Geophysical Survey

Subsurface investigation and analysis for engineering, mining, and environmental applications.

Our geophysical survey services provide non-invasive subsurface profiling to support the planning, design, and risk assessment of construction, mining, infrastructure, and environmental projects. Combining field expertise with advanced laboratory data processing, we ensure accurate interpretation of underground conditions.

Field Survey Capabilities

We utilize a range of geophysical methods depending on the project objectives and site conditions:

• Electrical Resistivity Tomography (ERT) – for mapping soil layers, groundwater levels, and bedrock depth
• Seismic Refraction & MASW (Multichannel Analysis of Surface Waves) – for determining subsurface stiffness, layer thickness, and rippability
• Ground Penetrating Radar (GPR) – for detecting shallow utilities, voids, and buried objects
• Magnetic and Gradiometric Surveys – for detecting ferrous materials and archaeological features
• Induced Polarization (IP) – for mineral exploration and contamination studies

All surveys are conducted by experienced field teams using calibrated, industry-grade equipment with real-time quality control.

Laboratory & Data Interpretation

Our geophysics laboratory specializes in the processing, modeling, and interpretation of geophysical data using professional-grade software. Deliverables include:

• 2D and 3D subsurface profiles
• Geological cross-sections
• Inversion models and contour maps
• Layer depth and material property estimation
• Technical reporting for engineering and environmental consultants

Applications

Our geophysical surveys are widely used for:

Subsurface utility mapping (in conjunction with GPR)ontractor.

Site characterization for foundations and slope stability

Tunnel alignment and fault zone detection

Mineral and groundwater exploration

Environmental impact studies and contamination mapping
