Crushed Stone and Gravel Products
Our crushed stone selection provides versatile options for construction and improvement projects throughout Korbel. 3/4 inch Crushed Stone remains one of our most popular choices for Humboldt County customers, offering excellent compaction and drainage characteristics that perform well in the wet climate. This angular stone locks together to create stable surfaces that resist erosion even during heavy winter rains.
For projects requiring specific stone sizing, our #57 Stone delivers consistent quality and performance. This mid-sized aggregate works exceptionally well for drainage applications around foundations and in French drain systems, which are common necessities for properties in the Korbel area where water management is a constant concern.
- Crushed Stone 3/4 inch - Ideal for driveway bases and foundation work
- #57 Stone - Perfect for drainage systems and decorative applications
- Angular aggregates - Superior interlocking for stable surfaces
- Washed stone options - Clean materials for visible installations
Driveway and Road Materials
The rural character of Korbel means many properties rely on gravel driveways and private roads. Our Driveway Gravel is specifically blended to withstand the heavy use and challenging weather conditions common to Humboldt County. Properties along Maple Creek Road, those accessed from Highway 299, and homesteads throughout the Mad River valley all benefit from properly installed driveway materials.
For more demanding applications, Road Base provides the structural integrity needed for private roads and heavily trafficked areas. This compacted aggregate blend creates a solid foundation that holds up under vehicle weight and resists the rutting that can occur during wet months. Many Korbel residents find road base essential for maintaining access to their properties year-round.
Our Crusher Run offers another excellent option for driveways and roads in the Korbel area. This material contains a blend of crushed stone and fine particles that compact together tightly, creating a smooth and durable surface. The natural binding action of crusher run makes it particularly effective in the damp conditions typical of Northern California.
Drainage Solutions for Humboldt County Properties
With Korbel receiving substantial rainfall throughout the year, proper drainage is not optional but essential. The region experiences its heaviest precipitation from October through April, and properties without adequate drainage systems often face erosion, flooding, and foundation damage. Our aggregates help Korbel homeowners protect their investments from water damage.
Drain Rock serves as the backbone of effective drainage systems throughout Humboldt County. This clean, angular aggregate allows water to flow freely while filtering sediment and preventing soil migration into drainage pipes. Whether you are installing a French drain near your foundation, creating a dry well, or improving drainage around a septic system, drain rock provides reliable performance.
The clay soils common around Korbel and the greater Blue Lake area retain water and expand when saturated. This soil movement can crack foundations and damage structures over time. Strategic placement of aggregates around your property helps direct water away from buildings and into appropriate drainage channels. Many local contractors recommend a combination of drain rock and crushed stone for comprehensive water management solutions.
Why Drainage Matters in the Mad River Valley
- Heavy annual rainfall - Over 60 inches per year requires effective water management
- Clay-rich soils - Natural soil conditions retain moisture and require drainage assistance
- Sloped terrain - Hillside properties need erosion control and directed water flow
- Seasonal flooding - Properties near the Mad River benefit from elevated surfaces and drainage
- Foundation protection - Proper aggregate placement prevents costly water damage
Walkways, Patios, and Decorative Aggregates
Creating beautiful outdoor spaces in Korbel requires materials that complement the natural surroundings while withstanding the local climate. Our selection of decorative aggregates helps homeowners design pathways, patios, and garden features that blend seamlessly with the redwood forest environment.
Walkway Gravel provides a perfect surface for paths connecting homes to gardens, outbuildings, and outdoor living spaces. The smooth texture and natural coloring work well with the forest aesthetic that defines properties in Korbel and surrounding communities like Fieldbrook and Glendale. This material drains quickly and maintains its appearance even during the wettest months.
For a more refined look, Pea Gravel offers smooth, rounded stones in natural earth tones. This aggregate is popular for patios, between stepping stones, and as a decorative mulch alternative in garden beds. The rounded profile makes pea gravel comfortable to walk on and safe for areas where children play.
Decomposed Granite creates elegant, natural-looking pathways that complement the rustic character of Humboldt County properties. This material compacts to form a firm surface while maintaining excellent drainage. Many Korbel residents choose decomposed granite for walkways that wind through their properties, as it blends beautifully with the native vegetation and redwood scenery.
River Rock adds visual interest to gardens, water features, and landscape beds throughout the Korbel area. Available in various sizes, river rock creates natural-looking borders, fills dry creek beds, and provides attractive ground cover. The smooth, water-worn appearance of river rock echoes the stones found naturally along the Mad River and its tributaries.

Soil and Earth Materials for Korbel Gardens
The gardening potential in Korbel is exceptional, with the mild maritime climate and abundant rainfall creating ideal growing conditions. However, the native soils often require amendment to reach their full potential. Our earth materials help local gardeners and landscapers improve soil quality and prepare sites for planting.
Topsoil provides the nutrient-rich growing medium needed for healthy plants, lawns, and gardens. Our screened topsoil is free of debris and ready for immediate use in raised beds, lawn establishment, and garden renovation projects. Many Korbel residents use topsoil to amend the heavy clay soils found throughout the area, improving drainage and creating better growing conditions.
Fill Dirt serves essential purposes for grading, filling low spots, and preparing construction sites. Properties in the Korbel area often require fill material to level building sites, raise planting areas above the water table, or fill in around new foundations. Our fill dirt is clean and compactible, suitable for both residential and commercial applications.
Common Uses for Earth Materials in Humboldt County
- Raised garden beds - Elevate plants above clay soils for better drainage
- Lawn establishment - Create level, nutrient-rich bases for new turf
- Grading and leveling - Prepare sites for construction and landscaping

Our sand selection meets the diverse needs of Korbel property owners, from construction projects to creating safe play areas for children. Each sand type is processed for its specific application, ensuring optimal performance and safety.
Mason Sand provides the fine, consistent texture required for masonry work, concrete finishing, and paver installation. This screened sand works well for setting pavers, leveling surfaces, and creating smooth mortar joints. Contractors throughout Humboldt County rely on quality mason sand for professional results.
Playground Sand creates safe, comfortable surfaces beneath play equipment and in sandbox areas. This washed sand is free of harmful materials and provides the cushioning needed for active children. Many Korbel families with young children use playground sand to create dedicated play areas on their rural properties.
Washed Sand serves multiple purposes around the property, from fill applications to mixing with other materials. The cleaning process removes fine particles and impurities, resulting in a versatile material suitable for many construction and landscaping uses.
Sustainable Aggregate Options
Crushed Concrete offers an environmentally responsible alternative to newly quarried materials. This recycled aggregate performs similarly to natural crushed stone while reducing construction waste and preserving natural resources. Many environmentally conscious Korbel residents choose crushed concrete for driveways, road bases, and drainage applications.
The recycled material compacts well and provides excellent drainage characteristics. Using crushed concrete aligns with the environmental values common among Humboldt County residents who appreciate sustainable building practices. This material works particularly well for rural driveways and private roads where aesthetics are secondary to function.
