GPR

Ground Penetrating Radar (GPR) systems can efficiently provide high precision mapping of underground utilities and other features without the need for excavation.  GPR has the ability to map both conductive and non-conductive utilities.  It can also help to map natural features such as voids, ground water levels, bedrock and soil layers.  Let us help you discover how GPR can be used to reduce timelines and costs on your next project.

4Sight utilizes various systems to collect GPR data.  Multi-Channel Ground Penetrating Radar (MCGPR) allows for the collection of data in a tow behind configuration that can collect data at driving speeds. The versatile system can also be configured in a pushcart version to allow for collection in boulevards and off-road conditions. Both configurations utilize 18/8 channel multi array antennas for scanning.  The final product is a 3D block of data with superior quality.

Our traditional GPR unit uses dual channel 400 MHz (LF) and 800 MHz (HF) antenna and real-time sampling. The Lower frequency (LF) allows for deeper signal penetration and the higher frequency (HF) antenna improves signal resolution near the ground surface. Any anomalies identified will be marked on the ground for survey.
