River Rock and Bulk Aggregates for Alturas, CA

If you need gravel and aggregate delivery in Alturas, CA, California Rock Supply sells bulk material online and delivers it to your site. Local ground is mostly thin and rocky, with coarse sandy pockets where granite has weathered. That shallow profile is why Class 2 base has to go down thick enough to bridge soft spots before anything is built on top.

Winter storms and snowmelt keep the ground wet into spring, so drainage matters as much as the base itself.

Materials for Alturas Projects

Water is the thing that ruins drives, pads and retaining walls around here. Snowmelt and storm runoff move fast off rock and thin soil, then collect where a drive or pad cuts across the slope. Washed stone is how you give that water somewhere to go. Everything below is listed coarsest to finest.

RipRap is the biggest option, used as rock slope protection on creek banks, steep slopes and culvert outlets where winter runoff hits hardest. Railroad Ballast is the next step down, a heavy coarse stone for hard standing and severe drainage. #4 Crushed Stone handles heavy drainage, trench bottoms and construction entrances.

For the drainage work most Alturas properties actually need, 3/4" Drain Rock is the standard choice. It is clean stone with no fines, so water moves through it instead of sitting in it. Use it in French drains, drainage trenches and drainage layers. Drain Rock covers the same jobs at other sizes, including drywells, downspout runs and the drainage behind retaining walls.

At the finer end, 3/8" Crushed Stone works for fine drainage, pipe bedding and topping over a compacted base. #89 Crushed Stone is small washed stone for joints and tight bedding.

Once drainage is handled, Class 2 Base is the material that carries the load. It is the standard California base, specified by Caltrans as Class 2 aggregate base, and it goes under driveways, parking pads and the compacted layer beneath pavers, slabs and Stone Screenings paths. Recycled base rock and crushed miscellaneous base do the same job where a recycled material suits the site.

On top, Driveway Gravel surfaces an existing drive or tops a compacted base, and Stone Screenings gives paths and patios a fine, firm-packing finish.

Ground and Conditions in Alturas

The working window here runs late spring to fall. Snow and frozen or saturated ground stop most base and excavation work through winter, and the spring thaw can leave unpaved ground soft for a while after. Time a delivery for that window and the material compacts the way it should.

Freeze-thaw is a real design factor in this part of the mountains, since freezing nights are routine through winter. Frost depth is set by the local building department, so check with them before you plan footings or buried work.

Thin, rocky soil over granite and volcanic rock is another reason to build up rather than cut down. Fill Dirt raises grade and backfills pads before Class 2 base goes down. Where native soil is too coarse or too shallow to hold moisture, Top Soil and Garden Soil build up planting areas instead.
