Underground Utility Locating Using GPR
Util-Locate uses the latest equipment and cutting edge technologies. With over 13 years of experience, Util-Locate shows its expertise to produce cost-effective fast, efficient and accurate GPR surveys solutions.
Util-Locate can determine the most suitable survey methodology based on clients’ specification, and are proud to be able to provide onsite real-time data.
Ground Penetrating Radar (GPR) is a non-intrusive surveying technique used to locate utilities, rebar, conduits, voids, and other features below the surface.
GPR uses pulses of energy to image the subsurface. An integrated computer records the strength and time required for the return of reflected signals, and stores this data on digital media. Differences occur in natural and man-made materials such as geological structures, pipes and wire.
As a non-destructive and dynamic survey technique, GPR can be applied on a variety of surfaces including rock, soil, ice, fresh water, pavements, and concrete structures. Read more about electric line locator.
The benefits of using Ground Penetrating Radar
GPR is able to detect metallic and non-metallic services such as polyethylene water and gas pipes as well as utilities such as fiber-optic cables which are not normally traceable using any other method.
Using GPR alone we cannot guarantee finding or identifying all buried services, but when used in conjunction with Electro-Magnetic detection, the most complete and comprehensive answer available is produced.
Benefits of Ground Penetrating Radar
