Materials for Imperial Beach Projects

Class 2 base leads every driveway job here. It is the standard California base material, specified by Caltrans as Class 2 aggregate base, and it compacts into a firm pad under drives, parking areas and pavers. Contractors also call it Class II base, Class 2 aggregate base or base rock.

Top a compacted base with driveway gravel for the finished surface, or with walkway gravel where foot traffic needs a finer, walkable stone. Both lock together and shed water instead of holding it.

Base, Stone and Sand

• Class 2 Base for driveways, parking pads and the compacted base under pavers and slabs.
• Crusher Run for drives and pads where a binding, compacting material is wanted.
• Driveway Gravel to surface an existing drive or top a compacted base.
• Walkway Gravel for paths and garden walkways.
• Stone Screenings, or DG, for paths, patios and low-water ground cover over a compacted base.

Recycled base rock is Class 2 base made from Road Base or asphalt, and it does the same job under drives, patios and slabs. Some suppliers list crushed miscellaneous base, or CMB, alongside it. Caltrans allows processed reclaimed asphalt and concrete in aggregate base.

Washed stone handles water. 3/4" Drain Rock, also sold as #57 stone, goes in French drains and drainage trenches because it carries no fines. Drain Rock works in drywells, downspout runs and behind retaining walls. For slope and culvert armoring against winter runoff, RipRap is placed rock, which Caltrans calls rock slope protection.

Sand and soil round out most orders. Mason Sand sets brick, block and paver joints. Washed Sand, or concrete sand, beds and levels under slabs. Top Soil rebuilds lawn and bed areas over clay or sandy native ground.

Ground and Conditions in Imperial Beach

Rain arrives in a few winter storms and atmospheric rivers after a long dry season. It runs off hardscape, hard dry ground and clay fast. That runoff is the driver behind almost every drainage decision on a coastal San Diego County site.

Soils here run sandy loam to clay, and expansive clay in many basins swells when wet and shrinks and cracks when dry. Wetting that clay pushes up under slabs and paving. Compact your base in lifts and get water moving away from the pad before it soaks in.

Where water has nowhere to go, a clean stone layer is the answer. Use 3/4 inch drain rock or drain rock in trenches, drywells and behind walls, and keep fines out so water passes through. Arm slopes, creek banks and culvert outlets with rip rap before the first heavy storm.

Erosion shows up two ways here: debris flows when the first heavy storms hit burned hillsides and canyons, and wave erosion of bluffs along the shoreline. Both reward stone placed early.

The long, warm, dry season suits base and paver work for most of the year. Winter storm days are the main interruption.
