Bulk Aggregates for Patios in Roseville, CA

California Rock Supply handles gravel and aggregate delivery in Roseville, CA for two kinds of buyers: contractors setting pavers and flatwork all season, and homeowners building one patio in the backyard. Both need the same thing under the surface, a compacted Class 2 base that will not move after winter rain.

Placer County sits on deep valley alluvium, and that ground decides how much base your patio really needs.

Materials for Roseville Projects

Under pavers, slabs and Stone Screenings paths, the bedding layer is where most patios succeed or fail. The base carries the load, and the bedding layer lets you set each unit flat. Get the two confused and the surface rocks within a season.

Start with Class 2 Base, also called Class II base rock, the standard California base material and what Caltrans specifies as Class 2 aggregate base. It compacts hard and takes the weight of a patio, a driveway or a parking pad. Recycled base rock, made from Road Base or asphalt, does the same job under drives and slabs.

On top of a compacted base, bedding materials do different work:

• Mason Sand for paver joints and a thin, level bedding course under brick and block.
• Washed Sand for leveling and bedding under slabs and flatwork.
• Stone Screenings, or DG, for patios and paths that need a firm, fine surface that packs down.
• Washed Sand, a coarse sand and fine gravel blend that works for leveling and bedding.

For drainage at the edge of a patio, Drain Rock is clean stone with no fines, so water passes through it. 3/4" Drain Rock, also sold as #57 stone, does the same job in French drains and drainage trenches.

Ground and Conditions in Roseville

The failure you see here is a thin base. A patio built on a few inches over clay starts to settle and heave at the edges, and the pavers cup and shift. The cause is usually the ground below it, not the pavers.

This part of the Sacramento Valley is deep alluvium with heavy clay that cracks in summer, plus cemented hardpan a few feet down in places. Water cannot drain away, so it sits. That is why base depth and compaction matter more here than in free-draining ground, and why a drainage layer belongs in the plan.

Winter storms and atmospheric rivers bring most of the rain between late fall and spring, and on flat clay ground it ponds. Build the drainage in from the start. Rip rap, also called rock slope protection, armors creek banks and culvert outlets when high water runs.

The working window runs from late spring into fall. Winter rain leaves clay soft and sticky, and tule fog slows early starts, so most buyers pour base and set pavers in the dry months.

Delivery to Roseville and the Surrounding Area

Order online and pick the material by the ton or by the cubic yard. Bulk material is usually quoted in tons because that is how it is weighed and loaded. If your plan gives you cubic yards from a length, width and depth, convert before you order.

A rough estimate: multiply the area by the depth in feet to get cubic feet, divide by 27 for cubic yards, then convert to tons. Class 2 base runs heavier per yard than sand or mulch, so the two numbers are not interchangeable.

Bulk delivery drops the load where the truck can reach, so tell us about gate widths, low branches and soft ground at the time you order. California Rock Supply delivers across Placer County, including Rocklin, Lincoln, Granite Bay, Auburn and Loomis.
