Fill Dirt in Modesto, CA

Fill dirt is subsoil used to raise or level ground; it is mostly fine particles with little organic matter. Gravel is crushed rock or rounded stone used for drainage and surface cover. In Modesto, fill dirt is commonly used to build up grades, while gravel is used for driveways, drainage, and erosion control.

Fill dirt is generally cheaper per cubic yard than crushed gravel because it is lower-spec material and often locally available from excavations. Prices in Modesto still vary by supplier, truck distance, and quality, so check Hello Gravel for an accurate quote and delivery price for your zip code.

Yes — fill dirt is commonly used to raise low spots and create rough grades. For lawns or gardens in Modesto's clay-prone soil, place 2–4 inches of topsoil or a mix of compost over the compacted fill dirt before planting to support grass and plants.

Not reliably. Fill dirt lacks organic matter and nutrients that grass needs, so you should add topsoil or amend the surface with compost before seeding. In Modesto's hot, dry summers, improved surface soil and irrigation will help new grass establish.

Alternatives include structural engineered fill (compacted clean fill), recycled concrete aggregate (for structural or drainage uses), and clean sand for specific drainage or bedding needs. Choose the alternative based on your project: use structural fill for building pads and topsoil/compost for planting surfaces.

Multiply area by depth to get cubic feet, then divide by 27 for cubic yards. For example, 1,000 sq ft at 6 inches deep = 1,000 x 0.5 ft = 500 cu ft ÷ 27 = about 18.5 cubic yards. Use Hello Gravel's material calculator for quick estimates and to convert to tons and truck loads for Modesto deliveries.

Costs vary by supplier, distance, and material quality. As a ballpark estimate, delivered fill dirt in the Modesto area commonly ranges from about $15 to $40 per cubic yard; a single tri-axle load (roughly 10–14 cubic yards) could therefore cost several hundred dollars.

A typical tri-axle dump truck commonly used in the area carries about 10–14 cubic yards of loose material. Fill dirt weighs more when wet or compacted (roughly 1.2–1.4 tons per cubic yard depending on moisture), so a truckload can equal roughly 12–20 tons. Hello Gravel has a 3-ton minimum order, and our checkout shows truck-sizing and delivery options for Modesto.

You can place gravel over compacted fill dirt, but the base must be properly graded and compacted to avoid settling. In Modesto, where soils can be clayey and expand with moisture, compacting the fill and using a geotextile or crushed rock base will give a more stable surface and reduce long-term sinking.

Yes — gravel is commonly used in drainage solutions like French drains and dry wells because it promotes water flow. Fill dirt is used to raise or fill areas, not for drainage, so use clean gravel or aggregate with a perforated pipe for effective subsurface drainage in Modesto yards.

Stabilize fill dirt by compacting it in 4–6 inch lifts with a mechanical compactor, installing proper drainage, and using erosion control (straw, mulch, or erosion mat) on exposed slopes. For driveways and building pads in Modesto, consider adding crushed rock base and geotextile fabric and, if required, consult a geotechnical recommendation for deeper fills.

Some big-box stores sell bagged soil and may offer bulk dirt delivery in limited areas, but their bulk availability and minimums vary. For larger projects in Modesto, Hello Gravel connects you with local suppliers and dump truck delivery with a clearer bulk pricing and scheduling process.

The 70/30 rule typically refers to mixing 70% topsoil with 30% compost for planting mixes; it is not a recipe for fill dirt. Fill dirt should be used for grading and subgrade work, while the 70/30 topsoil/compost mix is appropriate for growing lawns, gardens, and planting beds in Modesto.

Buy local fill dirt in bulk (Hello Gravel has a 3-ton minimum) and spread it in shallow lifts, compacting each layer to reduce future settling. After achieving grade, cap the area with 2–4 inches of topsoil where you plan to plant; this approach balances cost and long-term performance in Modesto's climate.
