Fill Dirt in Irvine, CA

Delivered fill dirt prices in Irvine commonly fall into a range because of supplier, distance, and volume; expect roughly $15 to $45 per ton (or about $20 to $60 per cubic yard) as a general ballpark. Final price depends on your zip code, minimum order (Hello Gravel minimum is 3 tons), delivery access, and whether you need spreading or compaction. Use our zip-code checkout or contact our team for an exact quote.

Suppliers include local landscape & aggregate yards, construction material dealers, and grading contractors; Hello Gravel connects you with trusted local suppliers and contracted dump truck haulers in the Irvine area. For compaction and grading, look for local grading contractors, civil contractors, or landscape installers; many suppliers or contractors will bundle delivery and compaction or refer you to a compaction specialist. If you want turnkey service, request delivery plus compaction when you get a quote so we can match you with vendors who offer both.

Permit needs depend on scope: small landscaping fills and minor low-height grading often do not need a permit, but any structural grading, retaining walls, alterations to drainage, or large volume fills typically require permits or review by City of Irvine or Orange County. Always check with the City of Irvine Planning & Building or Orange County Public Works before major grading, driveway expansions, or changes affecting runoff, and pull required permits for work near property lines or environmental-sensitive areas. If in doubt, contact the local building department or your contractor for guidance.

For structural work like slabs and driveways, aim for 90% to 95% of the maximum dry density (per local geotech/engineer guidance); 95% is common for driveways and structural slabs, while 90% may be acceptable for non-structural landscaping. Place fill dirt in 4- to 8-inch lifts, control moisture, and compact each lift with the appropriate equipment (plate compactor for small areas, vibratory roller for larger lifts). For foundations or engineered projects, follow a geotechnical report or engineer specifications.

Use volume math: cubic yards = (length x width x depth in feet) / 27. Example 1: 10 ft x 10 ft x 6 in (0.5 ft) = 50 ft3 = 1.85 cubic yards, which typically equals about 2.2 tons loose and 2.6 tons compacted using common estimates (loose ~1.2 tons/yd3, compacted ~1.4 tons/yd3). Example 2: 20 ft x 20 ft x 1 ft = 400 ft3 = 14.8 cubic yards, roughly 17.8 tons loose and 20.7 tons compacted; always add 10% to 20% for compaction and waste and check with your supplier for local density assumptions.

Fill dirt is generally not ideal where drainage and erosion control are primary concerns because it often contains fines that hold water and can weaken slopes. For drainage and erosion control on slopes, use engineered fill mixes, clean rock layers, crushed stone, or geotextile systems and pair them with proper drainage features (French drains, subdrains) and erosion control blankets or vegetation. Consult a civil or geotechnical engineer for slope work in Irvine, especially on coastal or steep sites.

Fill dirt is mostly soil and fines and is intended to raise grade or backfill, not as a structural base. Crusher run and road base are engineered mixes of crushed rock and fines designed to compact into a strong base for driveways and paving; decomposed granite is a finer, decorative, and permeable option for paths and patios but needs stabilizer for heavy use. For driveways and under pavers or slabs, choose crusher run or road base under a wearing surface rather than plain fill dirt.

If properly compacted and graded, fill dirt bases can perform well, but poorly compacted fill will settle, causing low spots and drainage issues after heavy rain events. In Southern California, occasional intense storms can cause erosion on unprotected slopes or unfinished areas, so you may need periodic regrading, erosion control, and good surface drainage. Proper initial compaction, vegetation, or surface stabilization significantly reduces long-term maintenance.

Hello Gravel commonly uses tri-axle dump trucks for deliveries; a tri-axle load typically carries about 10 to 14 cubic yards (varies by truck and local weight limits). Hello Gravel's minimum order is 3 tons; delivery fees depend on location, access, and quantity—many areas offer free delivery, while remote or tight-access sites may incur an extra fee. Standard delivery timing is 2+ business days, with next-day available for orders placed before noon CST for an added fee.

For paver bases, use a compacted road base or 3/4u0022 crusher run topped with a 1u0022 sand bedding layer rather than straight fill dirt. Under-slab backfill should be engineered fill or compactible sand/aggregate per your engineer or geotechnical report; avoid organic topsoil or loose fill directly under slabs. For general landscaping, mixing fill dirt with some clean sand or crushed rock can improve drainage and compaction—ask your supplier for local mix options.

Place fill dirt in thin lifts (typically 4 to 8 inches), control moisture to near-optimum for compaction, and compact each lift before adding the next. Avoid dumping deep piles and trying to compact them in one pass; for tight or small spaces use plate compactors and for larger areas use vibratory rollers. Keep material away from building foundations until inspected and follow your permit or geotech guidance.

Because Hello Gravel sources materials regionally, fill dirt appearance, texture, and color vary with local geology and processing methods, so samples or photos may differ from what arrives. You can add color or texture preferences in the Order Notes at checkout and we will try to match requests, but exact matches cannot be guaranteed. If an exact material spec is critical, request a sample or ask our team for supplier-specific details before ordering.
