Services
Geotechnical Engineering
Our geotechnical engineering services address foundation design, slope stability, and earth retention systems for infrastructure projects. We analyze soil and rock mechanics to ensure structural integrity for buildings, dams, and transportation systems. Our team applies advanced numerical modeling to predict ground behavior under various loading conditions.
Earthquake Engineering
We provide seismic hazard assessments and ground motion evaluations for critical infrastructure. Our services include liquefaction mitigation, slope stability analysis, and soil-structure interaction studies for nuclear facilities and tall buildings. We employ advanced numerical modeling to predict seismic performance.
Hydrogeology Services
Our hydrogeology practice focuses on groundwater resource management and contamination assessment. We develop aquifer recharge programs, design monitoring systems, and model groundwater flow for environmental compliance. Our expertise includes dewatering solutions for deep excavations and subsurface construction.
Geophysical Surveys
We conduct non-invasive geophysical investigations using seismic, radar, and electromagnetic methods. Our services identify subsurface voids, map geological structures, and characterize soil/rock properties. We maintain proprietary equipment for seismic testing and ground penetrating radar applications.
Geological Assessment
Our geological assessments evaluate landslide risks, fault zones, and ground settlement potential. We perform field mapping, borehole analysis, and laboratory testing to characterize earth materials. Our reports inform mitigation strategies for infrastructure projects in geologically complex environments.
