Order Class 2 Base and Crushed Stone in Los Angeles County, CA
California Rock Supply delivers gravel, stone and aggregate delivery in Los Angeles County, CA. Class 2 base is the material most orders start with, and it is the standard California base under drives, pads and pavers. Soils here run from Top Soil to clay, and the expansive clay in many basins swells when wet and shrinks when dry.

Class 2 base is the higher-strength grade of California aggregate base, specified by Caltrans Standard Specifications Section 26 as Class 2 or Class 3 aggregate base, in a 3/4 inch or 1-1/2 inch maximum grading. Buyers also call it Class II base, Class 2 aggregate base or base rock. It goes under driveways, parking pads and the compacted base beneath pavers, slabs and Stone Screenings paths.
Class 2 base is also sold recycled. Caltrans allows processed reclaimed asphalt and concrete in aggregate base, which is why recycled Class 2 base and crushed miscellaneous base (CMB) are common names for the same job: drive and pad subgrade.
Crushed rock rounds out the list. Use 3/4" Crushed Stone for drainage beds and construction entrances, and 3/8" Crushed Stone for pipe bedding and topping a compacted base. For decorative beds, borders and dry creek beds, order River Cobble or larger Large River Rock where runoff needs slowing.
Ground Conditions Across Los Angeles County
The failure mode in this county is a base that looks fine in July and pumps in January. Expansive clay under the coastal plains and inland valleys swells when wet, so a too-thin base cracks and settles under slabs and paving. The fix is depth and compaction: build up the base in lifts and compact each one before the next goes down.
Rain arrives in a few winter storms and atmospheric rivers after a long dry season. It runs off hardscape, hard dry ground and clay fast, so drainage has to be planned, not added later. Order clean drain rock for trench and wall work, and keep fines out of the drainage layer.
The county spans three ground zones, and they fail differently. Los Angeles, Long Beach, Santa Clarita and Glendale sit on alluvial plains, fans and terraces with expansive clay in many basins. Lancaster, Palmdale, Acton and Littlerock sit on sandy and gravelly desert soils that take water quickly, with flash floods scouring washes and wind moving sand on bare ground.
Timing follows the same split. The long, warm, dry season suits base and paver work for most of the year in the valleys, with winter storm days the main interruption. On the low desert, the cooler months are the best working window.
Delivery Across Los Angeles County
Start with quantity, because that decides the load. Order by the ton when you know the weight you need, such as a base depth over a measured pad. Order by the yard when you are filling a volume, such as topsoil for beds.
We cover Los Angeles, Long Beach, Santa Clarita, Glendale, Lancaster, Palmdale, Pomona, Torrance, Pasadena, Downey, El Monte, West Covina, Inglewood and Burbank. Size the load before you order, and split large jobs into loads that fit your access.
Have the site ready. Clear the drop area, mark any sprinkler lines or utilities, and check that the truck can reach the spot without overhead wires or low branches in the way.
Choosing the Right Material
Neighboring counties show how fast the right answer shifts. Orange County shares this county's coastal plain and inland valley zone, so the ground is similar: alluvial soils with expansive clay, and the same Class 2 base and drainage approach. The difference is typical projects, not material choice.
San Bernardino County spans this county's zone plus deserts and mountains, so a single answer stops working. A High Desert pad needs the same compacted base but more attention to flash-flood scour, while a mountain town adds freeze-thaw to the base design. Kern County spans the Central Valley floor, Sierra foothills, deserts and mountains, so its orders swing from valley base work to slope armoring.
Los Angeles County sits in the middle of that range. Use Class 2 base for structure, drain rock and crushed rock for water, and rip rap where runoff hits a slope. Match the material to the zone you are building in.
Questions About Ordering Aggregate in Los Angeles County
Should I order material by the ton or by the yard?
Order by the ton when the job is weight-driven, such as Class 2 base at a set depth over a measured pad. Order by the yard when you are filling a volume, such as topsoil, garden soil or mulch for beds. If you know the area and the depth, either unit works; convert once and order the number you land on.
Which stone is best for drainage in Los Angeles County?
Clean, washed stone with no fines is what moves water. Use 3/4" Drain Rock or Drain Rock for French drains, drywells and behind retaining walls. For finer work, 3/8" Crushed Stone suits pipe bedding.
What do I need to have ready for a bulk delivery?
Have a clear drop area the truck can reach, with no overhead wires or low branches. Mark sprinkler lines, utilities and anything you do not want driven over. Know where you want the pile placed, because a dump load is dropped, not poured.
