Fill Dirt in Research Triangle Park, NC

Typical delivered prices for fill dirt in the Research Triangle Park area usually range from about $15 to $35 per cubic yard (roughly $12 to $28 per ton), depending on moisture, density, and whether it is screened or 'select' fill. Final pricing depends on supplier, distance, and order size; use our zip-code lookup or request a quote for an exact delivered price.

Hello Gravel commonly offers free delivery in many areas, but small orders, tight access, or long haul distances can add a delivery fee (often $30-$150). Trucks are usually tri-axle dump trucks that need street access, about 12 to 14 feet of turning width, and a safe place to dump; narrow drives, overhead wires, cul-de-sacs, or weight-restricted streets may require offloading farther away or a smaller truck and additional charges.

For the Piedmont clay common around RTP, choose a low-organic, granular 'select' or structural fill that includes some sand or coarse material to limit shrink-swell and improve drainage; avoid using topsoil or high-organic materials as fill. For paved driveways, place compactable fill in lifts and finish with a compacted base (crushed stone) before surfacing; speak with your contractor or use Hello Gravel notes to request a blend suited to your application.

RTP gets wet springs and fall rains that make native Piedmont clay sticky and hard to compact when too wet, so schedule deliveries and compaction in drier windows when possible. Contractors compact in lifts with mechanical equipment and may need to delay work after heavy rain; also plan for a short settling period and allow extra material for minor settlement.

Contractors commonly place fill in 4-8 inch lifts and compact each lift with a plate compactor or small vibratory roller for residential work; stabilization can include adding sand or geotextile fabric where needed. Typical costs vary by job size and access but often range from about $0.50 to $2.00 per square foot for grading and compaction on small residential sites, or contractors may charge hourly rates ($50-$150/hour) for equipment and operator; get local bids for exact pricing.

To raise 1,000 sq ft by 6 inches you need 500 cubic feet, which equals about 18.5 cubic yards (500/27). Depending on moisture and compaction that is roughly 20 to 25 tons of fill dirt; we recommend ordering 5-10% extra to allow for settlement and minor grade adjustments.

Next-day delivery is often available if you place the order before the cutoff (note: Hello Gravel's published next-day cutoff is before noon CST) and local supplier capacity allows, but same-day service is less common and depends on supplier and truck availability. Use the Hello Gravel checkout to check zip-code availability and request expedited delivery or call our team for the fastest local options.

Large deliveries that block a public street, require cranes, or change drainage/grades may require city or county permits and many HOAs have rules about exterior work or visible stockpiles, so check with Durham/Chapel Hill/RTP-area local authorities and your HOA before ordering. Suppliers and haulers typically provide delivery tickets and weight tickets but usually do not file permits on your behalf, so plan to handle approvals or hire a contractor who will.

Ask for 'clean' or 'select' fill (not topsoil) and specify if you need screened or rock-free material; note that regional color and texture can vary due to local geology. Reserve a delivery window during a dry forecast, request tailgate spreading at checkout understanding it is at the driver's discretion, and contact our team with site photos or access notes to help suppliers estimate fees and truck choices.
