Cobble and Bulk Aggregates for Calexico, CA

California Rock Supply handles gravel and aggregate delivery in Calexico, CA, by the ton. Class 2 base is the material most jobs here start with. It goes under driveways, parking pads and the compacted layer beneath pavers and slabs. Local ground is mostly sandy and gravelly, so it takes water fast.

When storm runoff is the problem, coarse stone does the work. That is where we start on most Calexico sites.

Materials for Calexico Projects

Short, intense storms push water off bare ground and into washes fast. Coarse, open-graded stone slows that water and holds soil in place. The list below runs coarsest to finest.

• RipRap, also called rock slope protection, armors slopes, creek banks and culvert outlets. Caltrans specifies placed rock on slopes this way, and it is the first line of defense against flash flood scour.
• Large River Rock builds dry creek beds and swales where runoff needs slowing before it leaves the property.
• 3/4" Drain Rock is clean stone with no fines, so water moves through it into French drains and drainage trenches.
• Class 2 Base, also called Class II base or Class 2 aggregate base, is the standard California base under drives, pads and patios. Caltrans specifies it as Class 2 aggregate base.
• Stone Screenings, or DG, packs firm for paths and patios laid over a compacted base.

Recycled base rock, made from Road Base or asphalt, does the same job as Class 2 base. Caltrans allows processed reclaimed asphalt and concrete in aggregate base, so ask if you want the recycled version.

Ground and Conditions in Calexico

Extreme summer heat and late-summer storms set the working window here. The cooler months are the best time to grade, compact and place stone. Plan your delivery for that window and the material behaves better.

Much of the Imperial Valley floor is sandy and gravelly and drains quickly. Old lake beds and flood plains hold silty clay that drains slowly. On clay, water ponds, so a drainage layer matters more than base thickness alone.

Frost is not a factor on the low desert floor, so base depth is set by load and drainage, not freeze-thaw. Wind is the other driver. Blowing sand and dust strip bare or disturbed ground, so cover exposed areas with stone or mulch as you go.

Quantities are ordered by the ton or by the cubic yard, depending on the material. Measure your area and depth first so you order the right amount. Class 2 base compacts, so account for that when you figure your volume.

A bulk truck needs clear access and a firm spot to dump. Mark any sprinkler lines, utilities or soft ground before it arrives. Lead time varies with the material and the season, so order ahead during the cooler months when crews are busiest.
