Fill-dirt in Pima, AZ

Prices vary by supplier, season, and truck delivery distance. In West Arizona rural areas like Pima, ballpark ranges are often about $10 to $25 per ton (roughly $8 to $18 per cubic yard), but prices can be outside that range.

Hello Gravel connects you with local suppliers and haulers who serve Pima, but exact suppliers depend on your zip code and current availability. Minimum order is generally 3 tons through our platform; trucks are typically tri-axle dump trucks (10 to 16 tons per load), and some suppliers also use smaller 5- to 10-yard trucks for tighter sites. Check your checkout options for supplier and truck-size details before you order.

Dry heat makes loose fill-dirt shrink, dust, and cake, while summer monsoon rains can cause rapid erosion or washouts if material is not compacted and graded. Proper compaction, slope control, and erosion measures (temporary berms, silt fences, or mulch) help keep fill-dirt stable year-round. For exposed surfaces consider a protective top layer like crushed rock or vegetation to reduce erosion during storms.

Quantities depend on area and depth; use cubic yards then convert to tons since density varies. Examples using 6 inches depth and a conversion around 1.4 tons per cubic yard: a 2-car driveway 20 ft x 20 ft at 6 inches needs about 7.4 cubic yards or about 10 tons. Yard grading 1,000 sq ft at 2 inches needs about 6.2 cubic yards (about 9 tons). For foundation backfill, calculate linear footage, height, and width, then convert to cubic yards and tons and confirm with our online calculator.

Contractors often use fill-dirt for raising grade and structural backfill, but prefer crusher run or decomposed granite as the driving surface because those materials compact better and shed water. Fill-dirt is good for bulk fill and subgrade work, while a mechanical, angular aggregate on top provides a more durable, dust-resistant driveway surface. If you want a finished driveway, ask your contractor about a layered approach: compacted fill-dirt base then a crushed rock or DG surface.

Remove vegetation and organic topsoil first, place fill in 4- to 6-inch lifts, and compact each lift with a plate compactor or roller until firm. Slight moisture helps compaction in dry Arizona conditions, but avoid over-wetting; consider geotextile fabric over very soft spots. For structural work, have a contractor perform a compaction test (percent of standard Proctor) and follow their specification for lift thickness and equipment.

Yes. Permits or approvals are often required for projects that affect drainage, septic systems, floodplains, or street grades. Check with your town and county planning or building department before placing large volumes of fill-dirt, and confirm septic setbacks and drainage requirements. If the project touches county roads or riparian/wash areas, get guidance from the local authority to avoid fines or rework.

Properly installed and compacted fill-dirt used as subgrade can last indefinitely, but surface settling and minor compaction changes are common in the first 1 to 3 years. Expect to regrade low spots, add small amounts of material, and maintain surface coverings like gravel or seed as needed. For driveways, the wearing surface (crusher run or DG) will need periodic replenishment and grading to control ruts and washboarding.

Yes. Local fill-dirt can include weed seeds, organic material, or job-site contaminants depending on the source. Ask suppliers through Hello Gravel whether the fill is screened, tested, or certified clean, and avoid using unvetted fill for sensitive sites like gardens, playgrounds, or near potable water lines. For landscaping, cover fill-dirt with clean topsoil or tested fill and consider solarization or composting before planting.

Blending a small amount of sand or fine crushed rock can improve drainage, while some clay content helps compaction but reduces drainage. For driveway subgrades, a structured mix of compactable fill-dirt under a layer of crusher run or decomposed granite gives the best balance of support and surface performance. Discuss project goals with your contractor or Hello Gravel sales team to choose a blend suited for drainage, compaction, and final surface needs.
