Ground Penetrating Radar in Forensic Evaluations
What is Ground Penetrating Radar?
Ground Penetrating Radar (GPR) is a non-destructive testing (NDT) method that transmits radiofrequency waves to penetrate a multitude of different mediums. Reflected signals are then analyzed for changes in the scanned material.
How is GPR Used in Structural Analysis?
From a Structural Forensics standpoint, GPR can be used to evaluate sub-surface defects, voids, moisture, foundations, or to locate objects like rebar in concrete and masonry. This technology can be an efficient tool in construction claims, foundation investigations, discovering water intrusion, and other structural analysis.
