Cobble, Stone and Soil Delivery in Covina, CA

Winter storms hit hard here. Rain sheets off hard dry ground and clay, and it finds every low spot and slope. California Rock Supply delivers gravel and aggregate delivery in Covina, CA, with the coarse stone that slows that water down. Start with Class 2 base for anything structural, then size up to rip rap and cobble where runoff needs controlling.

Materials for Covina Projects

Slope, swale and bank protection starts with coarse stone. Water moves fast off hard ground and clay, so the stone you place has to be heavy enough to stay put and open enough to let flow through. Order by size, coarsest to finest, and match the stone to the job.

Rip rap, also called rock slope protection, is the heavy end of the range. Caltrans specifies placed rock on slopes as rock slope protection, and it is what holds a bank when the first big storm arrives. Use it at culvert outlets and anywhere concentrated flow cuts into soil.

Large river rock and cobble slow runoff in dry creek beds and swales. Rounded stone spreads flow instead of deflecting it, so it works well in a decorative bed that also has to move water. Pair it with River Cobble for the smaller beds and borders around it.

For below-grade drainage, Drain Rock and 3/4" Drain Rock are clean washed stone with no fines, so water passes straight through. Both work in French drains, drywells and drainage layers behind retaining walls.

Base work still starts with Class 2 Base, the standard California base material and the local name for Class II base rock. Recycled base rock and crushed miscellaneous base do the same job under drives and pads. Top a compacted drive with Driveway Gravel, or lay Stone Screenings over a compacted base for paths and patios. In Covina, DG packs firm and stays walkable.

Ground and Conditions in Covina

The working season is long. Warm, dry weather suits base and paver work for most of the year, and winter storm days are the main interruption. Schedule your delivery around those storms, not through them.

Ground here runs from Top Soil to clay, with expansive clay in many basins and hills. That clay swells when wet and shrinks and cracks when dry, so it moves under slabs and paving. Compaction and drainage do the real work. Wetting that clay also swells it, which is why drainage stone around a slab matters as much as the base under it.

Erosion is the other half. Hillside runoff and slope failures show up in winter storms, and the first heavy rain can move burned hillside material as debris flow. Place rip rap where flow concentrates, and keep clean stone in drainage trenches so water has somewhere to go.
