Ground Penetrating Radar (GPR)
Ground-penetrating radar (GPR) uses radar pulses to image the subsurface. This nondestructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum, and detects the reflected signals from subsurface structures.
The successful detection and mapping of buried utilities involves the combination of several techniques, the results of which are synthesised down to a single interpreted plot. The techniques and methodologies used will primarily depend upon the required outcome for the survey, the site conditions and the type of pipes or cables being targeted.
Benefits of using GPR
- Effective site investigation
- Non-intrusive and safer way of mapping
- Alleviates the need for digging and the disturbance of sensitive sites
- Advantages over other techniques
- Early detection of warning signs
- Quick, reliable diagnosis
