Bulk Gravel and Stone Delivery in Riverside County, CA
What should you order for a drive, pad or patio in Riverside County? Start with Class 2 base. California Rock Supply delivers gravel, stone and aggregate delivery in Riverside County, CA by the ton, and Class 2 base is the material most local jobs are built on.
It is specified locally under Caltrans Standard Specifications Section 26 as Class 2 aggregate base, the higher-strength grade, in a 3/4 inch or 1-1/2 inch maximum grading. The ground it goes on ranges from Top Soil to expansive clay that swells when wet.
Materials delivered in Riverside County
Order by size, coarsest to finest. The big sizes handle slope armor and heavy drainage, the middle sizes build drives and pads, and the fine sizes finish paths, beds and joints.
Class 2 base in depth
Class 2 aggregate base is the higher-strength grade of the two classes Caltrans allows. Class 3 is the lower-strength grade, and in Caltrans usage Class 5 is a subbase. Order the class the job calls for.
Some suppliers sell recycled Class 2 base or crushed miscellaneous base, which is Class 2 base made from Road Base or asphalt. Caltrans allows processed reclaimed asphalt and concrete in aggregate base. It goes down the same way under drives, patios and slabs.
Ground conditions across Riverside County
The county spans three ground zones, so the working season changes with where the job sits. Timing a delivery around that window matters as much as picking the material.
In the inland valleys around Riverside, Moreno Valley, Corona and Murrieta, the long warm dry season suits base and paver work most of the year. Soils run from Top Soil to expansive clay that swells when wet and shrinks and cracks when dry. That swelling is why a compacted Class 2 base goes under slabs and paving, at a minimum depth of 2 inches or more.
On the low desert around Indio and Cathedral City, sandy and gravelly fan soils take water quickly, but extreme summer heat and late-summer storms are the constraints. The cooler months are the best working window. Slow-draining silty clay on old lake beds and flood plains ponds water, so plan a drainage layer there.
In the mountain towns such as Anza and Mountain Center, the window runs late spring to fall. Freeze-thaw is a real design factor, with frost depth set by the local building department, 18 to 24 inches in mountain towns. Snow and frozen ground stop most base and excavation work in winter, and the spring thaw leaves unpaved ground soft.
Delivery across Riverside County
Order online and size the load by the ton or by the yard, whichever your takeoff uses. Bulk delivery arrives as a dump load, so have the drop spot clear and reachable by a truck before the driver gets there.
Coverage runs across the county, including Riverside, Moreno Valley, Corona, Murrieta, Temecula, Jurupa Valley, Menifee, Hemet, Indio, Perris, Lake Elsinore, San Jacinto, Beaumont and Cathedral City. Lead time depends on your address, the material and the size of the load, so build a little room into the schedule.
Give the driver a clear drop point and room to turn around. On hillside and mountain lots, say so when you order, because access shapes how the load is placed.
Choosing the right material
Ground next door shifts the choice, even a few miles away. In Orange County, alluvial plains and expansive clay look much like the inland valleys here, so the base and drainage call is similar: compacted Class 2 base under the slab and clean drain rock where water collects.
San Diego County spans the same three zones as Riverside, so the ground is similar and the decision comes down to the project. Drive and pad jobs take Class 2 base; slope and creek work takes rip rap.
Imperial County sits in the Colorado Desert, with sandy and gravelly fan soils and slow-draining silty clay on old lake beds. That pushes drainage higher up the list than it sits on most valley jobs here.
