Bulk Gravel Delivery to Lewiston, CA

Planning gravel and aggregate delivery in Lewiston, CA around the season is the first practical step. The working window runs late spring to fall. Snow and frozen or saturated ground stop most base and excavation work in winter, and the spring thaw leaves unpaved ground soft. California Rock Supply stocks Class 2 base, the standard California base material, for delivery across Trinity County.

Ground and Conditions in Lewiston

Most of the ground here is thin and rocky, with coarse sandy patches where granite has weathered. That matters for a patio, because a thin base fails first. A paver or slab laid over too little compacted base rocks, settles and drops at the corners.

The fix is a properly compacted base, built up and watered in before anything goes on top. Winter storms bring rain and snow, and melting snow keeps the ground wet into spring. Water runs fast off rock and thin soil on slopes and collects where drives and pads cut across it. So drainage under and beside flatwork is not optional here.

Freeze-thaw is a real design factor. Freezing nights are routine through winter at this elevation. Frost depth is set by the local building department, so check with them before you set footings or plan base depth.

Materials for Lewiston Projects

Bedding under pavers and flatwork is where most of the thought goes on a patio job. The layers below the surface decide whether the surface stays flat.

Start with Class 2 Base, also called Class II base or Class 2 aggregate base. Caltrans specifies it as Class 2 aggregate base. It is the compacted layer under pavers, slabs and Stone Screenings paths. Recycled base rock, made from Road Base or asphalt, does the same job; Caltrans allows processed reclaimed asphalt and concrete in aggregate base. Some suppliers call that crushed miscellaneous base, or CMB.

For the surface, Stone Screenings (DG) packs firm and fine, which suits paths and patio ground cover laid over a compacted base. Driveway Gravel surfaces an existing drive or tops a Class 2 base. Walkway Gravel gives paths a finer, walkable finish.

Above the base and below the surface, Washed Sand levels and beds slabs and pavers, and Mason Sand fills paver joints and handles brick and block work. For drainage behind a retaining wall or in a French drain, Drain Rock is clean stone with no fines, so water moves through it. 3/4" Drain Rock does the same job in trenches and drainage layers.

For planting, Top Soil rebuilds lawns and beds over thin rocky ground, and Shredded Mulch holds moisture in beds and tree rings through the long dry season. Where grade needs raising before a base goes down, Fill Dirt builds up the pad first.
