Services
Geotechnical Engineering
Our geotechnical engineering services deliver comprehensive foundation design criteria, slope stability assessments, and subsurface exploration solutions. Utilizing advanced engineering software and 40 years of regional expertise, we ensure project compliance with California building standards. Our team conducts detailed site investigations and provides tailored recommendations for optimal construction performance.
Engineering Geology
Specialized geological hazard evaluations and fault trench studies help mitigate risks across diverse terrains. We analyze coastal bluff retreat patterns and ground movement indicators using historical data from our extensive resource library. Our services meet municipal code requirements while maintaining structural integrity for developments in California's complex geologic environments.
Construction Monitoring
We provide field testing including nuclear gauge compaction, concrete sampling, and soil stabilization monitoring throughout California. Our certified technicians ensure construction adherence to geotechnical specifications, performing real-time assessments of foundation excavations and ground reinforcement systems. This proactive approach maintains safety and investment protection for developers.
Soil Laboratory Testing
Our in-house soil laboratory conducts ASTM-standardized testing on moisture content, density, shear strength, and consolidation properties. With Proctor compaction curves and Atterberg limit analyses, we deliver accurate material behavior predictions for construction projects. The facility supports Northern California operations through rapid turnaround sample processing.
Peer Review Services
Through ASFE-recognized peer review programs, we audit geotechnical designs and engineering practices across the western United States. Our reviews identify potential design improvements and ensure compliance with evolving safety standards. This service benefits both engineering firms seeking validation and municipalities requiring independent technical assessments.
