Fill and Base Material Delivered in Altadena, CA

California Rock Supply handles gravel and aggregate delivery in Altadena, CA. The material most projects here start with is Class 2 base, also called Class II base rock, the standard California base for driveways, parking pads and the compacted layer under pavers and slabs. Altadena ground runs from Top Soil to expansive clay that swells when wet and cracks when dry, so what goes under a slab matters.

Delivery to Altadena and the Surrounding Area

You order online and pick your quantity by the ton or the yard. If you are unsure how much a pad or drive needs, use the calculator to size the load before checkout.

Pick your delivery date at checkout and a dump truck brings the material to your site. California Rock Supply delivers across Altadena in Los Angeles County and to nearby places including Los Angeles, Glendale, Santa Clarita, Long Beach and Lancaster.

Bulk loads need a spot the truck can reach and dump. A clear driveway, a wide street frontage or an open lot works best. Plan where you want the pile to land so you are not moving material twice.

Materials for Altadena Projects

Most jobs here start below the surface. Fill dirt raises grade and builds up a pad before anything else goes down. It is also used for backfill and for leveling low spots that hold water. Once the pad is built and compacted, Class 2 base goes on top as the structural layer under driveways, paver patios and slabs.

From there, the material follows the project. Here is how the common ones break down.

For a driveway, build the pad with fill dirt, compact Class 2 base over it, then surface with driveway gravel. For a patio or path, Stone Screenings, also called DG, packs firm and fine over that same base. For drainage, drain rock carries water away from the house and off the slope.

Recycled base rock, also called recycled Class 2 base, is made from Road Base or asphalt and does the same job under drives, patios and slabs. Some suppliers here call it crushed miscellaneous base, or CMB. It is a practical choice when you want a compacted structural layer for a pad.

For planting, topsoil rebuilds lawn and bed areas over clay or sandy native ground. Garden soil fills raised beds, and shredded mulch holds moisture in beds and tree rings through the long dry season.

Ground and Conditions in Altadena

Altadena sits on alluvial fans and terraces with soils that range from Top Soil to clay. The expansive clay in many basins and hills is the part that shapes how you build. It swells when wet and shrinks and cracks when dry.

That movement is why an under-built base fails. A thin base over swelling clay lets the slab or paving shift with the seasons. Build the pad up with fill dirt, compact the Class 2 base in lifts, and keep water from sitting under the edge of the work.

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 grade the site to move water away. Wetting expansive clay makes it swell under slabs and paving.

The long, warm, dry season suits base and paver work for most of the year. Winter storm days are the main interruption, so plan the grading and drainage work around them.
