Mason Sand for Patios in Orinda, CA

If you are bedding pavers for a patio, gravel and aggregate delivery in Orinda, CA starts with the right base and the right sand on top. California Rock Supply sells both in bulk. Every patio here sits on one of two things: a compacted Class 2 base or the heavy clay that swells when it gets wet. That choice decides how the flatwork holds up.

Ground and Conditions in Orinda

Coast Range clay is the reason patios settle out here. It cracks open in the dry season, swells when the winter rain arrives, and moves anything sitting on a thin base.

You see it as low spots, rocking pavers, and joints that open up. The fix is a compacted Class 2 base, spread and watered in lifts so it locks up hard before the bedding sand goes down.

Drainage matters just as much. Most rain falls between late fall and spring, often in a few large storms, and it sits on clay instead of soaking in. Slope the base away from the house and run a drain rock trench along the low edge.

The dry stretch from late spring into fall is your window for base, paver and driveway work. Winter rain and saturated clay are what stop a job.

Materials for Orinda Projects

Patio work is mostly a base and bedding job. The pavers are the visible part, but the layers under them carry the load, drain the water, and keep the surface flat.

Base and Bedding

Class 2 Base is the California base material, specified by Caltrans as Class 2 aggregate base. Contractors here also call it Class II base rock. It goes under patios, driveways, parking pads and DG paths, and it compacts to a firm, load-bearing layer.

Mason Sand is the bedding layer under pavers and brick. Screed it to an even thickness, set the units, and the sand fills the joints once you compact and water.

Washed Sand is the concrete sand used for leveling and bedding under slabs, and it is the sand to use if the patio ties into a pour.

For a loose patio surface instead of pavers, Stone Screenings packs firm and walks clean over a compacted base.

If you are building the pad up from nothing, Fill Dirt raises grade first. Set the top of the fill, then cap it with Class 2 base.
