Bulk Gravel Delivery to San Marino, CA

If you are laying a patio, pouring a slab, or rebuilding a driveway, gravel and aggregate delivery in San Marino, CA starts with the bedding under the flatwork. California Rock Supply stocks Class 2 base, the standard California base material, along with the crushed rock, drain rock, sand, and soil that go with it.

The ground here makes that base layer matter. Soils across Los Angeles County run from sandy loam to clay, and expansive clay swells when it gets wet and cracks when it dries out. A thin, poorly compacted base will not hold a paver patio level through that movement.

Ground and Conditions in San Marino

The first sign of a weak base is a patio that rocks underfoot or a driveway that ruts in the wheel paths. That happens when the base was laid too thin or not compacted in lifts, so the pavers move with the clay beneath them.

The fix is a thicker, well-compacted base on ground that drains. Rain here arrives in a few winter storms and atmospheric rivers after a long dry season, and it sheets off hardscape and dry clay fast. Wetting expansive clay makes it swell under slabs and paving, so you want water moving away from the base, not sitting in it.

Washout and slope failures on hillsides are a winter storm problem in this county, so plan drainage runs and slope armoring before the rain starts. The long warm dry season suits base and paver work for most of the year, and winter storm days are the main interruption.

Materials for San Marino Projects

Bedding under pavers and flatwork is where most San Marino jobs start. Class 2 Base, also called Class II base rock or Class 2 aggregate base, is the material Caltrans specifies as Class 2 aggregate base. It compacts hard and holds grade under pavers, slabs, and Stone Screenings paths. Recycled Class 2 base made from Road Base or asphalt does the same job, and some suppliers sell the same material as crushed miscellaneous base.

Over that base, Stone Screenings gives you a fine, firm-packing surface for patios and garden paths. Washed Sand, also called concrete sand, is what you level and bed pavers and slab forms on. Mason Sand handles brick and block work and paver joints.

For drainage, Drain Rock and 3/4" Drain Rock are clean stone with no fines, so water moves through instead of pooling. Riprap, which Caltrans calls rock slope protection, armors slopes and culvert outlets against winter runoff.

For planting areas, Top Soil builds up beds over clay or hardpan, and Shredded Mulch holds moisture through the dry season.
