Fill Dirt in Gallup, NM

Fill-dirt is clean, subsoil material used to raise ground elevations or fill voids; it usually contains less organic matter than topsoil. In Gallup's high-desert environment, fill-dirt is a good choice for leveling, backfilling, and building pads where weed growth and drainage are concerns, but it is not suited for planting beds or final landscaping that needs fertile soil.

Local prices vary, but expect roughly $10 to $30 per ton for basic fill-dirt in the Gallup area, which converts to about $13 to $40 per cubic yard depending on moisture and compaction. Final price depends on supplier, delivery distance, required hauling permits, and whether you need spreading or extra handling.

A typical 2-car driveway (about 20 ft by 20 ft) at 3 inches of fill needs roughly 3.5 to 5 cubic yards, or about 4.5 to 6.5 tons of fill-dirt after accounting for loose versus compacted material. If you plan deeper buildup, subgrade correction, or compaction, order 10% to 20% extra to cover settling and spread loss.

A 30 ft by 30 ft pad at 6 inches of fill is about 16.7 cubic yards, which is roughly 20 to 25 tons of fill-dirt depending on moisture and local material density. For structural pads you should add 10% to 20% extra for compaction, grading waste, and to ensure final elevations.

Gallup sits in a high-desert zone with sandy-clay native soils, low organic content, and large daily temperature swings at higher elevation, which can increase freeze-thaw movement. Monsoon rains can cause short periods of erosion or washing if fill is not compacted and drained properly, so plan for good slope, drainage, and compaction when using fill-dirt here.

Contractors in the Gallup area typically place fill-dirt in 4- to 6-inch lifts and compact each lift mechanically to reduce settling; moisture conditioning before compaction improves results. Maintain good surface drainage, regrade low spots after heavy rain, and avoid using untreated fill-dirt as a finished driving surface without a proper wearing layer like crusher run or road base.

Yes. Gallup's regional suppliers may be farther away than urban centers, which can raise delivery fees and scheduling time. Hello Gravel typically requires a minimum order of 3 tons, delivers by dump truck (tri-axles are common), and offers standard delivery in 2+ business days with next-day options if ordered before the cutoff; narrow driveways, overhead lines, and steep access can limit where trucks can dump.

Local contractors often recommend road base or crusher run for driveways because those materials compact better and create a more stable surface under traffic, while decomposed granite is chosen for decorative, low-traffic paths. For structural foundation work, engineered fill or compacted gravel base is typically preferred over untreated fill-dirt.

Permit needs depend on the project: building pads, structures, and septic systems often require county permits or inspections in McKinley County, while simple grading or small driveway repairs may not. Always check with the Gallup city planning or McKinley County building department before ordering large quantities if your project involves foundations, septic systems, or changes to drainage.

Homeowners in Gallup source fill-dirt from local quarries, dirt suppliers, and online marketplaces like Hello Gravel that connect to regional haulers. When choosing a supplier, ask for a material description (clean subsoil vs. topsoil), delivery terms, photos if available, references, and whether the driver can tailgate-spread at their discretion; request a written quote that includes delivery so you can compare total cost.
