Locating Buried Objects
Buried Object Location Surveys
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 to locate buried objects using geophysical methods.
The most common geophysical methods used to locate buried objects are ground penetrating radar (GPR) and electromagnetic (terrain) conductivity. These geophysical methods are non-destructive, and can locate buried objects quickly and effectively.
Ground Penetrating Radar Surveys
Ground penetrating radar (GPR) surveys can be conducted to locate 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 from buried tanks (UST) and buried utilities using GPR are shown below:

Electromagnetic Conductivity Surveys
Our company has conducted numerous electromagnetic conductivity (EM) surveys and metal detector surveys to locate ferrous (iron-based) and non-ferrous metal buried objects. A geophysicist operating an EM-31 and an EM-61 instrument is shown below:

Other ferrous and non-ferrous metallic buried objects, such as buried tanks (UST), drums, utilities, unexploded ordnance (UXOs), and buried treasure, can also be easily located with the EM-31 or EM-61 instruments.
