Fill Dirt in Campo, CA

Yes, fill dirt is generally cheaper than crushed gravel because it is usually composed of native soil and small rock rather than processed stone. In Campo you can expect lower per-ton and per-cubic-yard costs for fill dirt, though exact prices vary by supplier, season, and hauling distance. Hello Gravel requires a 3-ton minimum order and can provide a local quote for the most accurate price.

Fill dirt is mostly subsoil, clay, sand, and small rock used to raise grades or fill voids; it is not intended as a decorative or draining surface. Gravel is crushed rock or rounded stone designed for drainage, traction, and finished surfaces. In Campo, fill dirt is commonly used to build up low spots before finishing with gravel or topsoil.

Use a compacted layer of fill dirt as the subbase, then install a geotextile filter fabric to prevent soils from mixing with the gravel. The fabric keeps the gravel draining properly and reduces contamination from Campo's sandy or silty native soils. For steep or wet areas, add a compacted crushed stone layer before the top gravel for extra stability.

Costs vary with supplier and haul distance, but a typical tri-axle truckload of loose fill dirt in Southern California often falls into a broad range. For an accurate number in Campo, request a quote through Hello Gravel; we’ll provide local pricing and delivery details based on your zip code and required volume. Remember our minimum order is 3 tons.

Volume depends on depth: at 2 inches depth 1,000 sq ft needs about 6.2 cubic yards (roughly 7–8 tons), at 4 inches it needs about 12.3 cubic yards (roughly 15–16 tons). Use the formula: cubic yards = area (sq ft) x depth (ft) / 27, then multiply by the local tons-per-cubic-yard factor (about 1.2–1.4 tons/cu yd for fill dirt). Contact Hello Gravel for a site-specific estimate for Campo.

Measure length and desired base depth, then use the volume formula. For example, a 20 ft wide by 100 ft long driveway at a 3-inch base needs about 18.5 cubic yards, roughly 22–26 tons of fill dirt depending on compaction. If you need help converting dimensions or choosing depth, Hello Gravel’s calculator and sales team can assist.

Not recommended without preparation. You should compact the fill dirt, install a geotextile fabric, and add a proper crushed-stone base before placing surface gravel so the gravel does not mix with or sink into the fill. In Campo’s variable soils and occasional heavy rain events, this prep prevents rutting and erosion.

Yes — for drainage purposes use clean, washed drain rock or 3/4-inch crushed rock, not fill dirt, which tends to hold water and can clog drains. Line the hole with filter fabric, add rock to the design depth, and top with a layer of coarse sand if needed to prevent fines from migrating. In Campo, this approach helps manage runoff during winter storms and keeps soil from washing into the rock.

A 50 lb bag contains 50 pounds, so you need about 50–55 bags to equal one cubic yard of fill dirt (depending on density). Since one cubic yard of fill dirt is roughly 1.2–1.4 tons, a typical tri-axle load (several cubic yards) would equal hundreds of 50 lb bags, so bulk delivery through Hello Gravel is usually much more economical for projects in Campo.

The 70/30 rule typically refers to mixing about 70% topsoil with 30% compost for garden beds to improve fertility and drainage. Fill dirt is not a substitute for topsoil because it usually lacks organic matter and nutrients, so you should not use it as your final planting surface in Campo. If you must use fill dirt to raise grades, cap it with at least 4–6 inches of topsoil or a topsoil-compost mix before planting.

No — loose fill dirt will settle unevenly over time, causing dips and instability. For driveways, foundations, or any structural grade work in Campo, place fill in thin lifts and compact each layer to the required density to reduce future settling. If you are unsure about compaction requirements, consult a local contractor or the Hello Gravel team for guidance.

Start with the area and depth to get cubic yards (area x depth / 27), then multiply by a local conversion factor (about 1.2–1.4 tons per cubic yard for fill dirt) to estimate tons. Hello Gravel has a 3-ton minimum order; we’ll verify final tonnage, truck size, and delivery window for Campo when you request a quote.
