Geotechnical engineering across the San Francisco Bay Area.
The ground changes dramatically across the Bay — from bay mud and fill at the shoreline to franciscan bedrock and landslide-prone hillsides above the faults. We know the local geology in each of these areas and design for what is actually underfoot.
Cities we serve
Explore the local geology, faults, and typical projects for your city:
Regional coverage
Oakland & the Oakland Hills
Steep hillside lots, Hayward fault proximity, and landslide-prone slopes make slope stability and drilled-pier foundations the norm here.
Berkeley & Albany
Hillside homes above the fault and soft ground toward the bay margin — projects often combine slope work, expansive-soil design, and seismic evaluation.
San Francisco
From bedrock hills to deep bay mud and artificial fill, SF sites swing between simple footings and demanding deep-foundation and liquefaction problems.
San Jose & the South Bay
Alluvial valley soils, expansive clays, and localized liquefaction shape foundation and ground-improvement design across the South Bay.
Contra Costa County
Expansive Orinda and Concord-area clays and hillside grading drive much of the foundation and slope engineering in the county — our home base.
Marin County
Coastal hillsides, franciscan mélange, and landslide history make geohazard and slope-stability assessment especially important in Marin.
The Peninsula & San Mateo County
Bay-margin fill and mud near the shoreline transition to firmer ground in the hills, requiring site-specific foundation and seismic design.
Tri-Valley (Dublin, Pleasanton, Livermore)
Valley alluvium, expansive soils, and active local faults inform foundation and seismic recommendations throughout the Tri-Valley.
Services in every area
Wherever your project is in the Bay Area, we bring the full range of geotechnical services:
