Bulk Material Delivery in Cotati, CA

Winter rain is the whole story here. Storms roll in from late fall to spring, and clay ground in the Sonoma County valleys holds that water instead of taking it. That is why gravel and aggregate delivery in Cotati, CA leans on clean washed stone. California Rock Supply stocks the drainage materials that move water away from a house, a drive, or a retaining wall before it becomes a problem.

Class 2 base, also called Class II base rock, handles the load-bearing work, specified by Caltrans as Class 2 aggregate base. The washed stone handles the water.

Materials for Cotati Projects

Start coarse and work down. Heavy drainage stone goes in trenches and French drains, where the voids do the work. Smaller washed sizes go around pipe, behind walls, and under downspouts.

For a drywell or a long downspout run, drain rock is the first call. It is washed, so it has no fines to pack tight and seal off the flow. A trench wrapped in filter fabric and filled with this stone gives roof water somewhere to go besides the low corner of the yard.

Where a wall or embankment needs a drainage layer, 3/4" Drain Rock is the standard size. It sits behind the wall, water drops through it, and a perforated pipe at the base carries it off. Pair it with #4 crushed stone at the trench bottom when the ground is soft and the stone needs a stable footing.

Finish tight work with #8 crushed stone. It beds pipe, fills paver joints, and tops small drainage features without the surface moving underfoot.

Under all of it, Class 2 base carries the load. Class 2 aggregate base is the standard California base material, and it compacts firm under drives, patios and slabs.

For the surface, driveway gravel tops a compacted base, and Stone Screenings packs firm on paths and patios. rip rap, also called rock slope protection, armors slopes and culvert outlets.

Ground and Conditions in Cotati

Timing decides the job. 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 a schedule up.

Soils here change over short distances. Sandy ground takes water fast. Heavy clay in the Coast Range valleys cracks when dry and swells when wet, then sits wet long after a storm passes.

That changes two things. First, drainage goes in before the base, not after. A French drain or drywell placed while the trench is open costs far less than tearing out finished work later. Second, clay subgrade needs to be dry and compacted before Class 2 base goes down, or the base pumps and the surface fails.

On slopes, winter storms drive hillside runoff. RipRap at a culvert outlet or along an eroding bank slows that water before it cuts a channel.

Schedule a delivery for the dry window and stage stone where the machine can reach it. Mud season is not the time to discover the truck cannot get to the pad.
