Ground Penetrating Radar (GPR) for Dam Monitoring - GSSI

GPR systems work by sending a tiny pulse of energy into a material via an antenna.

An integrated computer records the strength and time required for the return of any reflected signals. Subsurface variations will create reflections that are picked up by the system and stored on digital media. These reflections are produced by a variety of material such as geological structure differences and man-made objects like pipes and wire.

A wide range of GPR equipment is available for dam assessment and evaluation applications. While a lower frequency antenna can collect deeper data, it cannot provide the resolution to image small targets or closely spaced soil boundaries available with a higher frequency antenna. GSSI offers a full suite of antennas to accommodate various project requirements.
