Gravel in Helena, MT

Delivered prices vary by type and season; expect roughly $35-$60 per ton for common crushed gravel delivered to the Helena area, with landscape or decorative rock often costing more. One cubic yard of typical gravel weighs about 1.4 tons, so convert prices using that factor. Prices often rise in late fall and winter (fuel and access issues) and during peak spring landscaping season, and Hello Gravel’s minimum order is 3 tons so small jobs may need that minimum.

Common local materials include crushed 3/4u0022 minus (well-graded, compactable), 3/8u0022 and 1/4u0022 fines mixes, pea gravel, river rock, and 1u0022-2u0022 clean drain rock. For Helena driveways choose angular crushed rock (3/4u0022 minus or 3/8u0022 minus) for compaction and traction; patios typically use a compactable base such as 3/8u0022 minus or crushed fines topped with pea gravel or decomposed granite for appearance; drainage swales and French drains use 1u0022-2u0022 clean rock to keep flow paths open. Due to regional sourcing, color and texture may vary across West Montana.

Use the rule cubic yards = area(sq ft) x depth(in) / 324, and assume 1 cubic yard ≈ 1.4 tons. Example estimates for a 3u0022 finished layer: 1-car (12x20) ≈ 2.2 yd3 ≈ 3.1 tons; 2-car (20x20) ≈ 3.7 yd3 ≈ 5.2 tons; 3-car (30x20) ≈ 5.6 yd3 ≈ 7.8 tons. A 12x12 patio at 2u0022 depth ≈ 0.9 yd3 ≈ 1.3 tons, and a 100 ft long swale 2 ft wide at 6u0022 deep ≈ 3.7 yd3 ≈ 5.2 tons; for driveways you may want a 4u0022–6u0022 compacted base, which would increase quantities proportionally.

Hello Gravel works with trusted local suppliers and contracted dump truck fleets in the Helena area to handle delivery and scheduling. Minimum order through Hello Gravel is 3 tons; typical tri-axle dump trucks used for delivery carry roughly 12–18 cubic yards (about 10–16 tons) depending on local weight limits and material density. Some local suppliers and haulers offer tailgate spreading or spreading and compaction for an additional fee, but spreading is at the driver or contractor’s discretion and should be requested at checkout or when you get your delivery confirmation.

Freeze-thaw cycles and snow plow traffic in Helena can move rounded rock and cause rutting or washouts, so angular crushed rock that locks together performs best for driveways. Expect to regrade and replenish a driveway or path once every 1–3 years depending on traffic, and after spring thaw inspect for washouts and re-level; swales may need clearing after heavy rains. Use edging, geotextile underlayment on poor soils, and periodic top-up of 1u0022 of material as simple maintenance steps to extend performance.

Driveway permits, curb cut rules, and stormwater requirements can apply inside Helena city limits or for Lewis and Clark County properties, especially if you alter a city curb or connect to a public road. Before you install, contact City of Helena Public Works or Lewis and Clark County Road and Bridge to confirm setback, apron, and drainage requirements and whether an access permit is needed. Local code officials will provide the specific rules and any inspection steps required.

Yes. The Montana Department of Transportation (MDT) sets standards for state highways, and county road departments set specs for local and rural roads; access permits, shoulder design, and drainage structures can limit what materials and profiles are allowed for public connections. For projects near state or county routes contact MDT or Lewis and Clark County before hauling or placing material to ensure your driveway or access meets local standards.

Labor and equipment costs vary with scope, but a compacted gravel driveway installation in Helena often runs roughly $800–$1,500 for a small 1-car drive and $1,500–$4,000 for a typical 2-car drive, depending on excavation, thickness, and finish. Cost components include grading and site prep, a compacted base layer (6u0022 is common for high-traffic drives), delivery of material, and compaction; equipment/operator rates often run in the $75–$150 per hour range. Get local quotes that itemize grading, base material, top course, and compaction so you can compare bids.

For small projects you can order the 3-ton minimum and use leftovers for garden beds, walkways, or future touch-ups, or buy bagged gravel from local home centers for very small amounts. Another option is to split a delivery with a neighbor or ask customer service about nearby suppliers that may offer smaller loads, but plan ahead since Hello Gravel’s minimum is 3 tons and changes are easier before an order is dispatched.
