Crushed Stone, Sand and Gravel in Kenwood, CA

If you are grading a pad, building up beds, or setting a driveway in Kenwood, CA, you need the right material on site before the work starts. California Rock Supply delivers gravel and aggregate delivery in Kenwood, CA, from Class 2 base for the subgrade under a drive or slab to topsoil and fill dirt for everything above it.

Soils here change fast. Heavy clay sits in the Sonoma County valleys and hills, and it swells when wet, so what you put on top of it decides how the job holds up.

Materials for Kenwood Projects

Most jobs around here start with the ground, not the surface. That means fill dirt to raise grade, then Class 2 base compacted on top of it. Class 2 base is the standard California base material, specified as Class 2 aggregate base, and it is what goes under driveways, parking pads, pavers and slabs.

Once the grade is set, the surface and planting layers go down. Here is how the main families break out for a Kenwood project.

Recycled base rock, sometimes called recycled class 2 base or CMB, does the same job as Class 2 base under drives and patios. Caltrans allows processed reclaimed asphalt and concrete in aggregate base, so it is a normal choice for subgrade work. Order it if you want the recycled version of the same material.

For path and patio surfaces, Stone Screenings packs firm and fine. It goes over a compacted base, not straight onto raw clay. For drainage runs, 3/4 inch drain rock is clean stone with no fines, so water moves through it instead of sitting. Rip rap armor slopes and culvert outlets where winter runoff cuts.

Sands cover the finer work. Washed sand beds and levels under slabs, and mason sand handles brick and block work and paver joints. Natural Pea Gravel and river cobble finish play areas, dry creek beds and decorative beds where you want round stone instead of angular.

Ground and Conditions in Kenwood

Kenwood sits in the Coast Ranges, where rain arrives from late fall through spring, often in a few large winter storms. That pattern drives most material decisions here. Sandy ground takes water in quickly. Clay soil in the valleys and hills does not, so water sits on it or runs off the slope.

On flat clay, that means drainage has to be planned, not added later. A clean stone layer under a slab or behind a retaining wall gives water somewhere to go. On graded ground, fill dirt and base go down in lifts and get compacted, because loose material under a drive will move once it soaks.

Slopes are the other concern. Hillside runoff and slides show up on steep ground in winter storms, and culvert outlets take a beating. Rip rap placed at an outlet slows the water before it cuts a channel. The dry season from late spring into fall is the main window for base, driveway and paver work, since winter rain and saturated clay are what hold jobs up.

Delivery to Kenwood and the Surrounding Area

Order online and pick your quantity by the ton or by the yard. The calculator sizes the load for you, so you are not guessing at how much a driveway or a bed takes. You choose a delivery date at checkout, and a dump truck brings the material to your site.

Have the drop spot clear before the truck arrives. A firm, level area near the work keeps the load where you want it and keeps the truck off soft ground. If the site is tight or the access is steep, tell us where the material should land so it does not have to be moved twice.

California Rock Supply delivers across Sonoma County and the Bay Area, including Santa Rosa, Petaluma, Rohnert Park, Windsor and Healdsburg.
