Fill Dirt in Cary, NC

Fill dirt is subsoil used to raise grade and fill holes; it contains little organic matter and focuses on volume and stability rather than fertility. In Cary, fill dirt is what contractors use to build up lawns, footings, or low spots before adding a thin layer of topsoil for planting.

A 1/4 acre is 10,890 sq ft; at 6 inches deep you need about 5,445 cubic feet (roughly 202 cubic yards) of fill dirt. Using a common rule of thumb of about 1.2 tons per cubic yard, that is approximately 240 tons, but get a supplier estimate because moisture and compaction change the final amount.

A common rule of thumb is about 1.2 tons per cubic yard for loose fill dirt, though weight varies with moisture and composition. For planning, multiply cubic yards by 1.1 to 1.4 to estimate tons and ask your Hello Gravel quote for a site-specific number.

Fill dirt can be used to raise grade under a driveway but is not a good final structural base on its own; a compacted crushed-stone base is recommended under pavement. For drainage swales, clean, well-graded fill can work to shape channels, but designers often specify free-draining material or engineered fill where runoff and erosion are concerns.

Cary sits in the Piedmont where clay content and heavy seasonal rains can cause shrink-swell behavior and slow drainage. That makes proper compaction, drainage planning, and sometimes mixing in coarser material important to reduce settlement and standing water after storms.

Many suppliers and haulers will offer tailgate spreading at the driver's discretion, but it is not guaranteed and usually limited. Dedicated compaction services are typically offered by local contractors, not by the delivery driver, so plan to rent a compactor or hire a landscaper if you need professional compaction.

When properly installed with good compaction and a suitable structural base, fill dirt under driveways and patios can be stable for many years, though some settlement in the first year is normal. Expect to monitor for minor settling after heavy rains and regrade or add material in low spots as needed.

Delivery fees vary by supplier, load size, and your exact Cary address; Hello Gravel shows transparent delivery pricing at checkout and many areas qualify for free delivery. Additional fees apply for next-day service, tailgate spreading requests, or hard-to-access drop locations; tipping (gratuity) for drivers is optional.

Small deliveries for routine lawn grading usually do not need a permit, but large earthwork that changes drainage, impacts wetlands, or exceeds local thresholds may require Town of Cary permits and erosion-control measures. Before large deliveries, check with Town of Cary Planning or Wake County for specific thresholds and stormwater rules.

Ask for 'clean fill' with minimal organic material, no construction debris, and a limited percentage of large rocks; contractors generally prefer material free of roots and trash. For engineered fills, request gradation reports or lab tests and specify maximum allowable organics and rock size so the material meets your project's needs.
