Locating Buried Objects
Surveys for Locating Buried Objects
When locating buried objects, the usual methods of digging, probing, or drilling holes in the ground can be exhausting and time-consuming. Our company conducts investigative surveys for locating buried objects using geophysical methods.
The most common geophysical methods used for locating buried objects are ground penetrating radar (GPR) and electromagnetic (terrain) conductivity. These geophysical methods are non-destructive, and locating buried objects is quick and effective in most conditions.
Ground Penetrating Radar Surveys
Ground penetrating radar (GPR) surveys can be conducted for locating buried objects made of metal, wood, plastic, PVC, or any other material that has different electrical or conductive properties than the surrounding subsurface soils or rocks. The GPR system consists of a SIR-2 digital control unit and various transducers (antennas).
The GPR antennas can be vehicle-towed or hand-towed as shown below:


Typical responses for locating buried objects using GPR are shown below:

Electromagnetic Conductivity Surveys
Electromagnetic conductivity (EM) surveys and metal detector surveys can also be conducted for locating buried objects that are made of ferrous (iron-based) and non-ferrous metal. Geophysicists operating EM-31 and EM-61 instruments are shown below:
