Fill-dirt in Aurora, CO

Fill dirt is clean, natural soil used to raise or level ground—usually free of organic material like roots. In Aurora, it is commonly used for backyard leveling, building up low spots, backfilling foundations, and preparing sites before installing a gravel base or sod. Because the Denver-Aurora area has freeze-thaw cycles, proper compaction and drainage are important after placement.

Typical material-only prices in the Aurora/Denver area are roughly $8 to $20 per cubic yard and about $6 to $15 per ton, though regional supply and moisture content can push prices higher. One cubic yard of fill dirt usually weighs about 1.2 to 1.4 tons, so your actual per-ton cost will depend on the delivered moisture and compaction. Final price also depends on delivery, minimum order, and any site access or spreading requests.

Hello Gravel’s minimum order is 3 tons, and many orders in the metro area qualify for free standard delivery; however, delivery fees for 10–20 yard loads commonly range from $0 to $200 depending on supplier distance, site access, and requested delivery date. Larger loads usually lower the per-yard delivery cost, but tight access, soft driveways, or narrow streets can add fees. Always check your zip code in checkout and request a delivery window or tailgate spreading if needed.

Use this quick guide for 1,000 sq ft: 2u0022 depth ≈ 6.2 cubic yards (≈ 8.0 tons), 4u0022 depth ≈ 12.4 cubic yards (≈ 16.1 tons), 6u0022 depth ≈ 18.5 cubic yards (≈ 24.1 tons). These are approximate; one cubic yard is about 1.2–1.4 tons depending on moisture and composition. For finish grading or to allow for settling, add 5–10% extra.

Costs depend on driveway width and depth; assuming a single-car driveway 10' wide by 20' long (200 sq ft): a 6u0022 base needs about 3.7 cubic yards. Using fill dirt as a cheap raise will cost less in material (roughly $30–$150 material plus delivery) but will require compaction and may settle more over time. A proper compacted crushed-rock base (recommended for driveways) typically uses 3–5 cubic yards of base rock and costs more in materials and compaction (typical combined materials, delivery, and compaction labor often ranges from $400 to $1,500 in the Aurora area). For driveways we recommend a compacted gravel base over loose fill dirt for long-term stability.

Yes, small amounts of fill dirt can be placed over existing soil to level low spots, but preparation is important: remove vegetation and large debris, regrade to promote drainage, and place fill in 4–6u0022 lifts with compaction between lifts. In Aurora’s freeze-thaw environment, compaction and proper slope (typically 1–2% away from structures) help prevent settling and frost heave. For large fills or poor native soils, adding geotextile fabric or compacted structural fill may be recommended.

Putting gravel directly over unconsolidated dirt in Aurora’s soils often leads to migration, rutting, and frost-related heaving. If you plan to use gravel, place compacted fill dirt in lifts, then a layer of compacted crushed rock (4u0022 or more) as a stable base, and consider geotextile fabric to reduce mixing with underlying soil. When ordering fill dirt, consider adding crushed rock for the final base, compaction services, and specifying drainage improvements to improve long-term performance.

Fill dirt is almost always cheaper and more practical in bulk. A 50 lb bag is only about 0.02 cubic yards, so one cubic yard equals roughly 50–55 bags. For any project over about 2–3 cubic yards (small yard patches) you’ll save time and money by ordering bulk.

Fill dirt can settle, especially if organic material or roots are present, so you may need to top-up or regrade in the first year or two. Poorly drained fills can contribute to puddling and frost heave during winter, so plan for compaction and proper slopes. Expect occasional added costs for topping up, reseeding, erosion control, or installing edging and drainage if the area is high-traffic or exposed to runoff.

Yes. Large fills or projects that change site grading or stormwater runoff can trigger local permits from the City of Aurora or county agencies and may require drainage plans or erosion controls. HOAs often have rules about grading, visible changes, or material types; check your HOA covenants and contact city planning before major earthwork. If in doubt, contact our sales team and your local permitting office to confirm requirements before ordering.
