Cobble and Bulk Aggregates for Lodi, CA

California Rock Supply handles gravel and aggregate delivery in Lodi, CA by the ton. Lodi sits on deep valley alluvium, where heavy clay and a cemented hardpan a few feet down stop water from draining away. That ground decides how deep your base goes. Class 2 base over prepared subgrade is where most drive and pad jobs start here.

Materials for Lodi Projects

Most of San Joaquin County is flat, so the erosion work in Lodi is about moving water, not hillsides. Winter storms and atmospheric rivers push creeks and levee banks hard, and flat clay ground holds what falls. Coarse stone is how you armor those edges and keep runoff moving.

Rip rap, also called rock slope protection, is the heavy answer. It goes on creek banks, swale edges and culvert outlets where winter flow scours soil away. Placed stone at this size absorbs the energy instead of letting water cut underneath.

Large River Rock and River Cobble work better where the bank needs to look finished. Cobbles slow runoff in dry creek beds and swales, and both sizes hold soil in place on gentler slopes. Use them where water is seasonal rather than violent.

For water that has to leave a site fast, Drain Rock and 3/4" Drain Rock are clean washed stone with no fines, so water passes straight through. They suit French drains, drywells and downspout runs on ground that ponds.

Every job still needs a base under it. Class 2 base, also called Class II base rock or Class 2 aggregate base, is the standard California base material, specified by Caltrans as Class 2 aggregate base. You can also order Class 2 Base made from Road Base or asphalt, which Caltrans allows in aggregate base.

Ground and Conditions in Lodi

The working window runs from late spring into fall, through the long, hot, dry season. That is when clay subgrade is workable and compaction holds. Winter rain turns the same clay soft and sticky, and dense tule fog can slow an early start.

Frost is not part of base-depth planning here. What matters is drainage. Rain arrives from late fall to spring, and on flat clay and hardpan it has nowhere to go, so it ponds. Build the drainage layer in from the start rather than adding it after the first wet winter.

In the flood basins and along the valley edges, clay cracks open in summer. Water runs into those cracks and softens the subgrade under a pad. Excavate to firm ground, compact in lifts, and cap with Class 2 base before pavers, slabs or a Stone Screenings path go down.

Delivery to Lodi and the Surrounding Area

Order online and choose your quantity by the ton or by the cubic yard. Bulk delivery covers Lodi and the rest of San Joaquin County, including Stockton, Tracy, Manteca, Lathrop and Ripon. Typical lead time depends on your material and the season, so schedule around your pour or compaction date.

On delivery day, clear a route the truck can actually use. Bulk trucks need room to turn and a firm, dry surface to stand on. Have your dump spot marked and your base depth figured out before the load arrives.
