Buy 3/4 Inch Crushed Rock in Penn Valley, CA

California Rock Supply handles gravel and aggregate delivery in Penn Valley, CA, from Class 2 base for driveways and pads to drain rock, sand and topsoil. The rocky hillside ground here is often shallow over bedrock, so the material under your drive matters as much as the stone on top. Order online and we deliver.

Materials for Penn Valley Projects

Most drive and pad work here starts with Class 2 base, also called Class II base rock or class 2 aggregate base. It is the standard California base material, specified by Caltrans as Class 2 aggregate base, and it compacts into a firm layer under pavers, slabs and gravel surfacing. Recycled base rock made from Road Base or asphalt does the same job when you want a recycled option.

On top of that base, the choice is surface stone. Driveway Gravel is the usual pick for an existing drive or for topping a compacted Class 2 layer. 3/4" Crushed Stone is angular stone that locks together well on drive surfacing, drainage beds and construction entrances. If you want a finer, walkable finish on paths, Walkway Gravel is the better size.

Water has to go somewhere, so plan a clean stone layer with no fines. 3/4" Drain Rock and Drain Rock both work for French drains, drywells and downspout runs, letting water move through instead of pooling against your foundation. For a parking pad, a mix of Class 2 base below and crushed stone above keeps the surface tight.

Ground and Conditions in Penn Valley

Heavy winter rain is the driver. On the hillsides around Penn Valley, runoff moves fast over shallow soil and bedrock, while clay pockets hold water where the ground flattens. That shapes how you build: your drive and pads need to shed water, and runoff from slopes above needs a path around or under your work.

Practical answers are a crowned, compacted Class 2 base that stands up to winter, plus a drain rock layer at the low edge or in a trench. Erosion control matters too. Runoff down steep slopes, drives and road cuts can cut channels fast, and burned slopes shed debris when intense rain hits them. Rip rap on a slope, creek bank or culvert outlet armors those spots.

Timing matters as much as material. Work runs best from late spring into fall. Winter storms turn clay and steep drives to mud, so plan your base and surfacing before the rain returns.

Delivery to Penn Valley and the Surrounding Area

Bulk material arrives by the truckload, so it helps to know where you want the pile before we get there. Pick a spot a truck can reach and back out of, on firm ground, and keep it clear of overhead lines and anything you do not want buried. If the drive is steep or soft, say so when you order, and we can talk through where the load should land.

Order online and size your load by the ton or the cubic yard. A base layer needs a minimum depth of about 2 inches after compaction, and going thicker on soft ground saves you a second delivery later. We deliver across Penn Valley and the rest of Nevada County, including Grass Valley, Nevada City, Rough and Ready, North San Juan and Truckee.
