Fill and Base Material Delivered in Coulterville, CA

Winter rain hits these hills fast. Shallow soil sits over bedrock, clay pockets hold water, and runoff from slopes above needs somewhere to go. Gravel and aggregate delivery in Coulterville, CA starts with that problem. California Rock Supply stocks Class 2 base for pads and drives, plus clean drain rock that moves water instead of trapping it.

Delivery to Coulterville and the Surrounding Area

Order online and pick your quantity by the ton or the yard. Size the load with the calculator, then choose a delivery date at checkout. A dump truck brings the material to your site and drops it where you want it.

We deliver across Coulterville and Mariposa County, including Mariposa, Catheys Valley, Midpines, Hornitos and Fish Camp. Steep driveways and tight gates are common here, so note access when you order. Bulk loads need room for the truck to turn and dump.

Materials for Coulterville Projects

Most work here starts below the surface. Raise the grade, build the pad, then cap it. Fill dirt goes down first to build up a low spot or backfill against a foundation. Class 2 base goes on top, compacted in lifts, and carries the load from there.

For a driveway, start with fill dirt if the grade is low, then lay Class 2 base and compact it. Top it with driveway gravel for a finished surface. Class 2 base is the standard California base material, specified by Caltrans as Class 2 aggregate base. Recycled base rock works the same way and uses Road Base or asphalt.

For a patio or paver walk, Class 2 base under the pavers, then mason sand or washed sand for leveling and bedding. Stone Screenings, often called DG, packs firm for paths and patios laid over a compacted base.

For drainage, 3/4 inch drain rock has no fines, so water passes through. Use it in French drains, drywells and behind retaining walls. Rip rap armors slopes, creek banks and culvert outlets against winter runoff.

Ground and Conditions in Coulterville

Soils here are rocky and often shallow over bedrock. Some areas hold clay, others drain fast through Stone Screenings. That mix decides how much base you need and how well it compacts.

Clay holds water. An under-built base over clay pumps, shifts and fails once the wet season starts. Dig out soft spots, build up with fill dirt, then compact Class 2 base in lifts so the pad sheds water instead of soaking it up.

Runoff down steep slopes and road cuts is the other driver. Give water a path with drain rock and armor exposed slopes with rip rap. Work runs best from late spring into fall. Winter storms turn clay and steep drives to mud, and the higher towns can see snow delays in mid-winter.
