The ground here decides most of your material list. Alluvial soils range from sandy loam to clay, and expansive clay swells when wet and cracks when dry.

Materials for San Diego Projects

Most San Diego work starts below the surface. You build grade up with fill, cap it with base, then finish with soil or stone. Here is how the main materials sort out.

Soil, Fill and Mulch

Fill dirt, also called structural fill, raises grade and backfills pads before anything else goes down. Topsoil and garden soil handle lawn and bed prep. Both build up planting areas over clay, hardpan or sandy native soil, which is common across the coastal plains and inland valleys. Top Soil, Garden Soil and Shredded Mulch cover beds, raised planters and tree rings.

Base and Driveway Material

Class 2 base is the standard California base, specified by Caltrans as Class 2 aggregate base. It goes under driveways, parking pads, pavers, slabs and Stone Screenings paths. Recycled base rock and crushed miscellaneous base do the same job using Road Base or asphalt, and Caltrans allows processed reclaimed material in aggregate base. Class 2 Base and Crusher Run both compact and bind.

Washed Stone, Sand and Decorative Rock

Drain rock is clean stone with no fines, so water moves through it. Use it in French drains, drywells and behind retaining walls. Stone Screenings, or DG, packs firm for paths and patios. River rock and Natural Pea Gravel finish beds and borders, while mason sand and washed sand handle brick work, paver joints and bedding under slabs.

Ground and Conditions in San Diego

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. Wetting expansive clay makes it swell under slabs and paving, which is why compaction and drainage matter more here than base thickness alone.

Send roof and surface water somewhere useful. A clean drain rock layer moves it away from footings and slab edges instead of letting it sit. Rip rap, also called rock slope protection, armors slopes, creek banks and culvert outlets against winter runoff. On burned hillsides and in canyons, the first heavy storms can push debris flows, and bluff edges along the shoreline take wave erosion.

Frost is not a factor in base depth here. The warm dry season suits base and paver work most of the year, and winter storm days are the main break in the schedule.
