Crushed Stone, Sand and Gravel in Los Osos, CA

Order gravel and aggregate delivery in Los Osos, CA online by the ton or the yard. California Rock Supply drops bulk material at your driveway, pad or garden gate. Start with Class 2 base for anything compacted, then pick your surface and soil.

Soils here change fast. Sandy ground near the shore drains quickly, while clay in the valleys holds water. Choose material for the ground you actually have.

Materials for Los Osos Projects

Soil and grading come first. Build the grade, then cap it. Get the base layers right and every surface above them lasts longer.

Soil, Fill and Mulch

Top Soil builds up lawns and beds over clay or sandy native ground. Garden Soil fills raised beds and planting areas. Use Fill Dirt to raise grade and backfill pads before base goes down. Shredded Mulch holds moisture through the long dry season.

Base

Class 2 Base, also called Class II base or class 2 aggregate base, is the standard California base. Caltrans specifies it as Class 2 aggregate base. It goes under driveways, parking pads, pavers and slabs. Crusher Run works where you want a binding, compacting material.

Washed Stone

Drain Rock and 3/4" Drain Rock have no fines, so water moves through them. Use them in French drains, drywells and behind retaining walls. 3/4" Crushed Stone suits drainage beds and construction entrances.

Sand and Decorative

Mason Sand sets brick, block and paver joints. Washed Sand levels and beds slabs. Stone Screenings, or DG, packs firm for paths and patios. RipRap armors slopes and creek banks.

Ground and Conditions in Los Osos

Most rain lands from late fall to spring, often in a few big winter storms. Sandy ground soaks it up fast. Clay soil and slopes do not. Water sits on clay and runs off hillsides.

That split drives material choice. On clay, dig your base deep enough and compact in lifts so the pad does not pump when saturated. On sand, keep fines out of drainage stone and let clean rock do the work.

Winter brings hillside runoff and slides on steep slopes, plus wave and storm erosion along the bluffs. Armor exposed banks with RipRap and run drainage away from structures. The dry season from late spring into fall is the window for base, driveway and paver work. Summer fog near the shore is fine. Saturated clay is what holds jobs up.
