Crushed Stone, Sand and Gravel in Pinole, CA

California Rock Supply handles gravel and aggregate delivery in Pinole, CA for two kinds of buyers: contractors running full jobs and homeowners fixing one driveway or yard. Class 2 base carries most of that work. Soils here change over short distances, so the material under a pad matters as much as the material on top.

Materials for Pinole Projects

Grading and bed prep drive most orders in Pinole. Before a base goes down or a garden goes in, you need the right soil and fill underneath, and that choice decides how the finished surface holds up.

Start with Fill Dirt when you are raising grade or building up a pad. It goes down first and gets compacted before any Class 2 base covers it. For lawns and beds, Top Soil rebuilds planting areas over clay or hardpan. Raised beds and planters do better with Garden Soil, which is blended for roots rather than structural fill.

Over the soil, Class 2 base is the standard base material in California, specified by Caltrans as Class 2 aggregate base. It sits under pavers, slabs, driveways and Stone Screenings paths. Some suppliers also call it Class II base rock or CMB when it is made from Road Base or asphalt.

For the visible layers, buyers here ask for Stone Screenings for paths and patios, Driveway Gravel to surface a drive, and Drain Rock where water needs to move. Bedding and joints take Washed Sand or Mason Sand.

Ground and Conditions in Pinole

Most rain here falls from late fall to spring, much of it in a few large winter storms. Where that water goes decides what you build with and when you build.

Sandy ground near the shoreline drains fast, so a drainage layer and clean stone do their job quickly. Heavy clay in the Coast Range valleys and hills behaves the opposite way: it cracks when dry and swells when wet, and water sits on top or runs off. On a clay subgrade, compact fill and Class 2 base in lifts, and plan a real drainage path instead of hoping the soil takes the water.

Winter also brings hillside runoff on steep slopes and storm erosion along the shoreline. Armor slope toes and culvert outlets with RipRap, and use clean washed stone for french drains and behind retaining walls.

The dry season from late spring into fall is the window for base, driveway and paver work. Summer fog near the shore is not the problem; saturated clay is what holds a job up.

Questions About Ordering in Pinole

Can I order material by the ton for delivery in Pinole?

Yes. Base, sand, soil and stone are ordered by the ton or by the cubic yard, and the site calculator turns your measurements into a quantity. Measure the area, set the depth you need, and the tool does the conversion. That keeps a driveway or bed prep order close to what the job actually takes.

What stone should I use for drainage in Pinole?

Clean washed stone with no fines lets water pass, and fines are what clog a drain over time. Drain Rock and 3/4 inch drain rock work for french drains and drainage trenches, while 3/4 inch crushed rock suits drainage beds and construction entrances. On clay, add a filter fabric so soil does not migrate into the stone.
