Why Choose Our Aggregates in Mariposa County
Our aggregates are chosen for local performance: they resist freeze-thaw cycles at higher elevations, shed rain on steep driveways, and compact to create stable surfaces on granular soils. We test materials to make sure they perform in Mariposa County’s mixed geology and variable rainfall patterns.
- Free delivery across Mariposa County
- Local knowledge of soil types and slope management
- Materials graded for California climate and county conditions
Aggregates for Driveways, Roads, and Foundations
When you need durable aggregates for vehicular access or base layers, selecting the right material matters for longevity. Our team recommends specific aggregates based on slope, traffic, and underlying soils.
Driveway Solutions
For most rural drives in Mariposa County, we recommend a compacted base of 3/4 inch Crushed Stone topped with a wearing layer of Driveway Gravel. This combination handles light to moderate vehicle traffic and resists rutting when properly compacted.
Road Base and Crusher Run
Road Base and Crusher Run are excellent where a strong subbase is required. They interlock and compact well, making them a preferred choice for private access roads and heavy equipment staging areas.
- Best for heavy loads: Road Base, Crusher Run
- Best for quick drainage: #57 Stone, Drain Rock
- Sustainable option: Crushed Concrete
Decorative Rock, Walkways, and Landscape Aggregates
Mariposa County properties benefit from materials that match the rustic Sierra aesthetic while solving drainage and maintenance needs. Decorative aggregates add curb appeal and are low maintenance.
Decorative and Functional Uses
Use River Rock for water features and dry creek beds that mimic natural waterways. Pea Gravel and Walkway Gravel create comfortable, permeable walking surfaces. Decomposed Granite works well in xeric gardens and stabilized paths.
- Decorative accents: River Rock, Pea Gravel
- Stable walking surfaces: Walkway Gravel, Decomposed Granite
- Low maintenance groundcover options for dry summer months
Sands and Soil Products for Planting and Construction
Good soil and sand products are crucial for establishing lawns, planting native shrubs, and bedding pavers. We deliver screened topsoil and multiple sand types to match the project scale.
Topsoil and Fill Dirt
Our Topsoil is screened to remove large debris and blended for plant establishment. Fill Dirt is clean and compactable for grading and building pads.
Sand Options
Use Mason Sand for paver beds, Playground Sand for child-safe zones, and Washed Sand for drainage mixes or concrete batching onsite.
Drainage, Erosion Control, and Geotechnical Considerations
Mariposa County spans valley floors to granite outcrops; drainage and erosion control are critical in higher rainfall seasons and during spring runoff. Selecting angular, well-graded aggregates improves drainage and reduces erosion risk.
Recommended Products for Drainage
Drain Rock and #57 Stone are commonly used for French drains and perimeter foundation drains. For heavy runoff channels, River Rock (available in several sizes) helps direct flow while resisting displacement when properly installed with geotextile.
- French drains and foundation perimeters: Drain Rock, #57 Stone
- Surface erosion control: River Rock, Crushed Concrete for check dams
- Long term slope stabilization: layered approach using Fill Dirt and crushed stone
| Gravel Type | Best For | Size | Drainage |
|---|---|---|---|
| 3/4 inch Crushed Stone | Driveways, Base | 3/4 inch | Good |
| #57 Stone | Drainage, Trench Backfill | 1/2" to 1" | Excellent |
| Pea Gravel | Walkways, Play Areas | 3/8 inch | Fair |
| River Rock | Dry Creek Beds, Accents | Varies | Good |
| Crusher Run | Subbase, Compacted Pads | Mixed fines and stone | Moderate |
| Decomposed Granite | Paths, Xeriscape | Fine | Moderate |

Local Soil, Geology, and Climate Considerations
Mariposa County features granitic bedrock near Yosemite, alluvial valley soils, and pockets of clayey loam. These conditions influence drainage and compaction. Aggregates that resist clogging and allow percolation are preferred in many areas.
Soil Types and Installation Tips
On slopes with loam or clay, install geotextile under aggregates to prevent fines from migrating into drainage rock. In granitic or rocky soils, use well-graded base materials for compaction and stability. For frost-prone pockets, place a compacted base deeper than in warmer valley floors.
Climate and Seasonal Notes
Winter and spring runoff require robust drainage design. Summers are dry and hot, making low-water groundcovers like decomposed granite and river rock an effective choice to reduce irrigation needs.
Regional considerations like wildfire defensible space also affect material selection. Noncombustible gravel and rock mulches are commonly used around homes to meet defensible space recommendations.
