Infrasense Identifies Subsurface Obstructions to Clear Drilling Locations in Real-Time in Southeastern Massachusetts

Infrasense cleared sites for boreholes to be drilled using ground penetrating radar. The goal of the survey was to identify locations where the drill would be clear of any underground utilities and boulders.

The goal of the survey was to identify locations where the drill would be clear of any underground obstructions including utilities and boulders.

This Spring, Infrasense completed a job in its home state of Massachusetts. A two-person GPR team surveyed prescribed areas and gave the go ahead in real-time to a drill team onsite. About 10 holes were drilled for the future installation of power lines. The goal of the survey was to give site developers the current subsurface data to safely drill around obstructions, such as utilities and large boulders.

The ground penetrating radar (GPR) survey was performed using a 200 MHz antenna system, which can “see” about 30 feet beneath the ground surface under favorable conditions. The antenna is controlled by a GSSI SIR-4000 data acquisition unit. Obstructions are marked out onsite and later confirmed with post-processing at the office. A report is delivered to the client describing the data collection equipment and procedures, and documenting the locations of identified obstructions.
