Fill Dirt in Duncan, OK

In Duncan and West Oklahoma, fill-dirt commonly ranges from about $8 to $18 per ton depending on quality and local supply. Delivery fees vary by distance and order size—many local deliveries are free or low-cost for larger loads, while smaller orders or longer hauls can add $50 to $150; Hello Gravel’s minimum order is 3 tons and standard delivery is 2+ business days.

Contractors in Duncan most often use screened fill (clean, weed-free soil) for yard grading and foundation backfill, clay-sand mixes where extra compaction is needed, and crushed rock or aggregate base as a cap for driveways. The choice depends on whether you need structural support (use engineered or crushed material) or just bulk raising/leveling (screened fill or common fill).

Duncan has hot summers and occasional freezes, so high-clay fill-dirt can shrink, crack, and heave with wet-dry and freeze-thaw cycles if not properly compacted and drained. Proper moisture control during placement and good surface drainage reduce settlement and long-term movement.

Large grading, substantial fill, or changes to site drainage often trigger local permits or erosion-control requirements from the City of Duncan or Stephens County. Requirements vary by project size and location; contact the Duncan building department and Stephens County planning office before major fills and inform Hello Gravel if permits are required so scheduling can account for inspections.

Fill-dirt typically weighs about 1.1 to 1.4 tons per cubic yard depending on moisture and compaction. For quick planning: a 1,000 sq ft area at 3 inches depth needs about 9 to 11 cubic yards (roughly 10 to 15 tons), and a 12'x100' driveway at 4 inches needs about 15 to 20 tons before compaction and capping.

Hello Gravel sources regionally from trusted suppliers around West Oklahoma; typical lead times are 2+ business days for standard delivery and next-day if ordered before noon CST (extra fee applies). For larger or custom-screened materials allow several days to a week, and always check availability for your zip code during busy seasons.

Local contractors place fill in lifts (typically 4 to 8 inches) and compact each lift with a plate compactor or roller, controlling moisture to reach good density. They also address soft spots with geotextile or crushed stone, slope for drainage, and use testing (compaction tests) on structural projects to meet building requirements.

Fill-dirt is for building grade and backfill but is usually poor for plant growth compared with topsoil, which contains organic material for landscaping. Engineered fill is specified and tested for structural loads, while crushed stone provides superior drainage and is the preferred cap for driveways; choose material based on whether you need stability, drainage, or planting quality.

Late spring through early fall is generally best in Duncan because soils are easier to work and less likely to be frozen or saturated. Avoid heavy rain seasons and days right after storms; schedule deliveries when you can grade and compact promptly to reduce washout or erosion risk.

A driveway built on compacted fill-dirt lasts longer if it has a proper crushed-stone base and routine maintenance; expect several years of service but longer-term performance depends on drainage, traffic, and climate. Minor repairs like regrading or spot re-compaction often cost $100 to $500, while resurfacing or adding new base material can run from $500 to a few thousand dollars depending on size and scope.
