Bulk Gravel Delivery to San Pablo, CA

California Rock Supply stocks gravel and aggregate delivery in San Pablo, CA, from Class 2 base to sand, drain rock and topsoil. Soils here change over short distances, so the right bedding for a paver patio depends on what sits under it. Order the material that matches your ground and your finish.

Materials for San Pablo Projects

A paver patio or concrete slab only holds its grade if the bedding under it is right. That starts with Class 2 base, the standard California base material, specified by Caltrans as Class 2 aggregate base. It compacts hard and carries the load under pavers, slabs and Stone Screenings paths.

On top of that base, bedding does the leveling. Mason Sand sets brick, block and paver joints, and it doubles as play sand. Washed Sand levels and beds under slabs, and Washed Sand blends coarse sand with fine gravel for the same job where you want more bite.

For the finish, Stone Screenings, or DG, packs firm for paths and patios laid over a compacted base. 3/8" Crushed Stone tops a compacted base and beds pipe, while #89 Crushed Stone fills paver joints and tight bedding.

Ground and Conditions in San Pablo

The failure a thin base shows here is edge drop and rocking pavers. Clay soils in the Coast Range valleys crack when dry and swell when wet, so a base poured too thin moves with the moisture. A compacted Class 2 base at proper depth spreads that movement instead of passing it to your pavers.

Drainage follows the same logic. Most rain falls from late fall to spring, often in a few large winter storms and atmospheric rivers. Sandy ground takes it in; clay sits it on top. Under a patio or slab, a clean stone layer such as Drain Rock or 3/4" Drain Rock gives water somewhere to go.

Hillside runoff and slides on steep slopes are the winter risk, and the dry season from late spring into fall is the main window for base, driveway and paver work. Summer fog near the shore rarely holds a job up. Saturated clay does.

Delivery to San Pablo and the Surrounding Area

Bulk material is ordered by the ton or by the cubic yard, and the two are not the same number. A yard of Class 2 base weighs more than a yard of mulch, so check which unit the quantity was figured in before you order. Order online and we deliver to your site in San Pablo, in Contra Costa County, with coverage to Concord, Richmond, Antioch, San Ramon and Pittsburg.

Estimate your area first, then your depth, then convert. A patio base is measured in inches of compacted depth across the full footprint, and compaction pulls the loose volume down. The site calculator does that math for you if you would rather not work it out by hand.
