Gravel in Grundy County, TN

Local prices vary by material and supplier, but expect ballpark ranges: crushed limestone or #57 stone $30-$45/ton, crusher-run/DGA $20-$35/ton, pea gravel $30-$60/ton, and larger landscape rock $45-$75/ton. Many suppliers (including Hello Gravel partners) include free delivery in nearby areas or charge a delivery fee that effectively adds $0-$15/ton depending on distance and truck type.

For hilly ground, use a well-graded base like crusher-run or dense grade aggregate (DGA) topped with #57 or #67 crushed stone for a stable driving surface. In very steep or wet sections, larger angular stone (1u0022–2u0022) or a geotextile underlayment helps prevent tracking and rutting. Local geology on the Cumberland Plateau can vary, so confirm the exact stone type with your supplier.

Freeze-thaw and heavy rains on the Cumberland Plateau can cause rutting, washouts, and frost heave in gravel driveways. Good drainage—proper crown, swales, culverts, and regular regrading—greatly reduces damage. Expect periodic maintenance (regrading and topping) after severe weather rather than a one-time fix.

A 12 x 40 ft driveway (480 sq ft) needs about 4.4 cubic yards (roughly 6.2 tons) at a 3u0022 depth, about 5.9 cubic yards (8.3 tons) at 4u0022, and about 8.9 cubic yards (12.4 tons) at 6u0022. These figures use ~1.4 tons per cubic yard for crushed stone; add 10%–15% extra for compaction and waste and round up when ordering. Hello Gravel’s minimum order is 3 tons, so small areas may still meet the minimum.

Most local suppliers and Hello Gravel partners deliver gravel with tri-axle dump trucks; Hello Gravel’s platform has a 3-ton minimum order. Tailgate spreading may be offered by drivers at their discretion—request it at checkout, but don’t assume it’s guaranteed. Contact customer service or the supplier ahead of delivery if you need spreading or special placement instructions.

Crushed limestone is commonly available across much of Tennessee, but material can vary on the Cumberland Plateau (you may also see sandstone, chert, or mix blends). Crushed limestone is often recommended because its angular particles and fines lock together well for a stable surface and base. Always confirm with the local supplier which rock type you’re getting, since color and performance can vary regionally.

Use larger riprap or 2u0022+ rock at culverts and outlets, and 3/4u0022 crushed stone in swales and around drainage structures to slow flow and encourage infiltration. Combine stone with geotextile fabric under the rock and install check dams, bermed swales, or rock-lined channels to manage runoff on steep slopes. Vegetation and terraces paired with stone features help hold soil on the Cumberland Plateau’s slopes.

Gravel has a lower upfront cost—typical installed gravel can run roughly $1.00–$3.00 per sq ft—while asphalt and concrete are higher initially (asphalt ~$3.00–$7.00/sq ft, concrete ~$6.00–$12.00/sq ft). Gravel requires more frequent maintenance (grading, re-topping, and drainage repairs) especially with local rainfall and freeze-thaw cycles, while asphalt or concrete need less frequent routine care but higher repair costs if damaged. Choose based on budget, desired longevity, and how much maintenance you’ll do.

Grundy County may require a driveway permit, minimum culvert sizes, or sight-distance standards for new connections to county roads. Rules and requirements change, so contact the Grundy County Road Department or county office before work begins to confirm current specifications. Following county guidance early prevents rework and noncompliance delays.

Common options are geotextile fabric (separates soil from stone), cellular confinement grids (soil stabilization honeycomb), and polymer stabilizers that bind fines for a harder surface. Geotextile fabric typically adds a modest material cost—often a few dozen dollars to a few hundred dollars for a small driveway—while full systems (cellular confinement plus installation) can add $1.00–$3.00+ per sq ft installed. Polymer treatments and heavy stabilization systems cost more but reduce long-term maintenance; get local quotes because prices and effectiveness vary with site conditions.
