Materials for San Jacinto Projects

Most San Jacinto projects start below grade. Fill dirt raises a pad or backfills a wall before anything else goes down, and it is the first load on many jobs.

Topsoil comes next. Screened topsoil builds up lawns and beds over the clay and sandy native ground, giving roots something to work into. Garden soil, also called planter mix, goes into raised beds and planting areas where you want a lighter mix.

Once grades are set, Class 2 base is the standard base material here, specified by Caltrans as Class 2 aggregate base. It compacts hard under driveways, parking pads and the base beneath pavers, slabs and Stone Screenings paths. Recycled base rock, made from Road Base or asphalt, does the same job, and Caltrans allows processed reclaimed asphalt and concrete in aggregate base. Some suppliers call that material crushed miscellaneous base, or CMB.

For finished surfaces, Stone Screenings, or DG, packs firm for paths and patios. Driveway gravel tops an existing drive or a compacted base, and walkway gravel gives paths a finer, walkable surface. Driveway Gravel and Walkway Gravel both go down over Class 2 base.

Ground and Conditions in San Jacinto

Rain here arrives in a few winter storms and atmospheric rivers after a long dry season. It runs off hardscape, hard dry ground and clay fast, which is why drainage and compaction get planned together rather than separately.

The bigger issue is expansive clay. It swells when wet and shrinks and cracks when dry, so wetting it under a slab or a driveway pushes the paving around. Compact your base in lifts and keep water from sitting under the edges. A clean drainage layer helps. For that, drain rock and 3/4 inch drain rock, also called #57 stone, carry water with no fines to clog the voids.

Burned hillsides and canyons above the valley shed debris flows when the first heavy storms hit, and slope failures follow winter runoff. Rip rap, called rock slope protection in Caltrans usage, armors slopes, creek banks and culvert outlets against that. The long, warm, dry season suits base and paver work most of the year, with winter storm days the main interruption.

Delivery to San Jacinto and the Surrounding Area

Order online and choose your quantity by the ton or by the cubic yard. Bulk material arrives on a dump truck and is tipped where you want it, so have the drop spot clear and firm before the truck reaches the site.

Measure the area and depth first so the load matches the job. Fill dirt and base go down in lifts, and a minimum depth of 2 inches applies to most surface layers. We deliver across San Jacinto and the rest of Riverside County, including Riverside, Moreno Valley, Corona, Murrieta and Temecula.
