What types of utilities can Master Locators find?

Master Locators specializes in the safe and accurate location of all underground utilities. We utilize an extensive array of equipment to help us locate even the most complicated underground utilities. Most utilities can be located using a standard digital locator. For other commodities, more specialized equipment is needed.

The Digital Locator

We use both Radio Detection and Subsite Brand digital locators. Our electromagnetic equipment works by applying a low radio frequency to any conductive utility directly with leads, or indirectly with an inductive clamp, or simply by placing our transmitter box in the vicinity of the underground utility to be located. A Digital Receiver is used to detect the location where the applied radio signal is being transmitted.

Ground Penetrating Radar

Ground Radar is used when no connection to a utility is possible, or when the utility is of a non-metallic material. Common underground utilities that we locate with GPR can include terra cotta pipes, plastic pipes, 3 Phase Primary Electric (when no grounding structure is present), underground storage tanks, and reinforced concrete pipes. We also use GPR to verify our work results, and to ensure that all locatable underground utilities have been marked out for any given work area.

Split-Box Digital Locator

A split-box locator can be used to help identify the presence of underground metallic utilities and structures (such as former pads and storage tanks) when no connection point is evident. We scan an area in a grid like pattern, searching for area of conductive re-activity. Once an area has been identified, further investigation may be necessary to further identify the unknown commodity. Water pipes and UST‘s are among the most common utilities located with this technique.

Traceable Duct Rodder

When given access to a gravity sanitary sewer or storm water pipe, we can insert a traceable duct rodder into the pipe. This will allow us to utilize our digital locators, even if the pipe is non-metallic. This is the most reliable and preferred method for underground utility mark outs. When access to a storm or sewer pipe is not available, we can then try to locate the utility with Ground Penetrating Radar.

500′ Extension Wire

With the use of a 500 foot extension ground wire, we can create a forced loop between surface features to help even the most difficult underground utilities get located quickly and accurately.
