Buy Fill Dirt in Vacaville, CA

If you are grading a pad, building up a low corner of the yard, or prepping beds before planting, you want gravel and aggregate delivery in Vacaville, CA that shows up ready to place. California Rock Supply supplies fill dirt, topsoil and Class 2 base for exactly those jobs, ordered online and dropped at your address.

Solano County ground swings between heavy clay and sandier pockets, so what goes under the surface matters as much as what you see on top.

Materials for Vacaville Projects

Most work here starts with grade. You raise or level the ground first, then cap it with the right surface material. That order is what keeps a drive, a patio or a bed sitting flat years later.

Soil, Fill and Mulch

• Fill Dirt raises grade, backfills against foundations and builds up a pad before Class 2 base goes down.
• Top Soil is screened for lawn and bed prep, and for building up planting areas over tight clay or hardpan.
• Garden Soil fills raised beds and planting areas where roots need loose, workable ground.
• Shredded Mulch goes on beds and tree rings to hold moisture through the long dry season.

Base and Driveway Material

Class 2 base is the standard California base material, also called Class II base, Class 2 aggregate base or base rock, and it is specified by Caltrans as Class 2 aggregate base. It compacts hard under driveways, parking pads, pavers and slabs. Recycled base rock and crushed miscellaneous base do the same job from Road Base or asphalt, which Caltrans allows in aggregate base.

For the visible layer, Driveway Gravel surfaces a drive or tops a compacted base. On paths, Walkway Gravel gives a finer, walkable finish, and Stone Screenings, or DG, packs firm for patios and low-water ground cover laid over base.

Drainage Stone, Sand and Decorative Rock

Clean washed stone moves water instead of holding it. 3/4" Drain Rock, also sold as #57 stone, fills French drains and drainage trenches, while Drain Rock handles drywells, downspout runs and the backfill behind retaining walls. For angular stone, 3/4 inch crushed rock and 3/8 inch crushed rock cover drainage beds and drive surfacing, and RipRap, called rock slope protection by Caltrans, armors slopes and creek banks.

Sand does the finish work. Mason Sand sets brick and block and fills paver joints, and Washed Sand, or concrete sand, levels and beds under slabs. Decorative jobs lean on River Cobble and Large River Rock for dry creek beds and borders, and Natural Pea Gravel for play areas and walkways.

Ground and Conditions in Vacaville

Rain here falls mostly from late fall to spring, often in a few large winter storms. Where that water goes decides what you build with.

Sandy ground takes it in quickly. Heavy clay, which is extensive in the Coast Range valleys, cracks when dry and swells when wet, so it sheds water and stays saturated long after the storm passes. That is why a compacted base layer and a clean drainage layer matter more here than in sandier parts of the Bay Area.

On slopes, winter runoff is the real test. Hillside water and slides are a known winter problem, and intense rain on recently burned slopes can move debris. Rip rap placed at culvert outlets and along banks slows that water and holds the slope.

The dry season from late spring into fall is your window for base, driveway and paver work. Winter rain and saturated clay are what hold a job up, not cold.
