Ground Penetrating Radar
Ground penetrating radar (GPR) is a non-destructive geophysical method that produces a continuous cross-sectional profile or record of subsurface features, without drilling, probing, or digging. GPR profiles are used for evaluating the location and depth of buried objects and to investigate the presence and continuity of natural subsurface conditions and features. Read more…
Buried Metal Detection & Electromagnetic Conductivity
Electromagnetic conductivity (EM) measures the conductivity of the subsurface which includes soil, groundwater, rock, and objects buried in the ground. Rapid and very accurate, EM instruments are used for a variety of purposes, including detecting underground metal petroleum tanks, metal underground utility pipes, contaminated groundwater and clay units.

Magnetometer Surveys
The presence of buried archaeological features, underground steel tanks and drums, and other ferrous buried objects can often be detected by a magnetometer survey, which detects small anomalies in the earth’s magnetic field which exist between buried structures and the surrounding substrate or bedrock.

Resistivity or Surface Resistivity
Surface resistivity can be used to study lateral changes and vertical cross sections of the natural hydrogeological setting. Surface resistivity can also be used to study contamination of soil and groundwater and to locate buried objects. A non-destructive geophysical survey method, surface resistivity can produce a detailed profile of the subsurface. Read more…
