Fill Dirt Delivery for Alamo, CA

California Rock Supply handles gravel and aggregate delivery in Alamo, CA. The base material most Alamo jobs start with is Class 2 base, also called Class II base rock, the standard California aggregate base for driveways, parking pads and the compacted layer under pavers and slabs. In this part of the Bay Area, heavy clay soils crack when dry and swell when wet, so the base under a pad carries real weight.

Most work here happens in the dry season, from late spring into fall. That is the window when grade gets raised and pads get built.

Delivery to Alamo and the Surrounding Area

You order online and pick your quantity by the ton or the yard. If you are unsure how much a job needs, the calculator sizes the load for you. Choose a delivery date at checkout and a dump truck brings the material to your site.

Bulk loads go to driveways, pads and back yards across Alamo and the rest of Contra Costa County. We also deliver to Concord, Richmond, Antioch, San Ramon and Pittsburg. Place the material where the truck can reach it, and the driver drops it as close to the work as the site allows.

Materials for Alamo Projects

Fill and sub-base come first on most Alamo jobs. That means raising grade and building pads before anything visible goes down. Clay ground needs a pad built up in lifts, and Fill Dirt is what brings a low corner or a sloping yard up to level.

Once grade is set, Class 2 Base goes on top and gets compacted. Contractors here specify it as Class 2 aggregate base, and it is the layer that carries a driveway or a slab. Some suppliers also call recycled material CMB, or crushed miscellaneous base, and recycled Class 2 base is made from Road Base or asphalt for the same job.

From there, the material follows the project:

• Driveways: Driveway Gravel surfaced over a compacted base, or Crusher Run where you want a binding, compacting layer.
• Paths and patios: Stone Screenings, or DG, packs firm and fine over a prepared base.
• Drainage: Drain Rock for French drains, drywells and downspout runs, and 3/4" Drain Rock for drainage trenches and layers.
• Slopes and creek banks: RipRap, also called rock slope protection, armors ground against winter storm runoff.
• Beds and planting: Top Soil builds up planting areas over clay, and Shredded Mulch holds moisture through the dry season.

Ground and Conditions in Alamo

Start with the soil, because it decides what a base needs. The Coast Range valleys and hills carry heavy clay that cracks when dry and swells when wet. An under-built base on that ground moves, and the driveway or pavers above it move with it.

Water is the other half. Most rain falls from late fall to spring, much of it in a few large winter storms and atmospheric rivers. That water soaks into sandy ground quickly but sits on or runs off clay soils and slopes.

So a pad gets built up and compacted in lifts, not dumped in one pass. Drainage goes in on the wet side of a retaining wall or a slope. Timing matters too: base, driveway and paver work belongs in the dry season, and saturated clay is what holds a job up.
