Gravel in Seattle, WA

A typical tri-axle dump truck in the Seattle area carries about 10 to 12 cubic yards of gravel, which converts to roughly 12 to 18 tons depending on the rock type. Local road weight limits and material density (basalt is heavier than pumice) affect the exact tonnage, so your supplier will confirm the load size when you order.

Buying in bulk and ordering direct delivery is usually the cheapest option in Seattle. Use local suppliers to avoid long hauls, order at least the minimum (Hello Gravel's minimum is 3 tons), and compare material types like crushed recycled concrete which can be less expensive than quarried stone.

Prices vary by material and season, but crushed gravel in the Seattle area typically ranges from about $40 to $80 per ton for common driveway material, not including delivery or spreading. Exact pricing depends on particle size, whether it includes fines, and delivery fees; use Hello Gravel to get an upfront quote for your zip code.

Crushed hard rock such as basalt or crushed rock with angular particles and a mix of fines tends to be most durable in Seattle's wet climate because it compacts well and resists washout. For high-traffic driveways, consider a compacted base rock layer (3/4u0022 minus or road base) topped with a smaller crushed stone for a stable surface.

Costs depend on length, depth, and preparation, but a typical 20 ft by 20 ft driveway (400 sq ft) at a 3u0022 depth will need about 5 to 6 cubic yards (around 7 to 8 tons) of material. Material plus delivery in Seattle often runs $300 to $800, while professional grading and installation can push total costs to about $800 to $2,000.

No, 2 inches is generally only suitable for temporary paths or decorative top dressing. For a permanent driveway in Seattle's rainy conditions you should plan on 3 to 4 inches of compacted gravel over a properly prepared base, and 4 to 6 inches if you expect heavy vehicles.

Cost depends on width and prep, but a common estimate is $1.50 to $4.00 per square foot installed. For a 100 ft long by 10 ft wide driveway (1,000 sq ft), expect roughly $1,500 to $4,000 total installed, with lower numbers for material-only purchases and higher numbers including grading, base rock, and compaction.

Coverage varies with gravel density and desired depth, but 1 ton of typical crushed stone will cover about 100 to 120 square feet at a 2u0022 depth. If you need a deeper layer, like 3u0022 or 4u0022, the coverage per ton drops proportionally.

Recycled crushed concrete or crushed asphalt are often cheaper and locally available alternatives that perform well for driveways and paths. Keep in mind the look differs from natural stone and local availability and price swings with demolition and recycling markets.

Tonnage depends on width and depth. For a 100 ft long by 10 ft wide driveway at a 3u0022 compacted depth (1,000 sq ft), you would need roughly 9 to 13 tons of gravel; narrower drives or shallower depths require less, while wider or heavier-use drives need more.

Yes, many homeowners install gravel themselves; basic steps are clearing vegetation, grading, installing edge restraints, laying geotextile fabric if desired, adding a compacted base rock, and finishing with top gravel. Expect to rent equipment for compaction and plan for extra work because Seattle's slopes and wet weather make good prep important for long-term performance.

A well-installed gravel driveway or landscaped hardscape can improve curb appeal and address drainage issues, which may help resale value modestly. It is rarely a major value driver on its own, but it is cost-effective for improving appearance and function compared with some paving options.

You can, but it's not recommended without preparation because Seattle's wet soils and freeze-thaw cycles lead to rutting and washout. For lasting results, remove top vegetation, grade for drainage, add a compacted base layer and geotextile fabric, then place and compact the top gravel.

Products like resin-bound gravel, resin-stabilized aggregate, or polymeric stabilized mixes bind stones together and create a firm, semi-rigid surface. These systems are more expensive than loose gravel and usually require professional installation, but they reduce tracking and washout and work well in damp climates like Seattle's.

With proper base preparation and maintenance, a gravel surface can function for 5 to 20 years; high-traffic areas in Seattle often need topping up every 3 to 7 years. Wet weather, poor drainage, and vehicle use shorten intervals between refreshes, so annual raking and occasional replacement of fines will extend life.
