Bulk Gravel Delivery to San Bruno, CA

Planning a patio, a driveway, or a drainage run? California Rock Supply handles gravel and aggregate delivery in San Bruno, CA, and most flatwork here starts with Class 2 base. It is the base material Caltrans specifies as Class 2 aggregate base, and local crews call it class ii base or base rock.

San Bruno sits in San Mateo County, where soils swing between sandy ground near the shoreline and heavy clay that swells when wet. That mix decides how a patio pad or drive is built and bedded.

Ground and Conditions in San Bruno

A thin base is where patios and drives fail first. On clay, water sits instead of draining, the pad moves, and pavers rock or settle out of line. That is why a compacted Class 2 base layer matters more than the surface material on top.

Sandy ground near the shoreline takes water fast. Clay in the Coast Range valleys and hills does the opposite, and winter storms deliver most of the rain in a few large events. Erosion shows up on steep slopes and along sea bluffs, where rip rap, also called rock slope protection, armors banks and culvert outlets.

The dry season from late spring into fall is the main window for base, driveway and paver work. Summer fog near the shore is not the problem; saturated clay is, and it holds jobs up until the ground dries.

Materials for San Bruno Projects

Bedding and base under pavers and flatwork is the core of most San Bruno orders. Class 2 base carries the load under a patio, a walkway or a slab, and it compacts firm so the surface above stays flat. Recycled base rock, also called recycled class 2 base, does the same job when made from Road Base or asphalt, and Caltrans allows processed reclaimed material in aggregate base.

Above the base, Stone Screenings, also called DG, packs into a firm path or patio surface with a fine, walkable finish. Washed sand, also called concrete sand, levels and beds pavers and slabs, and mason sand, or masonry sand, fills joints and works for brick and block.

For drives, driveway gravel surfaces an existing drive or tops a compacted Class 2 base. Walkway gravel gives paths a finer, walkable finish. Where water has to move, drain rock and 3/4 inch drain rock (also called #57 stone) are clean stone with no fines, so water passes through instead of pooling.

Crusher run is another option for drives and pads where a binding, compacting material is wanted, though California buyers more often ask for Class 2 base for the same job. Fill dirt, or structural fill, raises grade and backfills before the base goes down.

Yards and beds round out the list. Topsoil, also called screened topsoil, builds up planting areas over clay or hardpan, garden soil fills raised beds, and shredded mulch holds moisture through the long dry season.
