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.
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.
