GPR Surveys

Ground Penetrating Radar (GPR) is a non-intrusive geophysical method used to locate and map sub-surface features. It can be used on multiple surface types and is commonly used for the location of underground utilities. As well as concrete thickness, identifying ground make up and conditions, rebar detection, structural analysis and void detection.

The GPR works by emitting an electromagnetic pulse through the ground which is then reflected off underground structures and received back into the radar’s antenna. The receiver detects the returning signal, and the system software translates and displays these as images of the subsurface.

​

This makes it ideal for the detection of underground utilities as any disturbances in the ground can be relayed and accurately positioned with reliable depth information. This is commonly used for the detection of non-metallic utilities that cannot be located using RFL equipment. It is also an essential tool in improving quality codes in a PAS 128 survey.
