Fill Dirt in Gillespie County, TX

Fill-dirt is bulk soil used to raise grade, fill low spots, and backfill foundations; it usually contains fines and small rock and is not intended as a finished surface. In Gillespie County’s Hill Country, use fill-dirt to level land, build pads, or raise septic/driveway elevations, but plan to cap it with compacted road base or crushed stone if you need a durable driveway or finished surface.

Delivered prices vary by supplier, distance, and site access, but expect roughly $15 to $35 per ton (about $20 to $45 per cubic yard) as a general range. Final price depends on haul distance into the Hill Country, load size, and any access fees; Hello Gravel’s minimum is 3 tons and delivery timing or next-day service may add fees.

Hello Gravel connects you with local quarries and haulers that serve Gillespie County and nearby Hill Country metros (Fredericksburg, Kerrville, Blanco). We recommend checking your zip code on our site to see available suppliers and requesting quotes that include delivery, site access notes, and any spreading services you might want.

Calculate cubic yards first: (length ft x width ft x depth in) / 324 = cubic yards, then multiply by about 1.2 to convert to tons for typical local fill-dirt. Add 5-10% extra for compaction and grading; for example, a 20 ft x 10 ft area at 6 inches deep is (20x10x6)/324 = 3.7 cubic yards (about 4.5 tons with allowance).

Gillespie County’s Hill Country soils often include shallow granite-derived soils and clay pockets that can cause uneven settlement and poor drainage. Intense rain events can cause erosion on slopes, so compact fill in lifts, protect slopes with erosion control (straw, silt fence, rock), and consider a geotechnical review for large fills or near structures.

For bulk raising and backfill, use screened, compactable fill-dirt (fines and small rock) to achieve good compaction; however, fill-dirt is not an ideal wearing surface. For driveways and erosion-prone slopes, place 4-8 inches of compacted road base or crushed limestone over compacted fill, and use larger rock or engineered riprap for active erosion control.

Plan for dump trucks to deliver, then use an excavator or skid steer to spread fill in 6-8 inch lifts and compact each lift with a vibratory plate or roller (sheepsfoot or small drum for deeper lifts). Remote sites may need temporary access roads, extra hauling charges, and crews experienced with Hill Country slopes; moisture conditioning the fill helps reach target compaction.

Possibly. Permitting depends on location (unincorporated county vs. city limits like Fredericksburg), project type, and proximity to floodplains or drainage easements; some HOAs have landscaping or visible alteration rules. Before ordering large deliveries, contact Gillespie County permitting or your city planning office and review HOA covenants to avoid fines or required rework.

Fill-dirt is economical for raising grade but does not compact or drain as well as road base or crushed limestone, so it will shorten driveway life if used as the finished surface. Road base or crushed limestone compacted to 4-8 inches provides strength and drainage; sand drains but can shift—best used only under engineered systems. For lasting driveways in the Hill Country, build a compacted fill subgrade, then add properly compacted road base and a wearing layer of crushed stone.

Mark the preferred drop location, clear a route for dump trucks, and note overhead wires or gates before delivery to avoid delays or extra fees. Request tailgate spreading at checkout if you want the driver to help (driver discretion applies), order 5-10% extra for compaction loss, and schedule deliveries outside heavy rain forecasts to limit erosion and hauling problems.
