Why Subsurface Mapping Solutions use 3D Multi-Array GPR

Written on the 12 July 2023

In the utility locating industry in Australia, Ground Penetrating Radar (GPR) technology has revolutionized the process, increasing both efficiency and accuracy. However, as technology continues to evolve, the advent of Multi-Array GPR, also known as multi-channel GPR, has brought about a new dimension to the field. 

Traditional GPR uses a single antenna to send and receive signals, providing a two-dimensional image of the subsurface. While this approach has been beneficial in utility detection, it can sometimes miss smaller or deeper utilities due to its limited view.

On the other hand, Multi-Array GPR uses multiple antennas simultaneously, enabling the creation of three-dimensional images (3D GPR). This advanced technology offers substantial improvements over its predecessor in terms of utility detection. The major advantage that Subsurface Mapping Solutions(SMS) has with Multi-Array GPR is its ability to provide a more comprehensive and detailed layout of utilities beneath the surface. This 3D visualization enhances the detection capabilities, minimizing the likelihood of missing any utility lines.

In the context of Queensland and Australia more broadly, where diverse ground conditions may pose challenges to utility detection, the Multi-Array GPR proves to be particularly advantageous. The enhanced ability to detect utilities under varied soil types, including sandy, clayey, or rocky terrains, ultimately leads to safer and more effective excavation projects.

It can identify metallic utilities such as gas pipelines, water mains, and electrical conduits. Additionally, it is equally effective in locating non-metallic utilities that might escape traditional detection methods, including PVC water pipes, fiber-optic cables, and drainage systems. Furthermore, Multi-Array GPR is also capable of providing vital information about other subsurface features, such as underground storage tanks, septic systems, and voids. This broad detection range underscores the superiority of Multi-Array GPR in utility detection, ensuring a comprehensive understanding of the subsurface infrastructure. 

In conclusion, while traditional GPR has been instrumental in utility locating, the integration of 3D Multi-Array GPR with StreamDP, paired with IQMaps as employed by SMS, marks a significant step forward. By providing detailed 3D images, it significantly enhances the accuracy of utility detection, making it an invaluable tool in the Australian context.
