Bulk Material Delivery in Castaic, CA

Winter storms drop a season of rain in a few days, and water moves fast off hard dry ground and clay. That runoff is why gravel and aggregate delivery in Castaic, CA leans on coarse stone. California Rock Supply stocks the drainage and slope material this ground demands, plus Class 2 base for everything that gets built on top of it.

Materials for Castaic Projects

Start coarse. The biggest stone handles the water, and each smaller size does a tighter job below it.

Coarse stone for slopes, swales and banks

Rip rap is the heavy answer for slope, creek bank and culvert outlet armoring. Placed rock on slopes is how Caltrans specifies rock slope protection, and it holds where fast runoff would otherwise cut a channel. Large river rock slows runoff in dry creek beds and swales, and its rounded shape sits well in decorative and erosion work.

Drainage stone

Below the armor, clean washed stone moves water. Use 3/4" Drain Rock for French drains, drainage trenches and drainage layers, since it carries no fines and water passes straight through. Drain Rock covers drywells, downspout runs and the drainage behind retaining walls. #4 Crushed Stone suits heavy drainage, trench bottoms and construction entrances.

Base and surface material

Class 2 base is the standard California base material, and Caltrans specifies it as Class 2 aggregate base. It goes under driveways, parking pads, pavers and slabs. Recycled base rock, made from Road Base or asphalt, does the same work, and Caltrans allows processed reclaimed asphalt and concrete in aggregate base. Top a compacted base with driveway gravel, or use Stone Screenings for paths and patios.

Ground and Conditions in Castaic

The warm, dry season runs long here, so base and paver work fits most of the year. Winter storm days are the main interruption. Time a delivery around that window and you avoid a load sitting in the rain.

Soils across the Los Angeles County valleys run from Top Soil to clay, with expansive clay in many basins and hills. That clay swells when wet and shrinks and cracks when dry, which moves slabs and paving above it. Build up the grade with fill dirt first, then compact Class 2 base over it.

Rain arrives in a few winter storms and atmospheric rivers after a long dry season. It runs off hardscape and hard dry ground fast, and the first heavy storms can send debris flows off burned hillsides and canyons. Arm slopes and channel runoff before that weather, not after.
