Ground Penetrating Radar

What is GPR?
Ground penetrating radar operates by transmitting hi-frequency EM (electro-magnetic) pulse energy into the ground or concrete via an antenna, much like a fish finder on a boat.

How Does GPR Work?
When the GPR signal is reflected back to the antenna by materials with contrasting electrical (dielectric and conductivity) and physical properties, the user can analyze the reflected signals and can then pinpoint important targets or areas of concern.

Is GPR Harmful?
Ground penetrating causes no harm to the operator or anyone in the area. The output is approximately 1 1/100th the power of a cell phone, or 1% the power of a cell phone. Ask if the GPR is FCC certified.

How accurate is GPR?
GPR is very accurate. The accuracy of GPR is solely a by product of user set-up and interpretation.

Is GPR like Concrete X-Ray?
GPR is not concrete radiography. Radiography is dangerous, time consuming, and costly.
