Gravel and Aggregate Delivery in San Carlos, CA

Plan your gravel and aggregate delivery in San Carlos, CA around the dry season. Late spring into fall is the window when base, driveway and paver work moves fastest. Winter rain is what stops a job here, not cold. California Rock Supply stocks Class 2 base, the standard California base material, and delivers it across San Mateo County.

Timing matters because the ground tells you when it is ready. Heavy clay soils in the Coast Range valleys and hills swell when wet and crack when dry. Base work waits for dry ground.

Materials for San Carlos Projects

Most drives here start with base, not surface stone. Class 2 base, also called Class II base or Class 2 aggregate base, is specified by Caltrans as Class 2 aggregate base. It goes under driveways, parking pads and the compacted layer beneath pavers, slabs and Stone Screenings paths. You can order it as Class 2 Base.

Recycled base rock is Class 2 base made from Road Base or asphalt, used the same way. Caltrans allows processed reclaimed asphalt and concrete in aggregate base. Some suppliers also call this crushed miscellaneous base, or CMB. If a compactor is what you want, Crusher Run binds and packs, though California buyers more often ask for Class 2 base for the same job.

Once the base is compacted, the surface layer is a separate choice. Walkway Gravel suits garden paths that need a finer, walkable surface. Stone Screenings, or DG, packs firm for paths, patios and low-water ground cover. For water that has to move, 3/4" Drain Rock is clean washed stone, so it drains instead of holding moisture.

Ground and Conditions in San Carlos

Most rain here falls from late fall to spring, often 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. The result is simple: a driveway built on clay without a drainage layer holds water and loses its compaction.

Soils change over short distances in this zone. Sandy dune and beach soils sit along parts of the shoreline, while heavy clay soils that crack when dry and swell when wet are extensive in the Coast Range valleys and hills. On a clay site, plan a deeper base and a clean stone drainage layer, and compact in lifts.

Hillside runoff and slides on steep slopes are the winter risk, along with wave and storm erosion of sea cliffs and bluffs along the shoreline. Rip rap, also called rock slope protection, armors slopes, creek banks and culvert outlets against storm runoff. Frost is not a factor in base depth here.

Delivery to San Carlos and the Surrounding Area

Bulk material arrives by dump truck and is placed where the truck can reach. Have the drop zone cleared and marked before it shows up. Ten feet of clear width is enough for most loads, and a level spot keeps the pile from sliding.

Order online and size the load by the ton or the cubic yard. Base is usually figured by the ton, decorative stone and soil often by the yard. Multiply length by width by depth in feet, then divide by 27 for cubic yards. A minimum depth of 2 inches holds for decorative topping, while base runs deeper.

California Rock Supply delivers across San Mateo County, including San Mateo, Daly City, Redwood City, South San Francisco and San Bruno. San Carlos sits in San Mateo County, so coverage reaches the whole city.
