Fill Dirt in South Fork, CO

Expect variation, but in West Colorado delivered fill-dirt commonly runs in the approximate range of $20 to $50 per ton, depending on haul distance, access, and moisture. Using a rule-of-thumb density of about 1.4 tons per cubic yard, that is roughly $28 to $70 per cubic yard.

Calculate volume (square feet x depth in feet) to find cubic feet, then divide by 27 to get cubic yards. As an example, a typical 2-car driveway 20' x 24' at 6u0022 deep is about 9 cubic yards (order ~10–11 cy allowing for compaction), which is roughly 14–16 tons using 1.4 t/yd. Small yard grading needs vary; for 1,000 sq ft at 2u0022 depth you would need about 6 cubic yards (roughly 8–9 tons). Always order 5–15% extra to cover compaction and settling.

For South Fork's high-elevation freeze-thaw cycles, choose a well-graded granular fill with mostly sand, gravel, and minimal clay or organic matter so water can drain and not hold frost. For areas that need frost protection or structural support, a clean crushed-rock layer (for example 3/4u0022 minus or 3/4u0022 crushed with limited fines) below surface fills improves drainage and reduces heaving. Avoid using topsoil or high-clay native dirt as structural fill; if in doubt, ask for a supplier mix suited to frost-prone mountain climates.

Hello Gravel partners with local suppliers and haulers serving South Fork and nearby towns (Del Norte, Monte Vista, Alamosa) and will show available options when you enter your zip code. Our nationwide minimum order is 3 tons, but in remote or high-elevation runs minimums or delivery fees may be higher because of long hauls or truck routing — the checkout quote will show any differences. If you need less than the minimum, consider pickup from a nearby supplier or combining orders with neighbors or a contractor.

Fill-dirt is typically used for rough grading, raising low spots, foundation backfill, utility trenches, and under engineered gravel bases for driveways. Typical recommended compacted depths: driveway subfill/grade adjustments 4–8 inches beneath a proper base, foundation backfill 6–12 inches in lifts with compaction as required, and landscaping rough grading 2–6 inches before finishing with topsoil or mulch. For septic systems, building pads, or engineered work follow plans and local code requirements and verify depth and compaction with your engineer or county.

Permitting and compaction requirements vary by project type and location; building sites, driveways tied to public right-of-way, and septic systems often have county-level rules in Rio Grande County. Structural fills commonly require staged placement and compaction to specified densities (engineers often call for 90–95% of modified Proctor), and inspections may be required. Contact Rio Grande County Building and Planning or your project engineer before large fills to confirm permits and compaction testing needs.

High elevation, steep grades, narrow mountain roads, or switchbacks can increase delivery costs because trucks may need different routes, smaller rigs, or extra time and equipment. Access restrictions also affect the type of material you should choose — heavier, well-draining granular fills are often preferred on slopes to reduce frost heave and settling, while fine, wet soils are harder to place and compact on steep sites. When ordering, provide clear access notes and photos so suppliers can assign the right truck and estimate any extra charges.

Fill-dirt is primarily fine material used for grading and backfill; it is not a durable wearing surface on its own. Roadbase and crusher-run are angular, well-graded mixes with enough fines to compact into a rigid base and are the preferred structural layer for driveways, while crusher-fines (very small particles) make a smoother finished surface for paths or low-traffic driveways. For South Fork driveways, use a compacted roadbase layer (6–8 inches) with crusher-fines or a wearing course on top rather than relying on fill-dirt as the driving surface.

A properly engineered and compacted base (roadbase/compacted fill with good drainage) can last many years, but pure fill-dirt used as a surface will rut, erode, and need frequent regrading, especially with freeze-thaw and snowmelt. Expect annual or seasonal spot repairs, regrading, and attention to drainage for any surface in mountain climates; adding a durable wearing layer and maintaining culverts and swales reduces long-term maintenance. Regular inspections after spring thaw help catch issues early.

Fill-dirt density varies with moisture and composition, but a practical rule-of-thumb for crushed/fill-dirt mixes is 1.3 to 1.6 tons per cubic yard; many suppliers use 1.4 tons/cubic yard as a working average. To convert: tons = cubic yards x 1.4 (example: 10 cy x 1.4 = 14 tons). Always confirm the supplier's density assumption on your quote and add 5–15% for compaction and waste when placing the order.
