GeoPhysi
Professional soil testing and geophysical survey services for foundations, tunnels, and slope designs.
Know the Ground, Build with Confidence
From boreholes to resistivity tests, we reveal what’s beneath—clearly and accurately.
GeoPhysi is GEOOE’s technical arm for soil investigation and geophysical exploration. We offer comprehensive site investigation packages including SPT, CPT, borehole logging, resistivity tests, and MASW. Powered by expert field teams and mobile rigs, GeoPhysi helps clients understand subsurface conditions before construction begins. Working closely with GEOOE’s monitoring and AI teams, GeoPhysi ensures seamless integration between investigation and monitoring strategies. Whether for landslide-prone slopes, metro tunnels, or building foundations, our precise data and professional reports give engineers the confidence to design safely and economically. We are committed to high-quality field execution and continuous technical innovation.
EXAMPLES OF SERVICE SCENARIOS
Foundation Soil Profiling. Before constructing a commercial tower in Shenzhen, the client hires GeoPhysi to drill boreholes and conduct SPT/CPT tests. Lab analysis of soil samples provides strength parameters. Based on this, the designer chooses a pile foundation and avoids costly over-design.
Resistivity Survey for Landslide Study. In a rural mountainous area, GeoPhysi runs 2D electrical resistivity tomography (ERT) to map subsurface moisture levels and detect slip surfaces. The results help the government identify hidden landslide zones and prioritize slope stabilization works.
Tunnel Route Feasibility Study. An underground transit line is planned across varying geology. GeoPhysi performs MASW and borehole logs along the proposed route, detecting rock layers and groundwater tables. The data helps the designer adjust tunnel alignment and reduce excavation risks.
Soil Investigation for Solar Farms. GeoPhysi is commissioned to study soil bearing capacity for a large-scale solar power installation. CPT tests and density measurements confirm that shallow foundations are viable—saving cost and time during project development.
