Mason Sand for Patios in Riverside, CA

Planning a paver patio, a driveway, or a drainage run? California Rock Supply handles gravel and aggregate delivery in Riverside, CA, and the material under your flatwork matters as much as the pavers on top. For most jobs here that means Class 2 base, the standard California base material, specified by Caltrans as Class 2 aggregate base. Pair it with mason sand and your patio sits on ground that holds.

The Inland Empire valleys sit on alluvial plains and fans, with soils running from sandy loam to clay. That mix decides how deep your base goes and how hard you compact it.

Materials for Riverside Projects

Under pavers, a patio is only as good as its bedding and base. Class 2 base carries the load; mason sand levels the surface so the pavers sit flat and stay put. Riverside contractors order both together for a patio, and the same pair for driveways, parking pads, and the base under Stone Screenings paths.

Class 2 base, also called Class II base rock or class 2 aggregate base, is the standard for driveways, parking pads, and the compacted base under pavers, slabs and Stone Screenings paths. Recycled class 2 base made from Road Base or asphalt does the same work, and Caltrans allows processed reclaimed asphalt and concrete in aggregate base. Some suppliers here call that crushed miscellaneous base, or CMB. Class 2 Base covers all of it.

For bedding over a compacted base, Mason Sand is the mason sand used for brick and block work, paver joints and play sand. Washed Sand goes under slabs and for leveling and bedding. Washed Sand is the coarser sand and fine gravel blend for the same jobs.

Once the pavers are down, Stone Screenings, or DG, packs firm for paths and patios. Driveway Gravel surfaces an existing drive or tops a compacted base.

Ground and Conditions in Riverside

A thin base fails the same way every time. The pavers rock, joints open, and edges settle. In Riverside the culprit is usually expansive clay, which swells when wet and shrinks and cracks when dry. Wetting that clay pushes up on slabs and paving.

The fix is depth and compaction. Excavate past the clay, build up with Class 2 base in lifts, and compact each lift before the next. Use enough depth that the load spreads across the base rather than punching into the soil below.

Rain arrives in a few winter storms and atmospheric rivers after a long dry season. It runs off hardscape and hard dry ground fast. Put drain rock behind retaining walls and at downspout runs so water leaves instead of sitting under your flatwork. The long, warm, dry season suits base and paver work for most of the year; winter storm days are the main interruption.

Delivery to Riverside and the Surrounding Area

Ordering online starts with quantity, and that means choosing between tons and cubic yards. Bulk material is usually sold by the ton. To convert, multiply your square footage by the depth in feet, divide by 27 for cubic yards, then use the material weight per yard to get tons. A thin bedding layer and a deep base lift land at very different numbers, so measure each layer on its own.

Give the driver a clear drop spot when the load arrives. Bulk delivery on a Riverside site means the truck needs room to reach the pile without crossing a fresh slab or a soft edge. Address, access and any gate width help.

We also deliver to Moreno Valley, Corona, Murrieta, Temecula and Jurupa Valley, so a single order can cover jobs on the same run.

Questions Riverside Buyers Ask

What gravel is best for a driveway in Riverside?

Class 2 base is the standard choice. It is specified by Caltrans as Class 2 aggregate base, and it compacts into the firm layer a drive needs. Top it with driveway gravel if you want a finished surface, or leave the base exposed. Recycled class 2 base made from Road Base or asphalt works the same way, and Caltrans allows processed reclaimed material in aggregate base.

How much material will my project need?

Work it out by volume, then convert to tons. Multiply square footage by depth in feet, divide by 27 for cubic yards, and apply the material's weight per yard. A paver patio takes a deep compacted Class 2 base plus a thin mason sand bedding layer, so figure those separately. Measure each layer and add a little for compaction and spillage.
