It isn’t always possible to use EMF locating techniques to locate buried services. In fact, with EMF equipment alone, some assets are essentially undetectable. Obviously, when we consider that some of these ‘hidden’ assets are either dangerous to those doing the digging and/or expensive to repair, it’s not good enough to leave them undetected and hope for the best.
GPR (Ground Penetrating Radar) systems enable operators to detect underground utilities, particularly non-conductive pipes and ducts, using high-frequency Radar. When locating underground utilities, GPR can be a valuable complement to EMF cable and pipe locators.
We use Radiodetection’s RD1500, an innovative GPR system that uses ultra-wideband 250MHz, specifically chosen for effective utility locating. This GPR product features external GPS and a high-resolution touch screen. For connectivity and ease of reporting, it has onboard Wi-Fi and a USB port. Additionally, the RD1500 allows us to create depth slices and review our locate path on the screen while on-site, and selectively enhance shallow/small, medium depth/size, or deep/large targets using the proprietary FrequenSee™ technology.
