Order Gravel, Stone and Soil in Corona, CA

Looking for gravel and aggregate delivery in Corona, CA? California Rock Supply delivers bulk material to driveways, building pads and backyard projects across Riverside County. Most jobs here start with Class 2 base, the standard California base material, laid over fill dirt where the grade needs lifting.

Corona sits on alluvial fans and terraces, so you get ground that ranges from Top Soil to clay. That mix decides how much fill and base your project needs before anything else goes down.

Delivery to Corona and the Surrounding Area

You order online, pick your material, and choose a quantity by the ton or the yard. If you are not sure how much you need, plug your measurements into the calculator and let it size the load for you.

At checkout you choose a delivery date, and a dump truck brings the material to your site. Bulk loads get placed where the truck can reach, so plan your access before the driver arrives.

We deliver across Corona and the rest of Riverside County, including Riverside, Moreno Valley, Murrieta, Temecula and Jurupa Valley. Whether your site is a new pad or an existing drive, the load arrives ready to spread and compact.

Materials for Corona Projects

Most projects in Corona start below the surface. Raising grade and building a pad means fill and sub-base first, then the finish material on top. Here is what to order for the work you have.

Building up a pad. Start with Fill Dirt to raise grade and backfill, then cap it with Class 2 Base. Class 2 base, also called Class II base rock or base rock, is the Caltrans-specified base for driveways, parking pads and the compacted layer under pavers and slabs.

Surfacing a driveway. Compacted Class 2 base carries the load, and Driveway Gravel gives you the finished surface. If you want a material that binds as it compacts, Crusher Run does the same job. Recycled base rock made from Road Base or asphalt works the same way under drives and slabs.

Paths and patios. Stone Screenings, or DG, packs firm over a compacted base and suits paths, patios and low-water ground cover. For a finer walkable surface, use Walkway Gravel.

Drainage. Clean washed stone moves water instead of holding it. Drain Rock and 3/4 inch drain rock handle French drains, drywells and downspout runs. For slope and creek bank armoring against winter runoff, order RipRap, which Caltrans calls rock slope protection.

Ground and Conditions in Corona

Corona sits on alluvial plains, fans and terraces. The soil runs from Top Soil to clay, and many basins and hills hold expansive clay that swells when wet and shrinks and cracks when dry.

That clay is the reason an under-built base fails. If you pour a slab or set pavers on ground that moves, the surface above it moves too. Fill dirt brings the grade up, and Class 2 base gives you a compacted layer that spreads load evenly.

Water is the other half of the story. Rain arrives in a few winter storms and atmospheric rivers after a long dry season, and it runs off hardscape and hard dry ground fast. Wetting expansive clay makes it swell under slabs and paving. A clean drain rock layer gives that water somewhere to go.

Burned hillsides and canyons above the city send debris flows in the first heavy storms, and hillside runoff can trigger slope failures. RipRap armors slopes, creek banks and culvert outlets against that runoff.

The long, warm, dry season suits base and paver work for most of the year. Winter storm days are the main interruption, so plan your delivery and compaction around them.
