Hello Gravel requires a minimum order of 3 tons. Our haulers typically use dump trucks ranging from single-axle (6-8 tons) to tandem-axle (10-14 tons) and tri-axle trucks (around 18-22 tons); tri-axles are most common for residential deliveries. If you need a specific placement or have tight access, mention it at checkout so the driver and supplier can plan accordingly.

Raise 1,000 sq ft by 6 inches equals 500 cubic feet, which is about 18.5 cubic yards. Fill-dirt generally weighs about 1.2 to 1.4 tons per cubic yard, so you would need roughly 22 to 26 tons. We recommend ordering a small extra allowance (5-10%) to account for settling and compaction; use our material calculator for an exact quote.

Fill-dirt is not a good surface for driveways in Post Falls' freeze-thaw climate because it holds water and can rut or settle. Crushed rock or gravel with a compacted base is recommended for driveway surfaces; fill-dirt can be used beneath as a grade-raising or backfill material if properly compacted and drained. For driveways, plan on a compacted granular base and a wear layer of crushed rock to resist freeze-thaw damage.

For small areas, use a plate compactor or jumping jack; for larger areas, a vibratory roller or sheepsfoot roller is typical to reach needed density. Many contractors in Kootenai County and the greater West Idaho area offer compaction services, especially for construction or driveway prep. Hello Gravel can request that drivers perform tailgate spreading at their discretion, but professional compaction should be arranged directly with a local contractor.

Standard fill-dirt often retains moisture and can worsen drainage issues in clay-rich soils common around Post Falls. For areas next to foundations, use free-draining material (clean granular fill or crushed rock) to direct water away from structures and slope the grade at least 2% away from the foundation. If clay is present, consider installing drainage solutions like French drains and consult a local contractor or engineer for critical foundation work.

Significant grading, changes to drainage, or large fill projects often require permits or reviews from the City of Post Falls or Kootenai County. Permitting thresholds vary by project size and location, so check with the Post Falls Planning and Building Department before importing large volumes. If your project affects wetlands, riverbanks, or public right-of-way, you will likely need additional approvals.

Yes, availability and pricing can change seasonally in northern Idaho. Winter conditions, frozen ground, or limited hauling windows can increase costs or restrict delivery dates, and some suppliers may charge extra for winter service. We recommend scheduling deliveries in advance and asking about seasonal surcharges when you request a quote.

Fill-dirt used as subgrade will settle over time; with proper compaction it can be long-lasting under a well-designed driveway, but it is not a wearing surface. Expect to top and regrade surfaces of driveways every few years depending on use and drainage; the granular wearing layer will need most of the maintenance. For best longevity in Post Falls' climate, ensure good drainage, a compacted subbase, and a stable gravel wearing course.

Fill-dirt by itself is a poor long-term erosion-control solution on slopes or riverfronts because loose soil can wash away during heavy rain or spring runoff. Use engineered measures such as vegetation, erosion-control blankets, terraces, riprap, or retaining structures along with proper drainage to stabilize slopes. For riverfront work, coordinate with local agencies since permits and professional design are often required.

Measure the area and use our calculator to estimate yards or tons, and order 5-10% extra for settling. Mark the delivery spot, clear overhead lines and obstacles, and note any access restrictions in Order Notes so drivers can plan. Request delivery dates early—standard delivery is 2+ business days and next-day is available for orders placed before noon CST—then confirm placement expectations with your driver on arrival.

Drivers may be able to perform tailgate spreading at their discretion; request it at checkout but understand there is no guaranteed spreading service. Hello Gravel coordinates delivery logistics but does not provide guaranteed compaction; for reliable compaction, we recommend hiring a local contractor. Contact our sales team if you want help finding local spreading or compaction contractors in the Post Falls area.
