Cobble and Bulk Aggregates for Whittier, CA

California Rock Supply handles gravel and aggregate delivery in Whittier, CA, and Class 2 base is the material most local jobs start with. It is the standard California base, specified by Caltrans as Class 2 aggregate base, and it goes under driveways, parking pads, pavers and slabs. Whittier sits on alluvial ground where soils run from sandy loam to expansive clay, so what you put on top matters less than what drains beneath it.

Materials for Whittier Projects

This is a region of slopes, swales and storm channels, so coarse stone does the heavy work. Rip rap, also called rock slope protection or rsp, armors slopes, creek banks and culvert outlets against winter runoff. A Whittier hillside below a burn scar sends debris fast when the first storms arrive.

Sizes run from coarsest to finest, and each one has a job. Start at the top of the range for slope and bank protection and work down toward the fines you compact.

For clean drainage stone, 3/4 inch drain rock (also sold as #57 stone) has no fines, so water moves straight through it. Use it in french drains and drainage trenches. Recycled base rock works the same way as Class 2 base under drives and patios, and Caltrans allows processed reclaimed asphalt and concrete in aggregate base.

On the fine end, Stone Screenings packs firm for walkways and patios, and Class 2 base is the layer beneath it. For walkable surfaces, walkway gravel and driveway gravel top an existing or newly compacted base.

Ground and Conditions in Whittier

The long, warm, dry season suits base and paver work for most of the year. Winter storm days are the main interruption. If you are timing a delivery, aim for the dry stretch and get the base compacted before rain reaches it.

Clay is the local complication. Many basins and hills around Whittier hold expansive clay that swells when wet and shrinks and cracks when dry. Wetting that clay lifts and cracks slabs and paving above it, so drainage has to move water away from the subgrade, not just off the surface.

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. That is why a drainage layer of clean stone under and beside a slab earns its place, and why slope and bank work goes in before the storms, not after.

Delivery to Whittier and the Surrounding Area

Order online and pick your quantity by the ton or the yard. If you are unsure how much a pad or a bed takes, size the load with the calculator before you check out. Then pick a delivery date at checkout that matches when your crew and equipment are on site.

A dump truck delivers bulk material to the site and places it where you direct. Have the drop zone clear and reachable, with room for the truck to enter, dump and leave. For slope and bank work, think about where the stone lands relative to the work face.

Coverage runs across Whittier and the rest of Los Angeles County, including Los Angeles, Long Beach, Santa Clarita, Glendale and Lancaster.

Questions from Whittier Buyers

What stone should I use for drainage in Whittier?

Use clean, washed stone with no fines. Drain rock and 3/4 inch drain rock (#57 stone) are the standard choices for french drains, drywells and downspout runs, because water passes through the voids. Behind a retaining wall or under a drainage layer, the same clean stone keeps water moving. Avoid base materials with fines in a drainage application; they compact and hold water instead of releasing it.

What should I have ready when the truck arrives?

A clear, reachable drop zone and someone on site to direct the driver. The truck needs room to enter, dump and pull out, so move vehicles, trailers and equipment first. Point out where you want the pile so it lands close to the work and does not block a driveway or street. If the load is going on a slope or a tight side yard, say so before the driver positions.
