What Sacramento ground means for concrete driveways
Highly variable - river-deposited silts and sands near the American and Sacramento Rivers, expansive clay lenses further from the channels.
Driveways near the American and Sacramento river corridors sit on sandy alluvium that drains well and compacts predictably. Move east toward Rancho Cordova, south to Elk Grove or north to Antelope and expansive clay takes over. The same slab detail is not appropriate in both places, which is why we look at the ground before quoting a section rather than after.
- Older central neighborhoods often have thin, unreinforced original driveways poured directly on native soil.
- Mature street trees lift sidewalk panels citywide, which is the most common trip-hazard notice we respond to.
- Right-of-way work inside city limits requires an encroachment permit and inspection against the city standard detail.
- Narrow side-yard access in Midtown and East Sacramento means compact equipment and hand removal on most backyard projects.
