Bulk Aggregates near San Rafael, CA, 94912

Material Selection by Project Type

• Driveways: Use 3/4" crushed rock or road base for a compacted foundation. A base layer of at least 4 inches supports heavy vehicle traffic.
• Drainage: Choose Crushed Stone or drain rock without fines. These materials allow water to flow freely around foundations or in French drains.
• Patios and walkways: A compacted base of crushed stone topped with Stone Screenings or Natural Pea Gravel creates a stable, attractive surface.
• Landscape beds and soil work: Use top soil or garden soil for planting, and bark mulch or decorative stone for finished beds.

Local Conditions That Affect Material Choice

ZIP 94912 in San Rafael spans a mix of older suburban lots and newer hillside developments. Some properties sit on flat terrain, while others have sloped yards requiring drainage management.

Soil here varies from fast-draining Top Soil to denser clay in lower areas. In hilly sections, erosion control and stable base materials become more important.

Mild winters with occasional heavy rain mean materials with fines can soften if not properly compacted. Clean stone works best for areas needing consistent water flow.
