top. For landscaping grade adjustments only, adding and compacting fill dirt in layers usually suffices; for structural work, consult a contractor and include a base and proper compaction.

Fill dirt should not be used as the finished driveway surface, so 2 inches is not appropriate for driving surfaces. For raising a grade before installing a driveway, thin lifts of fill dirt (2 to 4 inches per lift) with compaction are common, but the finished gravel or asphalt surface typically needs several inches of compacted base rock plus a 2 to 4 inch wearing layer. For a long-lasting driveway in Gilroy, plan for a compacted base (4 to 8 inches of aggregate base) and a top layer suited to your surface choice.

Fill dirt can be used to raise and level a backyard, especially under lawns or hardscapes; calculate volume using area x depth/27 to get cubic yards and then order with Hello Gravel’s calculator. If you need a plant-friendly surface or better drainage, screened topsoil or a mix of topsoil over compacted fill dirt is often a better choice than raw fill dirt alone, because Gilroy soils can be clayey and slow-draining. For drainage-sensitive areas, consider engineered fill, sand, or installing drainage rock instead of relying solely on fill dirt.

No — fill dirt is fine-grained and tends to reduce drainage, so it is not suitable for creating a drainage layer. For drainage applications in Gilroy, use clean, coarse gravel or drainage rock (3/4u0022 to 1-1/2u0022 minus depending on the use) and landscape fabric to keep fines out of the rock. Order gravel or drainage rock through Hello Gravel and request delivery size that matches the hole or trench dimensions.

Fill dirt cannot be made to harden like concrete; it is used for filling and grading only. Durable surfaces that lock up include crusher run, aggregate base, or polymer-stabilized mixes and these are the materials to order if you want a hard, driving surface. Use Hello Gravel to see local options like crusher run or stabilizer blends available near Gilroy and ask about delivery and spreading options.

A 20 x 20 ft pad at 6 inches deep requires about 7.4 cubic yards of material, which is roughly 10 to 11 tons of fill dirt depending on moisture and soil density. Delivery cost depends on supplier, haul distance, and order size; contact Hello Gravel for a zip-code-specific quote and remember our minimum order is 3 tons and standard delivery is 2+ business days. If the pad needs compaction or a structural base, include aggregate base rock in your plan rather than only fill dirt.
