& Engineering Geology

SOCOTEC’s geotechnical engineering services are essential for understanding subsurface conditions and mitigating potential risks associated with soil, bedrock, and groundwater. Our expertise includes: 

• Site investigations, soil testing, field instrumentation and monitoring 

• Foundation analysis and design 

• Slope stability and landslide assessment 

• Earthquake, seismic hazard, time history analyses, and liquefaction evaluation

• Retaining structures, shoring, and deep excavation design 

• Ground improvement and soil stabilization 

• Pavement designs and subsurface drainage solutions 

• Hydrogeologic assessments 

Utilizing advanced geophysical technologies, SOCOTEC provides non-invasive subsurface imaging and analysis to direct and optimize engineering and construction decisions. Our geophysical capabilities include: 

• Seismic surveys (refraction, reflection, MASW, and HVSR) 

• Ground-penetrating radar (GPR) for utility and structural mapping 

• Electrical resistivity and induced polarization surveys 

• Electromagnetic and magnetic surveys for geological and environmental assessments 

• Microgravity surveys for void detection and subsurface density variations 

• Borehole geophysical logging for in-depth subsurface characterization 

• Vibration and blast monitoring 

• Marine sub-bottom profiling 

• Crosshole sonic logging 

• Thermal soil resistivity 

Our engineering geology services provide critical geological insights to support infrastructure planning and development in diverse environments. Our offerings include: 

• Geological hazard assessments, including landslide, rockfall evaluations, and expansive soils 

• Fault trenching, rupture, and seismic hazard analyses 

• Hydrogeologic studies, groundwater modeling, dewatering, and aquifer characterization 

• Geological mapping and terrain analysis 

• Forensic geologic investigations 

• Rock mechanics and tunneling support
