River Rock, Stone and Soil Delivery in Brentwood, CA

Winter storms drop a season of rain in a few big pushes, and clay ground sheds it fast. That is why gravel and aggregate delivery in Brentwood, CA starts with drainage stone. California Rock Supply hauls Class 2 base, washed rock, sand and soil in bulk to jobs across the city.

Start with the water. Clean stone moves it away from your slab, your driveway edge and your retaining wall.

Materials for Brentwood Projects

Washed stone has no fines, so water passes straight through. That makes it the first order on most drainage jobs here. Match the size to the trench, then build the rest of the project.

Name the size and the job and the right material follows. For a French drain or a drywell, ask for 3/4 inch drain rock, sold in Caltrans stone numbering as #57 stone. It is washed, so it will not hold water.

Downspout runs and the drainage layer behind a retaining wall take drain rock. Want a heavier washed size for a construction entrance or a trench bottom? Use 3/4 inch crushed rock or #4 crushed stone.

Where runoff leaves a slope or a culvert, place RipRap. Caltrans calls placed rock on slopes rock slope protection. It holds the bank through a wet winter.

Once water is handled, build the base. Class 2 Base, also called Class II base rock or Class 2 aggregate base, is the standard California material under drives and pads. Caltrans specifies it as Class 2 aggregate base. Recycled Class 2 base made from Road Base or asphalt does the same job.

Top a compacted base with Driveway Gravel, or lay Stone Screenings for a path or patio. Both need a firm base under them.

Delivery to Brentwood and the Surrounding Area

Order online and pick your delivery date at checkout. Choose your quantity by the ton or by the yard, and use the calculator to size the load. A dump truck then delivers to your site in Brentwood.

Contra Costa County coverage runs from Brentwood to Concord, Richmond, Antioch, San Ramon and Pittsburg. One order can serve a job anywhere in that ring.

Have the drop spot clear and reachable before the truck arrives. Bulk stone, sand and soil come loose, so the driver needs room to spread the load where you want it. Small loads and full truckloads both ship the same way.

Ground and Conditions in Brentwood

Soils here change over short distances. Heavy clay that cracks when dry and swells when wet is common through the Coast Range valleys and hills, and sandy ground shows up along parts of the shoreline.

Clay drives the schedule. Rain sits on it or runs off it, so a saturated subgrade will not compact. The dry season from late spring into fall is the main window for base, driveway and paver work.

That timing decides your order date. Get the drainage stone on site first, then the base, then the surface material. Building over wet clay traps water and the base moves.

Hillside runoff and slides on steep slopes are the winter risk, and intense rain on recently burned ground can send debris flows. RipRap and clean drain rock on slopes and outlets are the practical answer.
