Crushed Stone, Sand and Gravel in Crockett, CA

California Rock Supply handles gravel and aggregate delivery in Crockett, CA, and the list starts with Class 2 base. That is the Caltrans Class 2 aggregate base local crews spec under drives, pads and pavers. We also stock the soil, sand and stone that finish the job.

Soils here change fast, from sandy shoreline ground to heavy clay that swells when wet. The right material depends on what your ground does with winter rain.

Materials for Crockett Projects

Most jobs in Crockett start with dirt, not stone. If your yard sits low or the native ground is hard clay, you build grade first with Fill Dirt, then compact a base over it. Get the fill right and everything above it stays put.

For lawns and beds, Top Soil builds up planting areas over clay, hardpan or sandy native soil so roots have something to work in. Raised beds and planters do better with Garden Soil, which holds moisture through the dry months. Finish beds with Shredded Mulch to hold that moisture in.

Once grade is set, the structural layers go down:

• Class 2 Base, also called Class II base rock, for driveways, parking pads and the compacted base under pavers and slabs.
• Driveway Gravel to surface an existing drive or top a compacted base.
• Washed Sand for leveling and bedding under slabs and pavers.
• Mason Sand for brick and block work and paver joints.

Decorative and drainage work rounds out an order. Stone Screenings, or DG, packs firm for paths and patios. 3/4" Drain Rock and Drain Rock carry water away from walls and footings. River Cobble and RipRap handle beds and slope armoring.

Ground and Conditions in Crockett

Nearly all the rain here falls from late fall to spring, much of it in a few large winter storms. Sandy ground soaks it up quickly. Heavy clay soils swell when wet and crack when dry, so water sits on top or runs off instead of draining.

That changes how you build. On clay, go deeper with Class 2 base and compact it in lifts, because a thin layer over wet clay will move. Put a clean stone drainage layer under the base where water has nowhere to go. Drain rock has no fines, so water passes through it.

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; winter rain and saturated clay hold jobs up. Steep slopes above town also shed runoff fast in big storms, which is where RipRap and cobble earn their place.

Delivery to Crockett and the Surrounding Area

Order online and choose your quantity by the ton or by the cubic yard. Bulk material arrives in a dump truck and is tipped where you want it, so have the drop spot cleared and the path to it wide enough for the truck.

Think about where the pile lands before it arrives. A load set too far from the work means wheelbarrow trips all day. Set it close, but off any finished surface.

We deliver across Crockett and Contra Costa County, including Concord, Richmond, Antioch, San Ramon and Pittsburg.

Questions Crockett Buyers Ask

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

Yes. Every bulk material we sell can be ordered by the ton, and sand, soil and gravel can also be ordered by the cubic yard. Use the calculator on the product page to convert your area and depth into a quantity. If you are unsure, size the base at a minimum depth of 2 inches and round up slightly, since compaction settles the material.

What stone should I use for drainage in Crockett?

Use clean washed stone, not base material. Drain Rock and 3/4" Drain Rock have no fines, so water moves through instead of pooling. For French drains and downspout runs, line the trench and fill it with drain rock. For a drainage bed under a slab or paver base, 3/4" Crushed Stone works well. Clay ground drains slowly, so give the water a clear path out.
