Bulk Gravel and Stone Delivery in Yolo County, CA
For gravel, stone and aggregate delivery in Yolo County, CA, start with Class 2 base. It is the standard California base material, called class II base or base rock on most job sites, and it goes under driveways, parking pads, pavers and slabs. California Rock Supply sells it by the ton and delivers bulk loads across the county. On the deep valley alluvium here, heavy clay and cemented hardpan stop water from draining away, so what you put under a slab matters as much as the slab itself.
Materials Delivered in Yolo County
Order by the job you are building, not by the label on the pile. The materials below cover most drive, patio, drainage and planting work in the county.
Class 2 Base
Class 2 base is the higher-strength grade of California aggregate base, and Class 3 is the lower-strength grade. Both are specified by Caltrans Standard Specifications Section 26 in a 3/4 inch or 1-1/2 inch maximum grading. Class 2 is the common base under drives, pads and pavers. The spec also allows processed reclaimed asphalt and concrete, which is why recycled Class 2 base is widely sold and works the same way.
Recycled and Related Base Materials
Recycled base rock, also called recycled class 2 base, is Class 2 base made from Road Base or asphalt. Use it the same way under drives, patios and slabs. Crushed miscellaneous base, or CMB, is a recycled base name some California suppliers use alongside Class 2 base for drive and pad subgrade. Crusher Run is the choice where you want a compacting, binding material, though local buyers more often ask for Class 2 base for the same job.
Drainage Stone and Decorative Rock
For water that has nowhere to go, 3/4" Drain Rock and 3/4" Crushed Stone handle French drains, drainage trenches and construction entrances. River Cobble and Large River Rock work in dry creek beds, borders and swales where runoff needs slowing. Natural Pea Gravel covers play areas and bedding, and Mason Sand and Washed Sand handle paver joints, bedding and leveling under slabs.
Ground Conditions Across Yolo County
The county sits on the Central Valley floor, on deep valley alluvium. In the flood basins and along the valley edges, that means heavy clay that cracks in summer. Across parts of the valley there is also a cemented hardpan a few feet down that stops water moving deeper.
That ground changes how you build. Heavy clay and hardpan hold water instead of passing it, so a base laid straight on native soil traps moisture and moves under load. Excavate to a firm layer, compact in lifts, and put a drainage layer where water collects. Riprap and cobble protect creek banks and culvert outlets when winter storms push water high.
Most rain arrives from late fall to spring in winter storms and atmospheric rivers. On flat clay and hardpan, water ponds because it has nowhere to go, so drainage has to be built in rather than hoped for. 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.
Delivery Across Yolo County
Order online and pick your quantity before checkout. Bulk material is sold by the ton or by the cubic yard, and the square footage you are covering, the depth you need, and the density of the material set the load size.
Delivery covers Davis, Woodland, West Sacramento, Winters, Esparto, Knights Landing, Clarksburg, Guinda, Brooks and Capay. A bulk delivery arrives as a dump load placed where the truck can safely reach, so think about access and where you want the pile before it lands. Measure the area first, then size the order around it.
Choosing the Right Material
Neighboring counties show how much the base and drainage choice shifts with the ground. Solano County spans the Bay Area and the Sacramento Valley, so part of it sits on the Central Valley floor and part in the Coast and Coast Ranges. On the valley side the ground is similar to Yolo County, while the coastal side changes what you need for drainage.
Colusa County also spans the Central Valley floor and the Coast and Coast Ranges. Its valley ground matches Yolo County, so the same Class 2 base and drainage layers apply, and the differences there come down to typical projects rather than soil.
Sacramento County sits in the Sacramento Valley on the same deep valley alluvium, with the same heavy clay and cemented hardpan. Treat it as similar ground and compare projects instead of materials. In all four counties, clay and hardpan are what decide your base depth and whether you need a drainage layer at all.
