Fill Dirt in Downey, ID

Typical delivered prices for fill-dirt in West Idaho and around Downey range roughly from $12 to $30 per ton, depending on haul distance, material quality, and seasonal demand. Remote or long-haul deliveries to rural Downey properties can be at the higher end of that range, and Hello Gravel will provide an exact quote for your zip code and requested amount.

Local suppliers are usually county gravel pits, landscape yards, and nearby suppliers around Jefferson County and the Idaho Falls area; exact vendors vary by ZIP code. Minimum order sizes commonly start at about 3 tons (Hello Gravel minimum) up to 5–10 tons for some local yards, and standard lead time is 2+ business days with next-day options available if ordered before noon CST; contact Hello Gravel to see specific suppliers, minimums, and exact lead times for your address.

Fill-dirt itself is typically fine-grained (silt, sand, clay) and is best for raising grades or non-structural fill. For driveways use a well-graded base such as crusher run or 3/4u0022 minus gravel under a wearing layer; for building pads and structural backfill use granular, compactable fill (clean sand/gravel or engineered fill) with limited organic material. If you plan structural work, ask a builder or engineer for a spec so the supplier can match the material.

Downey experiences seasonal freezing and thawing, which can cause frost heave in fine, wet, or organic-rich fill. To reduce problems use well-draining granular fill, compact in proper lifts, keep moisture controlled, and maintain surface drainage away from structures. For frost-susceptible locations, contractors often recommend a non-frost-susceptible aggregate layer beneath slabs and driveways.

Jefferson County and local building departments commonly require engineered fill, compaction to specified percentages, or compaction testing for foundations and slab-on-grade work. Requirements vary by project scope, so check with Jefferson County Building Department or your project engineer early; Hello Gravel can help supply materials that meet typical compaction and testing specs but cannot determine permit conditions.

Local contractors may use clean, non-organic fill-dirt for trench backfill around septic lines, but for garage slab bases they generally prefer granular, compactable material rather than organic-rich topsoil. Typical compaction practice is mechanical compaction in lifts (6–8 inches loose) to roughly 90–95% relative compaction (per a Proctor test) using plate compactors for small areas or vibratory rollers/sheepsfoot rollers for larger sites.

Fill-dirt is usually the least expensive option but may contain fines and organics that make it less durable and more prone to settling and frost heave. Crusher run offers a stronger, load-bearing base for driveways and slopes at a moderate cost, while engineered fill is the most expensive but is tested and placed to meet structural requirements. For long-lasting driveways and load-bearing areas in Downey, contractors typically prefer crusher run or engineered fill over plain fill-dirt.

Typical delivery trucks are single-axle dumps (about 8–10 cubic yards) and tri-axle dumps (about 12–16 cubic yards) with loose cubic yards converting to roughly 1.1–1.5 tons per cubic yard depending on moisture and soil type. Hello Gravel's standard delivery window is 2+ business days, with a next-day option for orders placed before noon CST; rural Downey deliveries may add a day depending on supplier location and road access.

Order about 5–10% extra to allow for settlement and grading waste, and make sure delivery access is clear of low branches and utility lines. Mark property lines and preferred dump location, request tailgate spreading in the checkout notes (driver will assess safety), and if your project is structural or near frost depth consult an engineer to specify material and compaction requirements before ordering.
