Duarte sits on alluvial ground that runs from Top Soil to clay, and the clay swells when winter rain soaks it. That ground moves under a patio slab or a paver field. The right base holds it still.

Ground and Conditions in Duarte

A thin base fails first at the edges. The pavers rock, joints open, and the slab corners crack. Expansive clay is the cause. It swells when wet and shrinks and cracks when dry, so the bedding and base have to spread that movement across a firm, uniform layer.

Water drives the problem. 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. Without a drainage layer, that water sits in the base and the clay under it swells.

Build for the dry season and plan around the wet one. Warm, dry weather suits base and paver work for most of the year. Winter storm days are the main interruption. Hillside runoff and slope failures show up in those storms, so route water away from the patio edge before you place stone.

Materials for Duarte Projects

Patios and flatwork live on their bedding. Under pavers, you want a compacted Class 2 base, then a thin leveling course of washed sand or gravel sand. Class 2 base, also called Class II base or Class 2 aggregate base, is the standard California base material, specified by Caltrans as Class 2 aggregate base. It compacts hard and stays put under a slab.

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

For a drive or a pad that needs a binding surface, crusher run compacts into a tight mat. California buyers more often ask for Class 2 base for the same job.

Set the finish on top. Use driveway gravel over a compacted base, walkway gravel on garden paths, or Stone Screenings (DG) for paths and patios that pack firm.

Move water before it reaches the clay. 3/4" Drain Rock has no fines, so water passes through it in French drains and drainage layers. Drain Rock handles drywells, downspout runs and the back of retaining walls.

Finish the yard with river cobble in decorative beds and borders, large river rock in dry creek beds and swales, or Natural Pea Gravel on play areas and walkways.

Bed the hardscape in mason sand for brick, block and paver joints. Prep planting areas with top soil over clay or hardpan, garden soil in raised beds, and shredded mulch to hold moisture through the dry season. Raise grade first with fill dirt before the base goes down.
