Fill Dirt delivery in Kennewick, WA

Fill-dirt is used to raise grade but is not a good final structural base for a patio. For pavers or a concrete slab you should place and compact a crushed rock or gravel base on top of any fill-dirt to ensure drainage and stability. In Kennewick's dry climate, compacting layers and adding a proper base helps prevent settling and uneven surfaces.

Add 4 to 6 inches of quality topsoil or a topsoil-compost mix over your fill-dirt for lawns and planting beds. In the Tri-Cities area, amend silty or sandy fill with organic matter and water lightly to help new plantings establish. If you expect heavy settling, wait a few weeks or regrade after initial settlement before seeding or sodding.

Use this formula: cubic yards = (square feet x depth in inches) / 324. For a 10x10 area (100 sq ft) at 3 inches deep you need about 0.93 cubic yards, which is roughly 1.1 to 1.4 tons depending on moisture and compaction. Always order 10-15% extra to allow for settling and compaction, and remember Hello Gravel's minimum order is 3 tons.

A compacted gravel surface is generally cheaper upfront than a concrete slab. If you need to bring the site up with fill-dirt first, that adds hauling and material cost in Kennewick, which narrows the price gap. Choose a slab when you need a durable, low-maintenance surface; choose gravel when budget and drainage are priorities.

Compact fill-dirt in 4 to 8-inch lifts with a plate compactor or roller until it reaches the desired firmness. In many Kennewick projects a geotextile fabric under the fill, proper drainage, and a compacted crushed rock cap will prevent future settling. Moisture conditioning while compacting helps achieve consistent density.

A ton of fill-dirt is roughly 0.8 to 0.9 cubic yards depending on moisture and material. That equates to about 260 sq ft at 1 inch deep, 130 sq ft at 2 inches, or about 43 sq ft at 6 inches. Use the cubic yard formula ((sq ft x depth in inches) / 324) and then convert yards to tons for your exact estimate.

Yes, you can cap fill-dirt with crushed gravel, but preparation is key: compact the fill in layers, install geotextile if needed, and place a 4 to 6 inch compacted crushed-rock base for a residential driveway. Kennewick's semi-arid climate reduces frost issues, but good drainage and compaction are still essential for longevity. For heavier traffic or vehicles, consider a thicker base or a paved surface.

No, fill-dirt reflects local geology so color, texture, and rock content will vary across the Tri-Cities area. Expect natural variation and note any special requests in Order Notes at checkout. If appearance or fines content matters for a visible area, ask customer service for a description of the local supplier's material before ordering.

If you properly place and compact the fill-dirt in lifts, you can build on compacted areas soon after delivery; for plantings, it is best to add and prepare a topsoil layer first. If fill was not mechanically compacted, allow time for natural settlement and regrade after a few weeks; moisture cycles in Kennewick can accelerate settling in loose fills. For critical structures, consult an engineer or contractor for compaction requirements.

Hello Gravel has a 3-ton minimum order, so for very small jobs consider sharing an order with a neighbor, landscaping crew, or buying bagged material from a local nursery. You can also order 3 tons and ask the driver about offload location or spreading options, but remember tailgate spreading is at the driver's discretion. Contact our sales team to discuss small-job options and delivery timing for the Tri-Cities.
