Crushed Stone, Sand and Gravel in Graton, CA

If you are planning a driveway, a parking pad or the base under a patio, you are pricing gravel and aggregate delivery in Graton, CA. California Rock Supply sells Class 2 base, driveway gravel, sand and soil by the load and runs it out to Sonoma County jobs. Most of the work here starts with a compacted base. Get that layer right and everything above it lasts.

Materials for Graton Projects

Base comes first. Class 2 Base, also called Class II base rock, is the standard California material for driveways, parking pads and the compacted layer under pavers, slabs and Stone Screenings paths. Caltrans specifies it as Class 2 aggregate base, so a contractor and a yard hand mean the same thing when they say it.

On top of that base, Driveway Gravel surfaces an existing drive or caps fresh Class 2 base. It takes tire traffic and sheds water off the crown instead of letting it pool.

For paths and patios, Walkway Gravel gives a finer, walkable surface. Stone Screenings, or DG, packs firm over a compacted base and is the usual choice for garden paths and low-water ground cover.

Drainage stone is clean and washed, with no fines, so water moves through it. 3/4" Drain Rock, also sold as #57 stone, handles French drains and drainage trenches.

For bedding and joints, Washed Sand levels and beds under slabs, and Mason Sand goes into brick and block work and paver joints.

Ground and Conditions in Graton

Graton sits in Sonoma County, where soils change over short distances. Heavy clay is extensive in the Coast Range valleys and hills. That clay cracks when it dries and swells when it gets wet, which is hard on anything built on top of it.

Most of the rain arrives from late fall to spring, often in a few large winter storms. On clay it sits and runs off instead of soaking in. That is why a driveway here needs a base that drains, and why a minimum depth of a few inches of compacted Class 2 base matters more than the stone you see on top.

Hillside runoff and slides are a winter problem on steep slopes, so drainage runs and culvert outlets get attention before the rain. The dry season from late spring into fall is the window for base, driveway and paver work. Summer fog near the shore is a nuisance, not a delay. Saturated clay is what holds a job up.

Delivery to Graton and the Surrounding Area

Order online and size your load by the ton or the yard. A driveway that is longer or wider than you think will take more base than you estimate, so measure the area and the depth before you pick a quantity.

Bulk material arrives on a dump truck. Have the drop spot clear and reachable, with room for the truck to pull in and tip. If the pile is going on a drive you want to keep, lay down boards first.

We deliver across Graton and the rest of Sonoma County, including Santa Rosa, Petaluma, Rohnert Park, Windsor and Healdsburg.
