What North Highlands ground means for concrete driveways
Hardpan-influenced soils that impede drainage and hold water near the surface in wet months.
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.
- Hardpan limits percolation, so surface drainage design is critical on new flatwork.
- Original slabs are often thin and unreinforced, favoring replacement over repair.
- Substantial multi-family stock generates ongoing walkway and ADA repair work.
- Straight access on most lots keeps demolition and placement efficient.
