Fill-dirt in Redmond, WA

Fill-dirt is clean, typically low-organic soil used to raise or level grades, fill trenches, and backfill around foundations. In Redmond it’s commonly used to correct slopes, raise yard elevations after utility work, or create a base before installing lawn or hardscape. It is not topsoil, so you’ll usually cap it with topsoil or gravel before planting or finished surfacing.

Prices vary by supplier, haul distance, and site access, but expect roughly $20 to $45 per cubic yard delivered, or about $15 to $35 per ton as a ballpark. Costs trend higher in the Seattle/Redmond area due to transportation and local demand; ask for a delivered quote that includes placement and any small-access fees.

Homeowners use fill-dirt for yard leveling, raising low spots, backfilling footings, creating gentle grades around foundations, and prepping subgrades before laying patios or artificial turf. Contractors may also use it for site grading, utility backfill, and preparing areas before installing gravel driveways or retaining walls (with proper drainage materials).

Redmond’s wet winters and clay-prone soils can hold water and reduce drainage if you use fine, clay-rich fill alone. For stable performance, contractors often combine fill-dirt with coarse granular layers, add drainage (perforated pipe, gravel), and compact in thin lifts to avoid long-term settling and saturated spots. Plan work for drier months when possible and include erosion control during rainy periods.

For driveway subbase, local pros generally use a compactable granular road base or crushed rock (often 3/4u0022 minus or crusher fines) rather than plain fill-dirt, because it drains and compacts reliably under traffic. For general landscaping and grade build-up, contractors use clean fill-dirt or engineered fill with low organic content, then cap with topsoil for planting. For retaining wall backfill, use free-draining material like washed gravel or crushed rock instead of fine fill-dirt to avoid hydrostatic pressure.

You may. Large grading, import of substantial fill, work near critical areas, septic systems, or changes to drainage often trigger permits or plan review from the City of Redmond Development Services. Always check with the City of Redmond (and King County if applicable) before hauling large volumes; they can advise permit thresholds, erosion-control requirements, and inspection rules.

Most suppliers serving Redmond use tri-axle dump trucks and require a minimum order (Hello Gravel minimum is 3 tons). Standard delivery is usually 2+ business days, with next-day options available for orders placed early and often subject to an extra fee. Drivers will place material where safe and accessible, but tight driveways or steep approaches may limit placement and could incur additional fees.

Measure the area and depth to calculate cubic yards (length x width x depth in feet ÷ 27). A rule of thumb is one cubic yard of loose fill-dirt weighs about 1.2 tons; compacted fill can weigh 1.4 to 1.6 tons per cubic yard, so ask your supplier for an estimate in both cubic yards and tons. Use Hello Gravel’s material calculator or contact our team with your measurements for a quick quote.

Protect lawns and driveways by laying plywood or mulch at truck approach points and identify the preferred dump location before arrival to limit landscaping damage. Schedule deliveries for drier windows when possible, request the driver’s placement plan at checkout, compact the material in thin lifts for structural areas, and keep erosion controls in place during winter rains to prevent runoff.
