Fill-dirt in Superior, CO

Prices vary by supplier, truck mileage, and material quality, but expect a rough range of $15 to $40 per ton (about $12 to $30 per cubic yard) for common fill-dirt delivered to Superior, Colorado. Moisture content, required screening, and haul distance from local pits in West Colorado can push prices to either end of that range.

Hello Gravel requires a 3-ton minimum order; most local suppliers working with our platform commonly deliver by tri-axle dump truck. Standard delivery is 2+ business days, and next-day delivery may be available for orders placed before noon CST for an extra fee, but exact lead times depend on supplier schedules and local hauling availability.

For non-structural yard fill use clean, low-organic fill-dirt that is free of large roots and debris and that compacts well. For driveway base, use fill-dirt only as a bulk lift to raise grade; finish the structural base with a well-graded road base or crushed stone (typically a compactable mix with angular particles). If you need engineered fill for retaining walls or structural support, ask for supplier gradation certificates or a soils engineer recommendation specific to Boulder County conditions.

Superior's freeze–thaw cycles and pockets of clay can increase the risk of frost heave and long-term settlement if material and compaction are not managed. Use non-frost-susceptible, well-draining fill and compact in 6u0022 or smaller lifts to achieve stable density; also provide surface and sub-surface drainage to keep water away from fill zones. For critical elevations or near foundations, consult a soils engineer to specify material and compaction requirements.

Loose-to-compacted ratios for common fill-dirt usually range from 1.2:1 to 1.4:1 (loose depth 20% to 40% greater than final compacted depth), depending on soil type and moisture. For small residential areas, a 4,000–8,000 lb plate compactor or walk-behind vibratory plate is common; larger projects often use a tandem vibratory roller or sheepsfoot roller to reach required densities. Aim for staged compaction in 4–8u0022 lifts for best results.

Permit requirements vary by project and location; small landscape fills are often allowed without a building permit, but larger grading, regrading of lots, or filling that affects drainage may require permits from the Town of Superior or Boulder County. Always check with the Town of Superior planning or Boulder County land-use office before importing large volumes, and if in doubt call local permitting to confirm thresholds and erosion-control requirements.

Use these local estimates: 1 cubic yard = about 1.2 tons of fill-dirt (approximate; varies with moisture and material). Example calculations: a 1-car driveway area 10' x 20' with 12u0022 (1 ft) of fill = 200 cu ft = 7.4 cu yd ≈ 9 tons; raising 500 sq ft by 6u0022 = 500 x 0.5 ft = 250 cu ft = 9.3 cu yd ≈ 11 tons. Always order 5-10% extra for compaction and minor grading adjustments, and ask Hello Gravel for a calculator-based estimate for your exact zip code.

Fill-dirt is mainly used to raise elevation or fill voids and should be low in organics; it is not a durable wearing surface. Road base or crushed stone provides structural strength and drainage for driveways and is recommended as the top structural layers. Crusher fines are compactable and good for paths or secondary driveway surfaces, while topsoil is for planting and is not suitable as structural fill; costs and drainage performance follow this hierarchy: topsoil (cheapest for planting) u003c fill-dirt (inexpensive bulk) u003c crusher fines/road base (higher cost but necessary for durable driveways).

Use erosion-control blankets, hydroseed or native grass restoration, and silt fences for newly placed fills on slopes common around Superior. Install woven or nonwoven geotextile fabrics on steep slopes or at interfaces between poor subgrade and fill to separate materials and reduce migration. For slopes over 3:1 or fills near waterways, follow Boulder County erosion-control guidance and consider terracing or retaining walls with proper drainage.

Frequent issues include settlement after initial placement, poor drainage caused by clay-rich fills, and deliveries placed in the wrong spot. To avoid problems, specify low-organic, well-draining fill, compact in lifts, provide positive drainage away from structures, and add clear delivery notes to your Hello Gravel order with the desired drop location and any access constraints. If issues arise, contact Hello Gravel customer support promptly so we can coordinate with the local supplier.
