Open the calculatorWhat do you order when winter water has nowhere to go? For gravel and aggregate delivery in Santa Margarita, CA, the answer usually starts with washed stone. California Rock Supply stocks 3/4" Drain Rock, Drain Rock and Class 2 Base in bulk, delivered by the ton.
Class 2 base handles the load-bearing work under drives and pads. Washed stone moves the water. That pairing covers most jobs in the Santa Margarita area.
Drainage drives this market. Soils here change over short distances, so sandy ground soaks water fast while clay holds it. Either way, water needs a path out, and clean washed stone is how you build one.
Drain Rock is the workhorse. Use it in French drains, drywells, downspout runs, and behind retaining walls. It carries no fines, so water passes through instead of pooling.
3/4" Drain Rock, also sold as #57 stone, does the same job in drainage trenches and drainage layers under a slab or patio. The uniform size keeps voids open.
For tighter work, 3/8" Crushed Stone handles fine drainage and pipe bedding. #89 Crushed Stone fits the smallest joints and tight bedding.
Then comes the base. Class 2 Base, also called Class II base rock or Class 2 aggregate base, is the standard California base material, specified by Caltrans as Class 2 aggregate base. It goes under driveways, parking pads, pavers, slabs and Stone Screenings paths.
Recycled base rock, made from Road Base or asphalt, works the same way. Caltrans allows processed reclaimed asphalt and concrete in aggregate base, so it is a practical choice under a patio or drive.
Most rain falls from late fall to spring, much of it in a few large winter storms and atmospheric rivers. Sandy ground takes it in quickly. Clay soils and slopes shed it.
That shapes the schedule. 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, so plan your delivery before the ground turns.
On clay, dig the drainage trench deep enough and line it with clean stone so water has somewhere to go. On a slope, arm the outlet with RipRap so winter runoff does not cut the channel wider each season.
Build the base in lifts and compact it. A base that goes down wet or in one thick pass will not hold up under a drive.

Common questions about gravel and aggregate delivery in Santa Margarita, CA
Yes. California Rock Supply delivers Class 2 base, also called Class II base rock, to Santa Margarita and the rest of San Luis Obispo County. Order it online by the ton or the yard for driveways, parking pads and the compacted base under pavers and slabs. You can also add washed drainage stone to the same order so the base and the drainage go in together.
Start with Class 2 base, compacted in lifts, because it is the standard California base material for drives and pads. Then top it with driveway gravel for the wearing surface. If water stands on the drive, put clean drain rock in a trench along the edge first, since clay soils hold water and sandy ground drains fast.
We would rather move a delivery than tear up your ground. If the site is too wet for the truck on the day, we will call you and rebook. Tell us in advance about any part of the approach that does not drain and we will plan around it.
