Frequently Asked Questions
Ground Penetrating Radar
Radar is used for utility locating and archaeology purposes too. It can penetrate up to 100 feet depending on the antenna used. A typical utility application configuration will go to a depth of 10 – 15 ft deep in scanning depending on the soil type and moisture level. Radar can be highly accurate at location, while identifying underground objects requires experience and skill.
While some of the GPR energy pulse is reflected back to the antenna, energy also keeps traveling through the material until it either dissipates (attenuates) or the GPR control unit has closed its time window. The rate of signal attenuation varies widely and is dependent on the properties of the material through which the pulse is passing.<
Members of our trained team are able to identify the type of utility by tracing it using Utility Locate Equipment other than GPR. They are also able to identify features, such as control boxes, valves and meters. However, if the locators are not able to direct connect to the specific utility they may not be able to conclusively identify it.
General Questions
Hiring GPR Contractors vs Alternatives
Metal detectors and GPR are completely different technologies. Also, metal detection has depth limitations which makes it insufficient for commercial inspections, while GPR can reveal obstructions up to 100 feet underground.
