Cobble, Stone and Soil Delivery in Upland, CA

What do you order for gravel and aggregate delivery in Upland, CA? It depends on whether you are building a drive, moving water, or planting. California Rock Supply delivers bulk Class 2 base, washed stone, sand and soil by the ton across San Bernardino County.

Upland sits on alluvial ground that drains fast in the sun and swells when winter rain soaks the clay. Get the stone size right and your job handles both.

Materials for Upland Projects

Drainage is the first order of business on most Upland jobs. Water comes off roofs, patios and hard ground fast in a storm, so you need clean washed stone with no fines, where water passes straight through instead of pooling.

For French drains, drywells and downspout runs, order Drain Rock or 3/4" Drain Rock. Both are washed, so they stay open and move water away from the house and the slab edge.

Material size runs from coarse to fine. Coarse stone takes heavy flow, mid sizes handle drainage beds and fine stone beds pipes and joints.

Under everything, Class 2 Base, also called Class II base rock, is the standard California base, specified by Caltrans as Class 2 aggregate base. Recycled Class 2 base from Road Base or asphalt does the same job under drives and slabs, and Caltrans allows processed reclaimed material in aggregate base.

Ground and Conditions in Upland

The working season here is long. Warm, dry weather suits base, paver and drainage work for most of the year, and winter storm days are the main interruption. Time a delivery around those storms rather than into them.

That matters because the ground changes with the weather. Soils across the Inland Empire valleys run from sandy loam to clay, and the expansive clay in many basins swells when wet and shrinks and cracks when dry. Wetting it under a slab or a drive makes it move.

Two habits prevent that. Compact the Class 2 base in lifts so it locks up before paving, and put a clean drainage layer where runoff collects. Run downspouts into a drywell or a stone-filled trench instead of against the foundation.

On slopes and creek banks, arm the edges with RipRap before the first heavy storm. Burned hillsides and canyons above the valley shed debris flows when the rain finally arrives.
