Bulk Material Delivery in Sylmar, CA

For gravel and aggregate delivery in Sylmar, CA, California Rock Supply stocks the base material local crews ask for by name: Class 2 base. It goes under driveways, parking pads and the compacted layer beneath pavers, slabs and Stone Screenings paths. Caltrans specifies it as Class 2 aggregate base, and it is the standard structural layer across Los Angeles County.

Sylmar sits on alluvial ground that runs from sandy loam to clay, so the base you place and the drainage stone around it matter more than the surface color. Order by the ton or yard and we deliver to your site.

Materials for Sylmar Projects

Slope, swale and bank protection is the work that separates a Sylmar project from a flat-lot job. Winter storms drop a season of rain in a few events, and water leaves hard ground and clay fast. Coarse, clean stone is what slows it, spreads it and keeps it from cutting.

Start at the coarse end. RipRap, also called rock slope protection, armors slopes, creek banks and culvert outlets. Caltrans calls placed rock on slopes rock slope protection. #4 Crushed Stone handles heavy drainage, construction entrances and trench bottoms.

Mid sizes do the everyday drainage work. 3/4" Drain Rock, sold elsewhere as #57 stone, is clean stone with no fines, so water moves through it in French drains and drainage trenches. Drain Rock covers drywells, downspout runs and the drainage layer behind retaining walls. Railroad Ballast is the heavy option for hard standing and severe drainage.

Finer sizes finish and bed. 3/8" Crushed Stone works for fine drainage and pipe bedding over a compacted base. Stone Screenings, or DG, packs firm for paths and patios.

Ground and Conditions in Sylmar

The long, warm, dry season suits base and paver work for most of the year. Winter storm days are the main interruption, so timing a delivery around them keeps a project moving.

The ground here is alluvial, running from sandy loam to clay, with expansive clay in many basins and hills. That clay swells when wet and shrinks and cracks when dry, which lifts slabs and paving. The practical answer is a compacted Class 2 base and a drainage layer that moves water away.

Rain arrives in a few winter storms and atmospheric rivers after a long dry season. It runs off hardscape, hard dry ground and clay fast. That runoff is why coarse stone on slopes, swales and banks earns its place here.
