3/4 Inch Drain Rock and Bulk Aggregates for Richmond, CA

California Rock Supply handles gravel and aggregate delivery in Richmond, CA, and the first stop for most jobs is the calculator. Enter your dimensions and it sizes the load by the ton or yard, so you order what the work needs instead of guessing. Class 2 base, washed stone, sand and soil all move the same way: you pick the date at checkout and a dump truck drops it on site.

Materials for Richmond Projects

Water is what drives material choice here. Winter storms dump a lot of rain in a short window, and it sits on clay soils instead of soaking away. That means drainage stone, not just base, gets specified on most jobs. Below, the washed and crushed materials are listed coarse to fine, with what each size actually does.

Starting with washed stone

For a French drain, a drywell or a downspout run, you want clean stone with no fines. Drain Rock and 3/4" Drain Rock are the washed sizes that let water pass instead of trapping it. On a lot with heavy clay, that gap between clean stone and a compacting material is the whole job.

Crushed sizes for beds and drives

Angular crushed stone locks together under a plate compactor, which is why it shows up in drainage beds and on drive surfacing. 3/4" Crushed Stone handles drainage beds and construction entrances. Step down to 3/8" Crushed Stone for pipe bedding and a finer top course.

Base under the hard surfaces

Every paver patio, slab and driveway starts with Class 2 Base. It is the standard California base material, specified by Caltrans as Class 2 aggregate base, and it compacts hard once it is watered and rolled. Some suppliers in the Bay Area also call it Class II base rock or CMB. Recycled Class 2 base, made from Road Base or asphalt, does the same job under drives and pads.

Delivery to Richmond and the Surrounding Area

You order online, choose your quantity by the ton or yard, and pick a delivery date at checkout. A dump truck then brings the load to your site. Coverage runs across Richmond and Contra Costa County, including Concord, Antioch, San Ramon, Pittsburg and Walnut Creek.

Bulk delivery means the truck has to reach the drop point, so plan the placement before the date arrives. Flag the spot where you want the pile dumped and keep the approach clear. On a tight residential street, a smaller load placed closer to the work saves you a long wheelbarrow push.

Ground and Conditions in Richmond

Soils change fast across this area. Sandy ground near the shoreline drains quickly, while the heavy clay in the Coast Range valleys and hills cracks when dry and swells when wet. Rain arrives mostly between late fall and spring, often in a few large storms, so what works in August may not work in January.

That shapes how you build. On clay, put clean drainage stone under and around the work so water has somewhere to go, and compact base in lifts so it does not pump when saturated. Steep slopes shed runoff fast and can slide in a big storm, which is where rip rap earns its place on banks and culvert outlets.

Timing matters as much as material. The dry season from late spring into fall is the main window for base, driveway and paver work. Summer fog near the shore is not a problem for compaction, but winter rain and saturated clay will hold a job up, so schedule the delivery for the window you actually have.

Questions from Richmond Buyers

Do you deliver Class 2 base to Richmond, CA?

Yes. California Rock Supply delivers Class 2 base to Richmond and the rest of Contra Costa County, including Concord, Antioch, San Ramon, Pittsburg and Walnut Creek. You order online, set the quantity by the ton or yard, and choose your delivery date at checkout. A dump truck brings the load to your site on that date.

What gravel is best for a driveway in Richmond?

Start with Class 2 base compacted as your structural layer, then top it with a surfacing gravel. On clay ground, the base does the load-bearing work, so build it thick enough and compact it in lifts. If your drive collects water, add a clean drainage stone edge or a French drain along the low side before you surface.
