What is GPR?

What is Ground Penetrating Radar (GPR)? 

Ground Penetrating Radar (GPR) is the most advanced technology available for sub-surface utility investigations and concrete structure scanning. Here at Utility Survey Corp. we use it to “see” into the ground and inside of concrete structures to locate utilities, objects, and features. These are hidden potential dangers that can seriously impact our client projects should they remain undetected.  

GPR can also detect non-objects such as hollow cavities (voids). If conditions are favorable, GPR can “see” virtually anything.

The GPR radio frequencies (also known as radar waves or signals) bounce off any object they encounter and are received back at the antenna. The signals are then transmitted by a connecting wire from the antenna to a dedicated on-board computer where they are processed, analyzed, and displayed on the screen of the computer.

Ground Penetrating Radar (GPR) is a technology that pulses radio frequencies, by way of an antenna, into a medium such as the ground (or a concrete structure in the applications Utility Survey Corp. uses it for) to detect buried objects. The target objects can be made of any material at all such as plastic, metal, wood, stone, concrete etc.
