Fill Dirt Delivery for San Rafael, CA

For gravel and aggregate delivery in San Rafael, CA, start with Class 2 base. It is the standard California base material, the local name for the compacted layer under driveways, parking pads, pavers and slabs. California Rock Supply delivers it across Marin County.

Soil here changes fast. Sandy ground near the shoreline drains quickly, while clay in the valleys swells when wet. That difference decides how much base your project needs.

Delivery to San Rafael and the Surrounding Area

You order online and choose a quantity by the ton or the yard. The calculator sizes the load when you are not sure how much to take. Pick your delivery date at checkout, and a dump truck brings the material to your site.

Bulk delivery reaches San Rafael and the rest of Marin County, including Novato, Mill Valley, Larkspur, San Anselmo and Corte Madera. Trucks need a clear path and a firm spot to dump. Loose or saturated ground near a slope is worth checking before the load arrives.

Materials for San Rafael Projects

Most jobs here begin below grade. Fill dirt raises a low pad or backfills a cut before anything else goes down. Once the grade is right, Class 2 base goes on top and gets compacted. That order matters on clay, where an under-built base moves.

For a driveway, use fill dirt to correct the grade, then Class 2 base, then driveway gravel on top. Recycled base rock works the same way and Caltrans allows processed reclaimed asphalt and concrete in aggregate base. Some suppliers call it crushed miscellaneous base, or CMB.

For a patio or paver area, Class 2 base carries the load and washed sand levels the bedding under the units. Mason sand fills the joints. For a drain, use drain rock, a clean stone with no fines so water moves through it. Stone Screenings, or DG, suits paths and patios over a compacted base.

Ground and Conditions in San Rafael

The soil under a San Rafael job is the first thing to read. Sandy ground near the shoreline drains fast. Heavy clay in the Coast Range valleys and hills cracks when dry and swells when wet, so it holds water and moves under a load.

That is why an under-built base fails on clay. Class 2 base needs to go down over a stable, well-drained subgrade and be compacted in lifts. Where water collects, a drain rock layer or a French drain relieves it before the base goes in.

Most rain falls from late fall to spring, often in a few large winter storms. It soaks into sand quickly but sits on clay and runs off slopes. Winter also brings hillside runoff and slides on steep ground. The dry season from late spring into fall is the main window for base, driveway and paver work.
