Fill Dirt in St. Maries, ID

Fill-dirt is natural soil (usually low in organic material) used to raise grade, fill depressions, and backfill around foundations. In St. Maries it is commonly used to level yards, build up subgrades for pads and garages, and correct drainage low spots before adding a gravel or paved surface. Because materials are regionally sourced, you may see local silty or alluvial textures reflective of West Idaho geology.

Delivery cost depends on distance, load size, and access; typical local truck delivery in the St. Maries area often ranges from about $100 to $400 per load, with smaller residential deliveries toward the higher end per ton. Contractors ordering full truckloads get lower per-ton hauling costs, while homeowners ordering just above the 3-ton minimum will see a higher per-ton price.

Hello Gravel requires a 3-ton minimum order, and many local suppliers can meet that or supply a full truckload. Typical dump truck loads in the region are roughly 10 to 14 cubic yards (varies by truck), so contractors often order full trucks for best pricing. Regional sourcing means some suppliers may have limited stock seasonally, so check availability when you schedule delivery.

Use this quick formula: cubic yards = (square feet x depth in feet) / 27, and then multiply cubic yards by about 1.2 to estimate tons (local moisture/compaction can change this). Example: to raise 1,000 sq ft by 4 inches (0.333 ft) you need about 12.3 cu yd, roughly 15 tons. For a 2-car garage pad 24 ft x 24 ft raised 6 inches you need about 10.7 cu yd, roughly 13 tons—always add 5-10% for settlement and compaction.

Fill-dirt is fine for raising grades and filling low spots, but it is not an ideal finished surface in a freeze-thaw climate or where clay soils dominate. In St. Maries you should use fill-dirt as subgrade material, then cap with well-draining layers (crushed rock or road base) to reduce frost heave and improve drainage. Avoid using uncompacted fill-dirt as a driving or walking surface without a proper structural base.

Compact fill in uniform lifts—6 to 8 inches loose depth is common—using a plate compactor for small areas and a vibratory roller for larger sites. Control moisture: slightly damp material compacts best, while overly wet or frozen soil won’t compact well. For projects over a few yards or where structural support is required, hire a contractor with compaction equipment and test results if needed.

Small landscaping fills commonly do not require a permit, but changes that affect drainage, grading, retaining walls, or building pads often do. Check with the City of St. Maries Building and Planning departments and Benewah County before larger grading projects to confirm permit and setback requirements. When in doubt, contact local authorities or ask our team and we can point you to the right office.

Fill-dirt is less expensive and good for bringing grade up or filling, but it does not provide the drainage or structural strength of crushed rock or road base. For St. Maries driveways exposed to freeze-thaw and wet soils, we recommend using fill-dirt only as subgrade and placing a layer of compacted road base or crushed rock on top for durability. That combination gives better load-bearing performance and reduces maintenance over time.

Expect initial settlement over the first year, especially after winter freeze-thaw and heavy rains; plan on spot regrading or adding material as needed during the first 6–12 months. If you cap fill-dirt with a structural gravel or paved surface and keep drainage controlled, the system can remain stable for many years. Uncapped fill-dirt used as a finished surface will need more frequent maintenance and regrading.

For structural fills, a well-graded material with a mix of fines and coarse particles compacts better—contractors often specify '3/4 inch minus' or engineered fill depending on the job. If drainage is a priority, put a coarse, free-draining layer (gravel or crushed rock) above the fill-dirt and consider geotextile separation from soft native soils. Ask your supplier for a gradation or material description so you can match the material to the project.

Costs vary by access, project size, and equipment needed, but small residential jobs (site prep, delivery, compaction for a garage pad or yard raise) often fall in the $500 to $1,500 range. Larger site-prep projects requiring excavators, rollers, and trucking can run several thousand dollars; contractors usually price by the hour plus materials and haul. For accurate pricing, get written estimates that list labor, equipment, compaction, and haul separately.

Order online by selecting fill-dirt, entering your address, and choosing a delivery date; our platform connects you with local suppliers and shows pricing based on your zip code. Minimum order is 3 tons; standard delivery takes 2+ business days and next-day delivery is available if ordered before noon CST for an extra fee. You can request tailgate spreading at checkout, but drivers perform spreading at their discretion, and we recommend adding delivery notes for access and drop location.
