Premium Aggregates Available for Greenbrae Delivery
Marin County residents have access to our complete inventory of crushed stone, gravel, and specialty materials. Each product is carefully selected to meet the specific demands of Northern California properties, from coastal influences to hillside terrain.
Crushed Stone Products
Crushed stone forms the foundation of most aggregate projects in Greenbrae. Our 3/4 inch crushed stone is the most versatile option for Marin County homeowners. This angular aggregate compacts well and provides excellent stability for driveways, pathways, and foundation applications. Properties along Sir Francis Drake Boulevard and throughout the Kentfield area frequently use this material for its drainage capabilities.
For projects requiring superior interlocking properties, our #57 stone delivers exceptional performance. This uniformly-sized aggregate is perfect for drainage systems and base layers, making it ideal for properties on the hillsides above Greenbrae where water management is critical during the rainy season.
The Ross Valley receives approximately 35-40 inches of rainfall annually, concentrated between November and April. This Mediterranean climate pattern means proper drainage is essential for protecting foundations and preventing erosion. Our drain rock is specifically designed for French drains and foundation drainage systems throughout Greenbrae and Larkspur.
- 3/4 Inch Crushed Stone - Excellent compaction for driveways and base applications
- #57 Stone - Uniform sizing for drainage and decorative installations
- Drain Rock - Essential for managing Marin County's winter rainfall
- Crusher Run - Perfect blend of stone and fines for maximum stability
Driveway and Pathway Materials
Greenbrae properties range from flat lots near the Bon Air Shopping Center to steep hillside homes with dramatic Bay views. Each terrain type requires specific aggregate solutions. Our driveway gravel provides the durability needed for Marin County weather conditions while maintaining an attractive appearance year-round.
For pathways and patios throughout Greenbrae, walkway gravel offers a comfortable surface that drains quickly and complements the natural beauty of the area. Many residents near Corte Madera Creek and the walking trails along the bay choose this material for its balance of functionality and aesthetics.
Our crusher run material combines crushed stone with stone dust to create a stable, compacting surface. This blend is particularly effective for Greenbrae properties with sloped driveways, as it resists migration and maintains its structure even during heavy winter storms.
Decorative Stone and Gravel
The Mediterranean climate of Marin County makes decorative aggregates an excellent choice for water-wise landscaping. Pea gravel provides a smooth, rounded surface perfect for garden paths, seating areas, and succulent gardens. Its natural earth tones blend beautifully with the golden hillsides and oak woodlands that characterize the Greenbrae landscape.
River rock in various sizes creates stunning focal points in Marin County gardens. Whether used in dry creek beds, water features, or as ground cover, these naturally tumbled stones reflect the waterways that define our region, from Corte Madera Creek to Richardson Bay.
Decomposed granite has become increasingly popular throughout Greenbrae and the greater Ross Valley. This natural material packs firm when wetted and compacted, creating stable pathways that complement drought-tolerant native plantings. Properties in Kentfield and San Anselmo frequently incorporate decomposed granite into their outdoor living spaces.

Soil and Fill Materials for Greenbrae Properties
Beyond aggregates, successful projects in Marin County often require quality soil products. The clay-heavy soils native to many Greenbrae hillsides can present challenges for gardening and construction alike. Our soil products help address these local conditions.
Topsoil for Gardens and Lawns
Greenbrae gardeners know that good soil makes all the difference. Our topsoil is screened and blended to provide optimal growing conditions for the vegetables, flowers, and native plants that thrive in Marin County's climate. Whether you are establishing raised beds near your Kentfield home or amending existing garden areas in Larkspur, quality topsoil creates the foundation for successful planting.
The growing season in Greenbrae extends nearly year-round thanks to mild temperatures. Average highs range from the mid-50s in winter to the upper 70s in summer, with rare frost events. This extended season means your topsoil investment pays dividends throughout the year.
Fill Dirt for Grading and Construction
Many Greenbrae properties, particularly those on the hills overlooking the bay, require grading and leveling work. Our fill dirt provides clean, compactable material for raising grades, filling holes, and creating level building pads. Properties near Corte Madera Ridge and throughout the hillside neighborhoods often need fill dirt for retaining wall backfill and slope stabilization projects.
Road Base for Heavy-Duty Applications
Commercial properties and larger residential driveways in Greenbrae benefit from our road base material. This carefully graded aggregate creates a stable sub-base that distributes weight evenly and prevents settling. Properties along busy Sir Francis Drake Boulevard and the commercial areas near Bon Air frequently specify road base for maximum durability.
Recycled Concrete Options
Environmental consciousness runs deep in Marin County, and many Greenbrae residents prefer sustainable material options. Our crushed concrete provides an eco-friendly alternative to virgin aggregates for driveways, pathways, and base applications. This recycled material performs comparably to new crushed stone while reducing construction waste in our community.
Specialty Sand Products Available in Greenbrae
From construction projects to recreational installations, sand plays an important role in many Marin County applications. We offer several sand varieties to meet the diverse needs of Greenbrae homeowners and contractors.
Mason sand provides the fine, consistent texture needed for mortar mixing, paver installations, and pool surrounds. Properties throughout Greenbrae use mason sand for setting flagstone patios and leveling paver installations in outdoor living areas.
Families in Greenbrae appreciate our playground sand for backyard play areas and sandboxes. This clean, screened sand meets safety standards while providing hours of outdoor entertainment for children. The mild Marin County climate makes outdoor play areas usable nearly year-round.
For construction and utility applications, our washed sand delivers clean material free from clay and organic matter. This sand works well for pipe bedding, concrete mixing, and erosion control projects throughout the Ross Valley.
- Mason Sand - Fine texture for mortar and leveling applications
- Playground Sand - Clean, safe sand for children's play areas
- Washed Sand - Versatile option for construction and utility work

Understanding Marin County Geology and Climate
Successful aggregate selection in Greenbrae requires understanding local conditions. The geology of Marin County features a complex mix of Franciscan Formation rocks, including serpentine, chert, and sandstone. These parent materials contribute to the clay-rich soils that predominate in many areas, making drainage a critical consideration for most projects.
Rainfall and Drainage Considerations
The Mediterranean climate brings distinct wet and dry seasons to Greenbrae. Most rainfall occurs between November and April, with individual storms sometimes delivering several inches in a single event. Properties on hillsides must manage water flow to prevent erosion and protect foundations. Our drain rock and crushed stone products provide the permeability needed to handle these seasonal deluges.
During summer months, fog from the Pacific moderates temperatures and provides moisture to coastal-facing slopes. This pattern supports the region's famous redwood groves and oak woodlands while also reducing irrigation needs for properly designed landscapes featuring decomposed granite and pea gravel.
Seismic and Slope Stability
Like all Bay Area communities, Greenbrae sits in an active seismic zone. Proper aggregate compaction and drainage help protect foundations and retaining walls from earthquake damage. Our crusher run and road base materials provide the stable base layers essential for construction in seismically active regions. Many Greenbrae contractors specify our materials for projects requiring maximum stability and compaction.

We deliver a comprehensive selection of aggregates including crushed stone in multiple sizes, driveway gravel, pea gravel, river rock, decomposed granite, drain rock, crusher run, road base, crushed concrete, topsoil, fill dirt, and various sand products.

For rectangular areas, multiply length times width times depth in feet, then divide by 27 to get cubic yards. For example, a 20 by 10 foot driveway with 4 inches of gravel needs approximately 2.5 cubic yards. Our team can help you calculate quantities for irregular shapes or complex projects. We recommend adding 10 percent extra to account for compaction and settling.
For hillside driveways common in Greenbrae, crusher run provides excellent stability because the mixed particle sizes interlock and resist migration. For drainage applications on slopes, 3/4 inch crushed stone or drain rock allows water to flow freely while remaining in place. Decomposed granite works well for pathways on moderate slopes when properly compacted.
Most orders to Greenbrae and surrounding communities can be delivered within a few business days, depending on current demand and weather conditions.
