Aggregate & Gravel Supply in Snohomish County, Washington

Crushed Stone, Driveway & Base Aggregates

For long-lasting driveways and structural bases, choose the right crushed stone and base mixes. We recommend specific aggregates depending on slope, subgrade, and expected traffic.

Common driveway builds

• Subgrade preparation with compacted fill dirt and geotextile
• Base layer of road base or crusher run for strength
• Top wearing course of 3/4 inch crushed stone or driveway gravel

Recommended materials for driveways

Start with a compactable base and finish with a wearing course engineered for Snohomish County conditions.

• Road Base provides structural support for heavy loads
• Crusher Run locks together when compacted
• 3/4 inch Crushed Stone or Driveway Gravel for a durable surface

Sands, Soils, and Fine Materials

Snohomish County projects often require specific sands and soils to handle drainage and plant health. Our screened topsoil and variety of sands suit planting beds, masonry, and playgrounds.

Topsoil and fill

Topsoil is screened and blended for planting while Fill Dirt helps correct grade and fill low spots. For lawns and garden beds, improving drainage with suitable topsoil reduces waterlogging in heavy local clay pockets.

Sands for construction and play

• Mason Sand for mortar and precise leveling
• Playground Sand that meets safety expectations for schools and parks
• Washed Sand for proper drainage under pavers

Decorative Rock and Hardscape Aggregates

Decorative rock enhances curb appeal and can help direct water away from foundations. Our decorative aggregates are selected for color, texture, and performance.

Common decorative uses

• Mulch alternative around shrubs and trees
• Dry creek beds and rain gardens using river rock
• Pea gravel for patios and play areas

Choose from rounded and angular materials depending on style and function:

• River Rock - natural look, good for slow water flow areas
• Pea Gravel - comfortable underfoot, good for paths
• Decomposed Granite - compactable and low maintenance

Drainage, Erosion Control, and Site Prep

Snohomish County’s rainy season makes proper drainage a priority. Using the right aggregates reduces water damage and erosion on slopes and near foundations.

Materials for drainage

• Drain Rock - angular and free-draining for French drains
• #57 Stone - great for footing drains and concrete aggregate
• Crushed Concrete - recycled option for stable drainage layers

Erosion control strategies

Combine erosion control fabric with appropriate rock sizes on slopes and channels. Using heavier river rock near outlets and drain rock in trenches helps manage stormwater during heavy fall and winter rains.

Comparison of Popular Gravel Types

How Local Conditions Affect Aggregate Choice

Snohomish County sits between the Puget Sound and the Cascade foothills. The maritime climate brings wet winters and relatively dry summers. Many areas have glacially derived soils mixed with pockets of silty clay or sandy loam. This affects drainage and compaction behavior.

Soil and slope considerations

• Lowlands near the Snohomish River and estuaries often have silty, poorly drained soils; use drain rock and 57 stone for effective drainage.
• Hilly foothill properties near the Cascades can be rocky and require strong base materials like crusher run and road base.
• Urban lots in Everett and Lynnwood may need imported topsoil for planting and decomposed granite or walkway gravel for low-maintenance yards.

Climate and seasonal planning

Plan driveway and site work for late spring through early fall when ground is driest. For winter drainage projects, choose free-draining aggregates and consider slope stabilization during rainy months.
