Bulk Aggregates for Patios in Auburn, CA

Planning a patio, a paver walkway, or a driveway pad in Auburn? Gravel and aggregate delivery in Auburn, CA starts with the material under the surface, not the one you see. California Rock Supply sells Class 2 base and the stone, sand and soil that go with it, delivered across Placer County.

Foothill ground here is rocky and often shallow over bedrock, with clay in some spots and fast-draining Stone Screenings in others. That mix decides how deep your base goes and how well your patio drains.

Ground and Conditions in Auburn

A thin base is the first thing to fail on a foothill patio. Pavers and slabs over an undersized layer of Class 2 base start to rock, settle, and hold water at the edges after a wet winter.

Heavy winter rain runs off fast over shallow soil and bedrock on slopes. Clay pockets hold that water instead of shedding it, so a pad that does not drain will pump mud up through the joints.

The fix is a compacted base built to the right depth for your soil and a drainage layer that gives runoff somewhere to go. On sloped lots, runoff from above also needs a path around the patio, not through it.

Erosion is real here too. Runoff down steep slopes, drives and road cuts moves material in heavy rain, and bare or recently burned slopes can move fast. Rip rap and cobble armor those spots.

Timing matters. Work runs best from late spring into fall, because winter storms turn clay and steep drives to mud. The higher towns can see snow delays in mid-winter, so plan flatwork and base work before the rain.

Materials for Auburn Projects

Most patios and flatwork here start with Class 2 base, also called Class II base or Class 2 aggregate base. It is the standard California base material, specified by Caltrans as Class 2 aggregate base, and it compacts hard under pavers, slabs and Stone Screenings paths. Order it as Class 2 Base.

Recycled base rock, also called recycled Class 2 base, does the same job under drives, patios and slabs. It is Class 2 base made from Road Base or asphalt, and Caltrans allows processed reclaimed asphalt and concrete in aggregate base. Some suppliers list crushed miscellaneous base, or CMB, alongside it.

Above the base, Stone Screenings, or DG, packs firm for paths and patios and works as low-water ground cover. Order Stone Screenings for a fine, firm surface.

For drainage, 3/4 inch drain rock and drain rock are clean stone with no fines, so water moves through them. Use them in French drains, drywells, downspout runs and behind retaining walls. Order 3/4" Drain Rock or Drain Rock.

Sand beds the flatwork. Mason sand, also called masonry sand, sets brick and block and fills paver joints, while washed sand, or concrete sand, levels and beds under slabs. Order Mason Sand or Washed Sand.

For planting around the patio, topsoil rebuilds lawn and bed areas over clay or hardpan, and shredded mulch holds moisture through the long dry season. Order Top Soil or Shredded Mulch.

Questions Auburn Buyers Ask

What gravel is best for a driveway in Auburn?

Start with Class 2 base, also called Class II base or Class 2 aggregate base. It compacts into a hard, stable layer that carries tires without rutting, which matters on foothill grades. Top it with driveway gravel for the wearing surface, or use 3/4 inch crushed rock where you want angular stone that locks together.

How much material will my project need?

It depends on the area you are covering and how deep the layer goes, which changes with your soil and drainage. Rather than guess, enter your measurements in the calculator and it returns the quantity to order. Then choose tons or yards at checkout and pick your delivery date.
