Bulk Material Delivery in San Leandro, CA

California Rock Supply handles gravel and aggregate delivery in San Leandro, CA, by the ton. The local base material here is Class 2 base, also called Class II base or Class 2 aggregate base, and it goes under driveways, parking pads, pavers and slabs. San Leandro sits in Alameda County on ground where sandy soils near the shoreline drain fast and heavy clay in the valleys holds water.

That split decides most material choices on a job here.

Materials for San Leandro Projects

Drainage is the first thing to solve on many San Leandro sites. Winter storms drop a lot of rain in a few events, and clay soil sheds it instead of soaking it up. Washed stone with no fines lets that water move, and the size you pick sets how fast it drains. Here are the sizes we deliver most, coarsest to finest.

For a French drain or a drywell, start with clean drain rock. Crushed stone with fines will clog and hold water instead of passing it, so keep the washed product for the drainage layer and use a filter fabric around it. For pipe bedding and tight spots, 3/8 inch crushed stone works well.

Downspout runs are the easiest fix on a wet lot. A short trench of drain rock carries roof water away from the foundation before it reaches the clay.

Ground and Conditions in San Leandro

The dry season from late spring into fall is the main window for base, driveway and paver work. Summer fog near the shore is not the problem. Winter rain and saturated clay are, because you cannot compact base over ground that is holding water.

On clay ground, excavate deeper than the finished base thickness and put a drainage layer or drain rock underneath so water has somewhere to go. Then compact the Class 2 base in lifts. On sandy ground near the shoreline, water leaves quickly and compaction is easier, but the edges of a pad still need to be held.

Steep slopes above town are the other winter concern. Hillside runoff and slides move fast in big storms, so slope work, culvert outlets and creek banks are worth armoring with RipRap before the rain arrives rather than after. Timing a delivery matters here: get base and drainage stone on site while the ground is dry and workable.

Delivery to San Leandro and the Surrounding Area

Order online and choose your material by the ton or by the cubic yard. Bulk delivery to a San Leandro site is a dump truck dropping loose material, so plan where the pile lands and keep it clear of the street and storm drains.

We also deliver across Alameda County, including Oakland, Fremont, Hayward, Berkeley and Livermore. Lead time depends on your material and the size of the load, so order ahead when a pour or a paver install is scheduled.

Questions About Material in San Leandro

Do you deliver Class 2 base to San Leandro, CA?

Yes. Class 2 base, also called Class II base or Class 2 aggregate base, is our standard base material and we deliver it in bulk to San Leandro and the rest of Alameda County. Order by the ton or yard, tell us where the truck can reach, and we will drop it on site for your driveway, pad or patio subgrade.

What gravel is best for a driveway in San Leandro?

Start with Class 2 base compacted in lifts, because clay ground here needs a base that holds up through the wet season. Top it with driveway gravel for the wearing surface. If your drive stays wet, put drain rock in a trench along the edge so water leaves instead of sitting under the stone.
