Fill Dirt in Fontana, CA

Prices for fill dirt in Fontana vary by supplier, load size, and exact material; use Hello Gravel to get real-time local quotes for your zip code. Hello Gravel has a 3-ton minimum order and delivery fees depend on distance, access, and whether special offloading is needed. Standard delivery is typically 2+ business days, and next-day options may be available for an extra fee if a local supplier and hauler have capacity.

Same-day delivery is possible but depends on local supplier and truck availability, so check Hello Gravel for live availability. Most dump-truck suppliers deliver material only; compaction and mechanical compaction services are usually provided by local contractors rather than the material hauler. If you need compaction, ask Hello Gravel to coordinate a contractor or request referrals to local graders and compacting crews.

Fontana and the Inland Empire commonly have clay and expansive soil zones that hold moisture and change volume with wetting and drying. Plain fill dirt placed without proper compaction and drainage can settle, heave, or retain water, causing problems for yards, driveways, and foundations. For any load-bearing use, use engineered fill or proper subgrade preparation with tested compaction to reduce long-term movement.

Use 27 cubic feet per cubic yard to estimate coverage: 1 cubic yard covers 81 sq ft at 4 inches, 54 sq ft at 6 inches, and 27 sq ft at 12 inches. Fill dirt typically weighs about 1.2 to 1.4 tons per cubic yard, so multiply cubic yards by that range to get tons and add 5 to 10 percent for compaction and settlement. Example: a 1,000 sq ft area at 6 inches needs about 18.5 cubic yards (about 22 to 26 tons) before compaction.

Permits and testing requirements depend on the project scope: small landscaping fills usually do not need a permit, but grading, structural fills, foundations, and retaining walls often require permits, compaction reports, and sometimes soil testing. Always check with the City of Fontana Building and Safety Division or San Bernardino County for project-specific thresholds and documentation requirements. If your project is near property lines, affects drainage, or changes grade more than a few inches, plan to contact the building department first.

Fill dirt is usually the cheapest option for raising grade but is not engineered for structural support and can retain water and settle. Engineered fill is specified, placed, and tested to meet structural requirements and is the right choice under foundations and load-bearing walls. Decomposed granite is decorative and drains well but is not a structural base; crushed rock or crushed stone is commonly used for driveways and bases because it compacts well and provides good drainage.

Hello Gravel has a minimum order of 3 tons; deliveries are typically made with tri-axle dump trucks. Trucks generally need clear overhead clearance (about 12 to 14 feet), a 20 to 30 foot turning/backing zone, and reasonably firm ground; narrow lanes, soft lawns, or tight alleys can trigger extra labor or equipment fees. Drivers may perform tailgate spreading at their discretion, but additional offloading or manpower fees can apply for difficult access or small, specialized requests.

Fill dirt used as general grade material can last indefinitely for non-structural uses, but it will settle over time, especially in areas with clay soils and seasonal rains; expect initial settlement in the first year. For driveways and high-traffic surfaces, fill dirt alone is not durable; you will need a compacted base of engineered material and a wearing surface such as crushed rock or pavement. Typical maintenance includes adding and regrading soil after settlement, maintaining drainage, and controlling erosion with vegetation or hardscapes.

Yes. Compacted clay-rich fill can increase runoff and concentrate water flow, which can cause erosion and violate local stormwater or grading rules. Fontana has stormwater and erosion-control requirements for construction and grading work, so use swales, terraces, permeable surfaces, or erosion-control blankets as needed and check permit conditions. For any project that changes grade or disturbs soil, review local stormwater rules and plan to control runoff during and after work.

Many local grading and landscaping contractors in Fontana handle fill dirt installation, compaction, and related site prep; Hello Gravel can help connect you with haulers and often refer contractors experienced with compaction. Typical service packages include site grading, mechanical compaction with rollers or plate compactors, moisture conditioning, final grading, and sometimes compaction testing and certification for structural work. When hiring, ask for proof of equipment, compaction test reports if needed, and references for similar local projects.
