Cobble and Bulk Aggregates for Glenhaven, CA

California Rock Supply handles gravel and aggregate delivery in Glenhaven, CA. The base material most jobs here start with is Class 2 base, also called Class II base rock. It goes under driveways, parking pads and the compacted layer beneath pavers and slabs. Clay soils are common in the Coast Range valleys and hills, and they swell when wet, so a properly built base matters.

Materials for Glenhaven Projects

Hillside runoff and winter storms drive most of the material decisions in Glenhaven. Coarse stone is how you protect slopes, swales and creek banks from that water. The list below runs from the biggest rock down to the finest fines.

RipRap, also called rock slope protection, is heavy placed rock for slope armoring, creek banks and culvert outlets. Caltrans calls placed rock on slopes rock slope protection. It is the first line of defense where winter runoff hits bare ground.

#4 Crushed Stone and Railroad Ballast are the next sizes down. Both work for trench bottoms, heavy drainage and hard standing where water needs to move fast.

3/4" Drain Rock, also called #57 stone, and Drain Rock are clean washed stone with no fines. Water passes straight through. Use them in French drains, drywells, downspout runs and behind retaining walls.

Below the drainage stone sits the base. Class 2 Base is the standard California base material, and recycled base rock made from Road Base or asphalt is used the same way. Caltrans allows processed reclaimed asphalt and concrete in aggregate base. Some suppliers here call it crushed miscellaneous base or CMB.

On top of that base, Driveway Gravel resurfaces an existing drive and Stone Screenings gives paths and patios a fine, firm-packing surface. Large River Rock works dry creek beds and swales where you want runoff slowed rather than piped away.

Delivery to Glenhaven and the Surrounding Area

You order online and pick your quantity by the ton or the yard. If you are unsure how much a job needs, the calculator sizes the load for you. Then you choose a delivery date at checkout.

A dump truck brings the material to your site and places it where you direct. Glenhaven sits in Lake County, and delivery covers the surrounding area, including Clearlake, Hidden Valley Lake, Lakeport, Kelseyville and Lucerne.

Have the drop spot clear before the truck arrives. Rock is heavy, and a firm, level area keeps the load where you want it.

Ground and Conditions in Glenhaven

The dry season from late spring into fall is the main window for base, driveway and paver work. Winter rain and saturated clay are what hold jobs up. Most rain falls from late fall to spring, often in a few large storms.

That pattern shapes how you build. Sandy ground soaks water in quickly, while clay soils shed it and turn soft. On clay, a compacted Class 2 base keeps the surface above the wet layer, and a drain rock layer gives the water somewhere to go.

On slopes, the same winter storms cause runoff and slides. RipRap and cobble armor those banks. If a slope was recently burned, plan for heavier protection before the rain returns.
