FORAGEO Geophysical Survey Services

Survey Methods

• Seismic Refraction & Reflection – Determine bedrock depth, layer thickness, and material stiffness for rippability assessment, foundation characterization, and mapping geological interfaces.
• Ground Penetrating Radar (GPR) – High-frequency EM imaging of shallow subsurface features such as buried utilities, voids, concrete reinforcement, and archaeological targets, typically to depths of up to ~30 m (site-dependent).
• Electrical Resistivity Tomography (ERT) – 2D/3D resistivity imaging to delineate geological boundaries, groundwater zones, and contamination plumes.
• Electromagnetic (EM) Surveys – Frequency- and time-domain EM for rapid conductivity mapping, detection of metallic objects, and delineation of contamination boundaries.
• Magnetic Surveys – Mapping variations in the Earth’s magnetic field to locate ferrous objects, identify geological contacts, and characterize subsurface structures.

Data Processing & Interpretation

All datasets undergo rigorous processing and quality control, including noise filtering, topographic corrections, velocity analysis, and inversion modeling. Senior geophysicists integrate geophysical results with geological information and borehole data to produce clear 2D profiles and 3D subsurface models. Deliverables include:

• Methodology and acquisition parameters
• Data quality assessment and processing workflow
• Interpreted cross-sections and models
• Practical recommendations for design and construction

Key Applications

• Site Investigation – Pre-construction ground characterization, bedrock profiling, and anomaly detection for buildings, bridges, and infrastructure.
• Utility Detection & Mapping – Non-destructive mapping of buried pipes, cables, tanks, and other services prior to excavation.
• Groundwater Exploration – Identification of aquifers, water table mapping, and groundwater flow assessment for well siting and resource management.
• Environmental Assessment – Delineation of contamination plumes, buried waste detection, and monitoring of remediation.
• Mining & Quarrying – Mineral targeting, overburden thickness estimation, and rock quality assessment for quarry and mine planning.
