Fill and Base Material Delivered in Byron, CA

California Rock Supply handles gravel and aggregate delivery in Byron, CA, and most jobs here start with Class 2 base. It is also called Class II base, Class 2 aggregate base, or base rock. It goes under driveways, parking pads, and the compacted layer beneath pavers, slabs, and Stone Screenings paths.

Byron sits in Contra Costa County, where soils change over short distances. Sandy ground drains fast, and heavy clay holds water. That difference decides how much base you need and how you build it.

Delivery to Byron and the Surrounding Area

You order online and pick your quantity by the ton or the yard. If you are unsure how much material the job takes, the calculator on the product page sizes the load for you. Choose a delivery date at checkout, and a dump truck brings the material to your site.

Bulk delivery works best when the driver has a clear spot to dump. A driveway, a pad, or a graded area near the work keeps the pile close to where it gets spread. Byron is in Contra Costa County, and we also deliver to Concord, Richmond, Antioch, San Ramon, and Pittsburg.

Fill and base usually arrive together on larger jobs. Order the fill first so the grade is built up before the base goes down. That order keeps trucks from driving over finished base.

Materials for Byron Projects

Most work in Byron starts below the surface. Raising grade and building a pad takes fill dirt before any base material goes down. Fill dirt, also called structural fill, lifts a low spot, backfills around a foundation, or builds up a pad so the base sits at the right level.

Once the grade is set, Class 2 base goes on top and gets compacted. It is the standard California base material, specified by Caltrans as Class 2 aggregate base. Recycled base rock, made from Road Base or asphalt, does the same job under drives, patios, and slabs. Some suppliers call that crushed miscellaneous base, or CMB.

From there, the material follows the project:

• Driveway: Class 2 Base compacted first, then Driveway Gravel as the surface. Crusher Run works where you want a binding, compacting material.
• Patio or path: Stone Screenings over a compacted base. It packs firm and stays walkable.
• Drainage: 3/4" Drain Rock for French drains and drainage trenches. It is clean stone with no fines, so water moves through it. Drain Rock covers drywells and downspout runs.
• Planting: Top Soil for lawns and beds, and Garden Soil for raised beds.

Ground and Conditions in Byron

Soils here change over short distances. Sandy dune and beach soils sit along parts of the shoreline, and heavy clay is extensive in the Coast Range valleys and hills. Clay cracks when dry and swells when wet, so an under-built base moves with it.

That is why compaction matters more than thickness alone. On clay, a base laid loose over soft ground pumps and rutts once the rain arrives. Build the grade first with fill, then compact the Class 2 base in lifts.

Most rain falls from late fall to spring, much of it in a few large winter storms and atmospheric rivers. Sandy ground soaks it up quickly. Clay soils and slopes shed it. Winter rain and saturated clay are what hold jobs up, so the dry season from late spring into fall is the main window for base, driveway, and paver work.

Drainage belongs in the plan, not after the first storm. Clean stone like 3/4 inch drain rock moves water away from a base. Rip rap, also called rock slope protection, armors slopes and culvert outlets where runoff concentrates.
