Geotechnical & Soil Engineering Services in San Francisco, CA
San Francisco Bay Area
We provide geotechnical soil investigations for residential and light commercial projects throughout San Francisco, working with homeowners, architects, and contractors to meet Department of Building Inspection (DBI) requirements.
San Francisco's geology varies block by block — from stable bedrock in the western hills to soft, compressible "Bay Mud" and artificial fill in low-lying and shoreline neighborhoods, many of which fall within USGS- and state-mapped liquefaction hazard zones. A site-specific soil investigation is essential in the city, since foundation recommendations that work on one block can be inappropriate a few blocks away.
