Order Gravel, Stone and Soil in Pomona, CA

Winter storms hit Pomona hard. Rain sheets off hard dry ground and clay, runs fast, and swells the expansive clay under slabs and paving. Gravel and aggregate delivery in Pomona, CA has to answer that. California Rock Supply stocks Class 2 base, the local base rock for drives, pads and the compacted layer under pavers.

Materials for Pomona Projects

Most jobs here start with grade. You build a pad up before anything goes on top. That means fill and sub-base first, then the surface material for the project.

For a driveway, start with Fill Dirt to raise grade and backfill. Compact it, then cap it with Class 2 Base, the Caltrans Class 2 aggregate base California specifies. Top an existing drive with Driveway Gravel instead.

For a patio or paver walk, Class 2 base carries the load. Set pavers on Mason Sand. For a path or low-water ground cover, lay Stone Screenings over that compacted base. DG packs firm underfoot.

For drainage, order clean stone with no fines. Drain Rock handles French drains, drywells, downspout runs and the backfill behind retaining walls. 3/4" Drain Rock works the same way in drainage trenches and beds.

Planting areas need soil, not base. Top Soil rebuilds lawns and beds over clay or hardpan native ground. Garden Soil fills raised beds.

Ground and Conditions in Pomona

Pomona sits on alluvial plains, fans and terraces. Soils run from sandy loam to clay. Much of the ground is expansive clay that swells when wet and shrinks and cracks when dry.

That clay is why an under-built base fails. Skip compaction and the slab moves. Wet the clay and it lifts the paving.

Two things fix it. First, dig out enough and rebuild the grade with fill and Class 2 base at the right depth. Second, move water away. Drain rock in a trench or behind a wall gives runoff somewhere to go before it reaches the clay.

The dry season runs long and warm. Base and paver work goes most of the year. Winter storm days are the main interruption, and that is when the ground soaks and stays soft. In the hills and canyons, the first heavy storms after a burn move debris fast. RipRap armor on slopes and culvert outlets slows that runoff.
