Bulk Material Delivery in San Lorenzo, CA

Winter storms drive the work here. Rain hits the hills, runs hard, and takes soil with it. Gravel and aggregate delivery in San Lorenzo, CA starts with that problem, and with stone that holds ground in place.

California Rock Supply stocks Class 2 base for drives and pads, plus the coarse rock that armors slopes, swales and creek banks. Order online and a dump truck brings it to your site.

Materials for San Lorenzo Projects

Erosion work runs on stone size. Big, angular rock locks together and stays put when water moves. Smaller washed stone lets water pass. Pick the size that matches the job, then build up or finish with base and fines.

Start coarse. RipRap, also called rock slope protection, is heavy placed rock for slope faces, creek banks and culvert outlets. It takes the punch of winter runoff so soil stays where it is.

Next down, #4 Crushed Stone and Railroad Ballast handle trench bottoms, hard standing and severe drainage where water moves fast and often.

For clean drainage with no fines, use 3/4" Drain Rock in French drains, drainage trenches and behind retaining walls. Water passes through and the surrounding soil stays drained.

Then the base layer. Class 2 Base, also called Class II base rock or Class 2 aggregate base, is the standard California base under driveways, parking pads, pavers and slabs. Caltrans specifies it as Class 2 aggregate base. Recycled base rock from Road Base or asphalt does the same job.

Finish with fines. Stone Screenings, or DG, packs firm for paths and patios. Driveway Gravel tops an existing drive or a compacted base.

Ground and Conditions in San Lorenzo

Time the work around the rain. The dry season from late spring into fall is the main window for base, driveway and paver work. Winter rain and saturated clay are what hold jobs up.

Soils here change over short distances. Sandy ground near the shoreline soaks water in fast. Heavy clay in the Coast Range valleys and hills cracks when dry and swells when wet, so it sits wet and sheds runoff instead of absorbing it.

That clay decides how you build. Compacted Class 2 base over wet clay needs drainage beside it, not just under it. Run a drain rock trench along the low edge, and water has somewhere to go.

Slopes need the coarse end of the list. Hillside runoff and slides in winter storms, plus debris flows when intense rain hits recently burned slopes, are what rip rap and cobble are placed for. Order the stone before the first big storm, not after.
