GROUND PENETRATING RADAR
Ground Penetrating Radar or GPR is the process in which a transmitter sends a pulse into the ground or structure and records the echoes that rebound off subsurface objects such as underground utilities, structural reinforcements, obstructions, voids, and more. GPR is an umbrella term that covers a broad range of specialized equipment, because of this it is important to understand the different types of GPR available on the market in order to maximize the amount of data that is relevant to your project and specific needs. At Axis Building Detection, we provide multiple variants of GPR to assist our clients in making informed and educated decisions based on what may be below. This increases job-site safety, reduces project costs, and greatly reduces the probability of costly damages commonly associated with excavation, coring, boring, cutting, and drilling.
HOW GROUND PENETRATING RADAR WORKS
During GPR, a radar unit will emit and receive thousands of signals per second which are then transmitted to a monitor. The results are then saved and stored for future review. Many GPR methods create visual slices of an image to generate a three-dimensional map with depth, soil type, and object locations as major features.
WHAT CAN GPR DO?
Ground-penetrating radar can map the subsurface to detect underground obstructions such as pipes, utilities, leaks, and line breaks in a way that is non-intrusive. The results of mapping with GPR can make a huge impact on the scope and direction of our construction projects.
GPR provides a complete picture of the job site, both above and below the ground. GPR can avoid potentially perilous situations from hitting a major utility such as a water main or a power line. Less digging is an advantage of use with GPR, saving clients time and money.
