What is Ground Penetrating Radar?
Ground penetrating radar (GPR) is a technology for indirectly looking at underground objects and other underground structures. The information or data received by GPR is like an x-ray or map of the underground. Ground penetrating radar (GPR) is a non-destructive geophysical method that produces a continuous cross-sectional profile or record of subsurface features, without drilling, probing, or digging. The GPR cross-section shows the ground surface at the top of the profile, and the reflections of subsurface geologic units and objects to a certain depth at the bottom.
UtilityDetection/Utility Survey/Underground Utility Mappingis a two-step process, employing both Radio Detection and GPR. Our goal is to identify the type and location of these utilities in order to prevent damage to them and the surrounding environment as well as protect your workers on the job site.
Benefit:
In as much as the disruption of the project schedule can cause a direct impact on the bottom line unforeseen repairs can cause equal impact. Material and repair cost for a damaged underground utilities can range from thousands to tens of thousands of dollars. The budget impact is not simply from the material and expertise needed for the repair the underground utility, but to pay for the service interruption to local business and other entities which rely on that utility for day-to-day operations. Most contractors have heard the troubling stories of service interruptions whose “interrupt cost” put the at fault contractor out of business. Again, the “unforeseen” and “unpredictable” can dictate the overall profitability of the project.
Ground penetrating radar can also provide untold cost savings by locating the utility line before the dig begins. It can help determine what a main power feed is located below the concrete and ensure that there is zero downtime for the facility and the owner of your project. By simply taking a few extra hours before the digging or cutting begin to have the area scanned, imaged, and inspected by an expert technician could represent tens of thousands of dollars in cost savings.
