Mason Sand for Patios in Sonoma, CA

If you are planning a patio, a paver walk or a driveway pad, you need gravel and aggregate delivery in Sonoma, CA that starts with the right base. California Rock Supply sells Class 2 base, bedding sand and decorative stone in bulk. This is the same Class 2 aggregate base that Caltrans uses to specify base material, and it is where every flatwork job here begins.

Sonoma sits in the Bay Area, where heavy clay shows up across the valley and hills. Clay moves when it gets wet, so the base under your pavers has to carry the load.

Ground and Conditions in Sonoma

A thin base is the first thing to fail under a paver patio. Clay soils here crack when dry and swell when wet, so a shallow layer of base rock pumps, shifts and lets the surface settle unevenly.

Once a paver drops, joints open and water gets in, which starts the same cycle again. The fix is a compacted base with enough depth and proper drainage, placed over firm subgrade.

Winter is the part of the year that decides your schedule. Most rain falls from late fall to spring, often in a few large atmospheric river storms. Water soaks into sandy ground fast but sits on clay and runs off slopes, so a saturated subgrade cannot be compacted.

The dry season from late spring into fall is the main window for base, driveway and paver work. Summer fog is common near the shore, but it is winter rain and wet clay that hold jobs up, not the fog.

Steep slopes also shed hillside runoff in winter storms, and drainage behind retaining walls and at culvert outlets needs clean stone to move that water away.

Materials for Sonoma Projects

Patio and flatwork work starts with bedding and base. Under pavers, slabs and Stone Screenings paths, Class 2 base is the standard. It compacts hard and stays put, and it is specified as Class 2 aggregate base. Recycled Class 2 base, made from Road Base or asphalt, does the same job under drives, patios and slabs. Some suppliers call that crushed miscellaneous base, or CMB.

Above the base, bedding material levels and supports the surface. Mason sand, also called masonry sand, is the go-to for brick and block work, paver joints and play sand. Washed sand, or concrete sand, handles leveling, bedding and the base under slabs. For a coarser bed, gravel sand blends coarse sand and fine gravel for leveling and bedding.

Drainage has to move water off the patio and away from the house. Drain rock and 3/4 inch drain rock are clean stone with no fines, so water passes through them. Use them in French drains, drywells and downspout runs. Rip rap, also called rock slope protection, armors slopes, creek banks and culvert outlets against winter runoff.

For the finished surface, Stone Screenings, or DG, packs firm for paths and patios. Driveway gravel surfaces an existing drive or tops a compacted base, and walkway gravel gives paths a finer, walkable finish. River rock and large river rock work in dry creek beds, borders and low-water beds.

Soils change over short distances here, so a sandy lot and a clay lot on the same street can need different subgrade prep. Topsoil and garden soil rebuild planting beds over clay or hardpan, and shredded mulch holds moisture through the long dry season.

Bulk material is ordered online, and you choose the quantity by the ton or by the yard. Those are different measures, so decide which one your job is priced in before you order. If you are unsure how much you need, the calculator sizes the load for your area and depth.

Questions About Gravel and Base in Sonoma

What gravel is best for a driveway in Sonoma?

Class 2 base is the standard for the compacted layer. It is specified as Class 2 aggregate base and compacts hard over clay. Top it with driveway gravel for the wearing surface. If drainage is the concern, 3/4 inch drain rock moves water because it has no fines.

How much material will my project need?

Use the calculator to size the load. Enter your area and the depth you are placing, and it works out the quantity in tons or yards. That keeps you from ordering short and having to stop the job, or having extra stone left sitting in the drive.
