Crushed Stone, Sand and Gravel in Walnut, CA

California Rock Supply handles gravel and aggregate delivery in Walnut, CA, from Class 2 base and driveway gravel to sand, topsoil and decorative rock. If your drive, parking pad or paver base is the job, start with the material this market specifies by name.

Walnut sits on alluvial ground that runs from sandy loam to clay, so what you put under a slab or a drive matters as much as what you see on top.

Materials for Walnut Projects

Driveway work leads here, and it starts below the surface. Class 2 Base is the standard California base material, specified by Caltrans as Class 2 aggregate base. It compacts hard under drives, parking pads and the base beneath pavers, slabs and Stone Screenings paths.

Recycled base rock is the same Class 2 material made from Road Base or asphalt, and Caltrans allows processed reclaimed asphalt and concrete in aggregate base. Some suppliers list it as crushed miscellaneous base, or CMB, for the same subgrade work. Either one goes down the same way.

On top of that base, Driveway Gravel resurfaces an existing drive or caps a compacted base. For finer work, Walkway Gravel gives paths a walkable surface, and Stone Screenings packs firm for paths, patios and low-water ground cover.

Drainage stone is the other family worth ordering in the same load. 3/4" Drain Rock has no fines, so water moves through it in French drains and drainage trenches. Drain Rock covers drywells, downspout runs and the backfill behind retaining walls.

Sand and soil round out most orders. Mason Sand sets brick and block and fills paver joints, while Washed Sand levels and beds under slabs. Top Soil builds up lawn and bed areas over clay or hardpan.

For decorative beds and borders, River Cobble and Natural Pea Gravel cover ground and slow runoff where a dry creek bed or swale is doing the work.

Ground and Conditions in Walnut

Rain here arrives in a few winter storms, then the ground sits dry for months. When those storms land, water runs off hardscape, dry ground and clay fast.

Expansive clay is the part that catches people out. It swells when wet and shrinks and cracks when dry, and that movement happens directly under slabs and paving. Wetting it makes it swell.

The practical answer is depth and compaction. A minimum depth of 2 inches of Class 2 base is a starting point, and thicker lifts under a drive give the clay less room to move your surface. Compact in lifts rather than one deep pour.

Where water has nowhere to go, a clean drainage layer of 3/4" drain rock or drain rock moves it away from the base instead of letting it sit. On hillside edges, placed rock armors slopes and culvert outlets against winter storm runoff.

Timing is easy for most of the year. The long, warm, dry season suits base and paver work, and winter storm days are the main interruption.

Delivery to Walnut and the Surrounding Area

Order online and choose your quantity by the ton or the cubic yard. Bulk material arrives on a dump truck and is tipped where you want it, so have the drop spot clear and reachable before the truck shows up.

Walk the route first. Low branches, parked cars and a soft edge on the drive can stop a loaded truck, and moving the pile afterward costs you more time than clearing the path beforehand.

California Rock Supply delivers across Walnut and Los Angeles County, including Los Angeles, Long Beach, Santa Clarita, Glendale and Lancaster. Put the material where you want it and leave the hauling to us.
