3M Locators and Markers provide a complete system for locating, marking and mapping vital underground assets.
From markers that give an exact path and estimated depth of underground utilities, to markers that store information, to utility locators that interface with GPS/GIS field mapping instruments, 3M offers the precision tools needed to manage your assets. Together, they provide a complete solution with the performance and reliability you trust from 3M. Learn more about 3M’s utility locating products, line locator industry solutions, or utility locator resources.
Quickly pinpoint the location of buried facilities with the 3M™ Electronic Marker System (EMS) for Telephone. Using 3M EMS markers during construction, installation and maintenance virtually eliminates the time consuming search for hard-to-locate facilities. Markers used for communications location are colour-coded to APWA standards for visual reference and have their own frequency, helping reduce the risk of accidentally locating and excavating other buried facilities. For communications utilities, all telephone locator markers are orange and CATV markers are orange/black.
3M EMS telecom cable locator series can be used to locate:
Save time and money by quickly pinpointing the location of buried facilities, with the 3M™ Electronic Marker System (EMS). 3M markers operate even in the presence of metal conduit or pipe, metallic conductors, fences, AC power lines and electronic markers of other utilities. All EMS Markers used for gas pipe location are color-coded to APWA standards for visual reference and gas utilities have their own frequency, helping reduce the risk of accidentally locating and excavating other buried facilities. All gas pipe location markers are yellow in colour.
3M EMS gas pipe location series can be used to locate:
Know where to dig! The 3M™ Electronic Marker System (EMS) helps save electric utilities time and money by enabling field crews to quickly pinpoint the location of underground electric facilities, including cable runs, splices, vaults, conduits and road crossings. 3M also offers wide product support and service for increased safety, performance and reliability.
EMS markers used for underground electric cable location are colour-coded to APWA standards for visual reference and power utilities have their own frequency, helping reduce the risk of accidentally locating and excavating other underground electric facilities. For power utilities, all underground electric cable markers are red in colour.
3M EMS Power series can be used to locate:
Find it the first time! The 3M™ Electronic Marker System (EMS) for Water and Wastewater helps save time and money by enabling field crews to quickly pinpoint the location of buried facilities including valves, bends, clean-outs and road crossings. Using EMS markers for water and sewer pipe location during construction, installation and maintenance virtually eliminates the time consuming search for hard-to-locate facilities.
3M EMS markers used for water and sewer pipe location are color-coded to APWA standards for visual reference and water utilities have their own frequency to reduce location errors. For water and sewer pipe location, markers are colour coded as follows:
Water Utility: Blue
General Purpose/Reclaimed Water: Purple
Wastewater Utility Markers: Green
