Material Selection by Project Type
Choosing the right material starts with the project.
- Driveways: Crusher run or Stone Screenings compacts into a firm, stable surface. A base layer of clean stone may be needed on soft ground.
- Drainage: Crushed Stone (3/4" or 1 1/2") allows water to move through without clogging. Avoid materials with fines for French drains or foundation drainage.
- Patios and walkways: Use a base layer of paver base or crushed stone, then top with Stone Screenings or sand. Proper compaction prevents settling.
- Landscape beds and soil work: Garden soil or top soil supports plant growth. Decorative stone or mulch finishes the bed and reduces weeds.
Local Conditions That Affect Material Choice
Marin County has varied terrain. The eastern side near the bay is flatter with clay-heavy soil that drains slowly. Western areas and the hillsides have faster-draining Top Soil.
Properties range from tight suburban lots in towns like San Rafael and Novato to larger rural parcels with long driveways. Slopes and soft ground after rain can affect material stability and delivery access.
Freeze-thaw cycles are rare, but heavy winter rains require materials that drain well and hold their shape. Compaction and base preparation matter more on clay soils.
Delivery and Access in Marin County
Delivery planning in Marin County depends on the property layout, truck access, and drop location.
Rural driveways, tight turns, steep grades, soft ground, and overhead clearance can affect the truck size or unloading point.
Before scheduling, customers should know where the material should be dropped, whether the truck can turn around, and whether the driveway or job site can handle the load. American Rock Supply serves much of Marin County with bulk delivery.

Frequently Asked Questions
Common questions about gravel and aggregate delivery in Marin County, CA
Does American Rock Supply deliver throughout Marin County?
Yes, we deliver to much of Marin County, including San Rafael, Novato, Mill Valley, and surrounding communities. Delivery access may vary for very remote or steep properties.
What aggregate is best for a residential driveway in Marin County?
Crusher run or Stone Screenings works well for most driveways. Both materials compact firmly and handle the region's clay and loam soils. A base layer of clean stone may be needed if the ground is soft.
What is the difference between crusher run and Crushed Stone?
Crusher run contains fines that bind the material when compacted, making it stable for driveways and base layers. Crushed Stone has no fines and allows water to drain through it, which is better for drainage projects.
What material works best for drainage around a foundation?
Crushed Stone, typically 3/4" or 1 1/2", is ideal for French drains and foundation drainage. It does not clog and lets water move away from the structure.
How do I figure out how much material I need?
Contact our team with the rough dimensions of your project area and the type of work. We can help estimate the volume needed without requiring exact formulas.
