Bulk Aggregates for Patios in Alameda, CA

If you are building a patio, you need gravel and aggregate delivery in Alameda, CA that shows up ready to compact. California Rock Supply stocks Class 2 base for the bedding layer under pavers and flatwork. On the island side, sandy ground drains fast, but the clay soils in the hills hold water and move under a load, so the base layer has to carry the patio, not the soil beneath it.

Ground and Conditions in Alameda

A thin base is where patios fail here. Clay soils in the Coast Range valleys and hills crack when dry and swell when wet, so a shallow bedding layer pumps and the pavers rock out of plane.

The fix is a thicker compacted base and a drainage layer that gives winter storm water somewhere to go. Most rain arrives from late fall to spring in a few large storms, and it sits on clay instead of soaking in. Sandy shoreline ground drains faster but still needs confinement.

Hillside runoff and slides on steep slopes are a real winter driver, so plan the drain before the base goes down. The dry season from late spring into fall is the main window for base, driveway and paver work. Summer fog near the shore does not stop a job; saturated clay does.

Materials for Alameda Projects

Under pavers, slabs and Stone Screenings paths, the bedding layer does the work. Class 2 base, also called Class II base or Class 2 aggregate base, is the standard California base material and is specified by Caltrans as Class 2 aggregate base. It compacts hard and stays put under flatwork. Order it as Class 2 Base.

Recycled base rock, or recycled Class 2 base, is made from Road Base or asphalt and works the same way under drives, patios and slabs. Caltrans allows processed reclaimed asphalt and concrete in aggregate base. Some suppliers also call this crushed miscellaneous base, or CMB. Both route to the same product.

Where you want a binding, compacting material and the yard is out of base, Crusher Run does the same job. California buyers more often ask for Class 2 base for subgrade.

Above the base, the surface choice matters. Driveway Gravel surfaces an existing drive or tops a compacted base. Walkway Gravel gives paths and garden beds a finer, walkable finish. Stone Screenings, or DG, packs firm and is the go-to for patio and path fines laid over a compacted base.

Sand and drainage round out a patio build. Mason Sand fills paver joints and handles brick and block work. Washed Sand levels and beds under slabs. Drain Rock handles French drains, drywells and the drainage behind a retaining wall.

Delivery to Alameda and the Surrounding Area

You order online, choose your quantity by the ton or by the yard, and pick a delivery date at checkout. A dump truck then delivers the load to your site. Alameda County jobs are served, including Oakland, Fremont, Hayward, Berkeley and San Leandro.

Tons or yards? Base and sand are usually ordered by the ton, while decorative stone and some soils are easier to plan by the yard. The material calculator sizes the load for you, so you order once and get the right amount.

Bulk delivery drops where the truck can reach. On a patio job, that usually means staging the base close to the excavation and keeping the sand and drain rock separate. Access matters on the island and in the hills, so note the drop spot when you order.
