Cobble and Bulk Aggregates for Mount Hamilton, CA

Need gravel and aggregate delivery in Mount Hamilton, CA? California Rock Supply stocks the washed stone that handles mountain runoff. Start with Class 2 base for the compacted layer under drives and pads. Then add clean drain rock where water needs to move.

Thin, rocky ground over granite sheds water fast. Snowmelt keeps it running into spring. The right stone decides whether that water drains or sits.

Materials for Mount Hamilton Projects

Water is the job here. Winter storms and melting snow run hard off rock and thin soil, then pool where a drive or pad cuts across a slope. French drains, drywells and downspout runs move that water away from the structure. Clean washed stone is what makes them work.

Start coarse and work down. Larger washed stone carries the most flow and resists clogging at the bottom of a trench.

Set the drainage first, then build over it. Class 2 base, also called Class II base rock, is the standard California base material, specified by Caltrans as Class 2 aggregate base. It goes under driveways, parking pads and the compacted base beneath pavers and slabs. Some suppliers also call it crushed miscellaneous base, or CMB. Order it as Class 2 Base.

Recycled base rock works the same way. Caltrans allows processed reclaimed asphalt and concrete in aggregate base. It suits drives, patios and slab subgrade where you want to keep material out of the landfill.

Top the base with Driveway Gravel for a working surface. For paths, use Walkway Gravel or a fine, firm-packing material like Stone Screenings. Around beds, borders and dry creek beds, River Cobble and Large River Rock slow runoff and hold soil in place.

Ground and Conditions in Mount Hamilton

Time the work to the season. The working window is late spring to fall. Snow and frozen or saturated ground stop most base and excavation work in winter at the higher towns, and the spring thaw can leave unpaved ground soft.

Freeze-thaw is a real design factor here. Freezing nights are routine through winter, with snow heavy and lasting at the highest towns and lighter or short-lived lower down. The local building department sets frost depth, 18 to 24 inches in mountain towns such as Big Bear Lake, Truckee and Mammoth Lakes.

Plan a delivery once the ground firms up and the forecast holds. Dumping base or fill on soft, saturated ground ruts it and mixes the material. On slopes, storm runoff and snowmelt cut into unpaved roads and bare ground fast, so build the drainage layer before the surface goes down.
