Crushed Stone, Sand and Gravel in Highland, CA

California Rock Supply stocks gravel and aggregate delivery in Highland, CA, from Class 2 base to garden soil. The Inland Empire ground here runs from sandy loam to heavy clay, so the material under a drive or a planting bed matters as much as what sits on top.

Order online by the ton or yard, size the load with the calculator, and a dump truck brings it to your site in San Bernardino County.

Materials for Highland Projects

Soil and fill do the quiet work on most jobs here. Top Soil builds up lawn and bed areas over clay or hardpan, and Garden Soil fills raised beds where roots need loose, workable ground. Fill Dirt raises grade and backfills pads before any base goes down.

Base comes next. Class 2 base, also called Class II base rock, is the standard California base for driveways, parking pads and the compacted layer under pavers and slabs. Class 2 Base is what most local crews ask for by that name. Crusher Run suits drives where you want a binding, compacting material.

Washed stone handles water. 3/4" Drain Rock is clean stone with no fines for French drains and drainage trenches, and Drain Rock covers drywells, downspout runs and the back of retaining walls. RipRap, also called rock slope protection, armors slopes and creek banks against winter storm runoff.

Sand and decorative round out a load. Mason Sand sets brick and block and fills paver joints, while Washed Sand levels and beds under slabs. Stone Screenings, or DG, packs firm for paths and patios. River Cobble and Natural Pea Gravel finish beds and walkways.

Ground and Conditions in Highland

Rain here arrives in a few winter storms and atmospheric rivers after a long dry season. That water runs off hardscape, baked ground and clay fast, so it needs somewhere to go before it pools against a foundation or under a slab.

Much of the ground is expansive clay that swells when wet and shrinks and cracks when dry. Wetting that clay under paving makes it move, which is why a compacted Class 2 base matters more here than in a sandier market.

Where runoff concentrates, order clean washed stone so water passes through instead of sitting. Drain rock and 3/4" drain rock both work with no fines to clog. On slopes and creek banks, rip rap holds the soil when the first heavy storms hit.

The warm, dry season suits base and paver work for most of the year, with winter storm days the main interruption. Schedule grading and compaction around those storms, and plan drainage before the first one arrives.
