River Rock and Bulk Aggregates for Glendora, CA

If you need gravel and aggregate delivery in Glendora, CA, California Rock Supply sells bulk material by the ton and delivers it to your site. Glendora sits on alluvial ground with pockets of expansive clay that swells when wet and shrinks when dry. That clay is why base depth and drainage matter here before anything gets paved.

Class 2 base is the standard California base material, and it is the one most local jobs start with.

Materials for Glendora Projects

Winter rain arrives in a few heavy storms, and water moves fast off hard dry ground and clay. Drainage stone is what keeps that water away from your base, your footings and your slab edges. Here is what we stock, ordered from the coarsest material down to the finest.

Coarse washed stone

RipRap, also called rock slope protection, armors slopes, creek banks and culvert outlets against storm runoff. Railroad Ballast handles hard standing and severe drainage where you need heavy coarse stone. #4 Crushed Stone works for trench bottoms and construction entrances.

Drainage stone for French drains and drywells

3/4" Drain Rock, also called #57 stone, is clean stone with no fines, so water passes straight through it. Use it in French drains, drainage trenches and drainage layers. Drain Rock covers drywells, downspout runs and the drainage behind a retaining wall.

#67 Stone is a slightly smaller washed size for drainage and concrete work. 3/8" Crushed Stone suits fine drainage, pipe bedding and topping over a compacted base, and #89 Crushed Stone fits tight bedding and joints.

Base and surfacing

Class 2 Base, also called Class II base rock, is specified by Caltrans as Class 2 aggregate base. It goes under driveways, parking pads, pavers, slabs and Stone Screenings paths. Recycled base rock made from Road Base or asphalt does the same job, and Caltrans allows processed reclaimed asphalt and concrete in aggregate base.

For a drive surface, Driveway Gravel tops a compacted base or refreshes an existing one. Crusher Run is the choice when you want a binding, compacting material.

Fines, sand and soil

Stone Screenings, or DG, is a fine, firm-packing surface for paths and patios, laid over a compacted base. Natural Pea Gravel covers play areas, walkways and bedding. Mason Sand serves brick and block work and paver joints, while Washed Sand levels and beds slabs.

Top Soil builds up lawns and beds over clay or hardpan, Garden Soil fills raised beds, and Fill Dirt raises grade before a Class 2 base goes down.

Ground and Conditions in Glendora

The long, warm, dry season here suits base and paver work for most of the year. Winter storm days are the main interruption, so timing a delivery around the forecast saves you a rework. Material that sits through a storm on unprepared ground is harder to compact later.

Expansive clay is the other thing to plan for. Wetting makes it swell under slabs and paving, so excavate to stable material and build your base in lifts. Class 2 base over a properly compacted subgrade is how local crews handle it. Where runoff collects, add a drainage layer of clean washed stone so water has somewhere to go.
