Bulk Aggregates for Patios in Sunland, CA

California Rock Supply handles gravel and aggregate delivery in Sunland, CA for two kinds of buyers: contractors setting paver patios and flatwork, and homeowners building the same projects on their own. Both usually start with Class 2 base, the standard California base material, and both care about how the ground under the work behaves.

Sunland sits on alluvial ground in Los Angeles County, with soils that run from sandy loam to clay. Expansive clay is common here, and it swells when it gets wet.

Ground and Conditions in Sunland

A thin base is the problem we hear about. A paver patio or slab laid over a shallow, poorly compacted layer starts to dip and rock within a season or two, and the joints open up.

The reason is the clay underneath. Expansive clay swells when winter rain soaks it and shrinks and cracks through the long dry season. That movement travels straight up into anything thin above it.

The fix is a properly compacted Class 2 base built to the depth your flatwork needs, placed over ground that drains. Caltrans specifies this material as Class 2 aggregate base, so the term is a specification, not a brand or a grade.

Drainage matters just as much. Rain arrives in a few winter storms and atmospheric rivers, and it sheets off hardscape and dry clay fast. A drainage layer or a drain run moves that water away from the base instead of letting it sit.

The working season is generous. Warm, dry weather suits base and paver work for most of the year, and winter storm days are the main interruption.

Materials for Sunland Projects

Patio and flatwork work starts below the surface. The bedding and base layers carry the load, and the surface material is mostly about how the finished space looks and drains.

Class 2 Base is the material most Sunland patios and driveways are built on. Contractors here also ask for it as Class II base rock or Class 2 aggregate base. It compacts hard and forms the structural layer under pavers, slabs and Stone Screenings paths.

Recycled base rock and crushed miscellaneous base, often shortened to CMB, are the same Class 2 idea made from Road Base or asphalt. Caltrans allows processed reclaimed asphalt and concrete in aggregate base, so they work the same way under a drive or patio.

Stone Screenings, or DG, is the fine path and patio surface that packs firm over a compacted base. It suits low-water landscape ground cover and reads as a finished surface rather than a structural layer.

Mason Sand beds brick and block and fills paver joints. Washed Sand, also called concrete sand, levels and beds under slabs. Both are fine, clean materials that sit directly under hardscape.

For drainage around the same work, Drain Rock and 3/4" Drain Rock are clean stone with no fines, so water moves through instead of pooling. Riprap, specified locally as rock slope protection, armors slopes and culvert outlets against winter runoff.

Pick a delivery date at checkout, and a dump truck brings the material to your site. Bulk loads are usually dropped where the truck can reach, so it helps to know which end of the project the material should land on.
