Fill Dirt Delivery for Princeton, CA

Building a pad or raising grade in Princeton, CA? California Rock Supply handles gravel and aggregate delivery in Princeton, CA, and most jobs here start with fill dirt and Class 2 base. The valley floor soil does not always carry a slab or a loaded drive on its own.

Deep valley alluvium and heavy clay mean you build up before you build on. That is where the bulk materials come in.

Delivery to Princeton and the Surrounding Area

You order online, pick your material, and choose a quantity by the ton or the yard. If you are not sure how much you need, the calculator on the product page sizes the load for you. Pick your delivery date at checkout and a dump truck brings it to your site.

Princeton sits in Colusa County, and we deliver bulk loads across the county, including Colusa, Williams, Arbuckle and Stonyford. Give the driver a clear drop spot and room to spread the load.

Fill dirt and Class 2 base move in large volume, so plan the pile location before the truck arrives. A clean, level spot near the work keeps shoveling and hauling short.

Materials for Princeton Projects

Most jobs in Princeton start below finished grade. You raise the pad with fill dirt, compact it, then cap it with Class 2 base. That sequence is what keeps a driveway, shop pad or patio from settling later.

Fill dirt, also called structural fill, is the first load. It raises grade and backfills before the base goes down. Build the pad up in lifts and compact each one.

Class 2 base, also called Class II base rock or Class 2 aggregate base, is the standard California base material. Caltrans specifies it as Class 2 aggregate base, and it goes under pavers, slabs, Stone Screenings paths and driveways. Order it for anything that needs a compacted, load-bearing layer.

For a driveway, lay Class 2 base first, then top it with Driveway Gravel for the wearing surface. Many buyers also ask for Class 2 Base under a parking pad and use Crusher Run where a binding, compacting mix is wanted.

For a patio or path, compact Class 2 base and finish with Stone Screenings. It packs firm and walks well.

For a drain, use clean washed stone with no fines. Drain Rock and 3/4" Drain Rock are the usual picks for French drains and downspout runs. Washed stone lets water move instead of trapping it. Fill Dirt is the starting point for all of it.

Ground and Conditions in Princeton

Princeton sits on the Central Valley floor. The ground is deep valley alluvium with heavy clay that cracks in summer, and a cemented hardpan a few feet down across parts of the valley. Water stops there.

That hardpan is why an under-built base fails. If the pad is not raised and compacted properly, winter water sits on the clay and works its way under the slab or the drive. Raise the grade with fill first, then compact Class 2 base in thin lifts.

Most rain arrives from late fall to spring in winter storms and atmospheric rivers. On flat clay and hardpan ground, water ponds because it has nowhere to go. Build drainage in from the start.

The long, hot, dry season from late spring into fall is the main working window. Winter rain that leaves clay soft and sticky is what stops jobs, and dense tule fog can slow early starts.

Questions About Base and Supply in Princeton

What is the best base under pavers in Princeton?

Class 2 base. It is the standard California base material, specified by Caltrans as Class 2 aggregate base, and it compacts into a firm, load-bearing layer under pavers. Raise the grade with fill dirt first if the ground is low, then compact the base in thin lifts before setting the pavers.
