Pro-Line’s Detectable Marking Tape is used for detecting, locating, identifying, and protecting buried utility lines for gas, water, sewer, telecommunication, and electrical markets. The width of tape used, is determined by the size of, and depth at which the underground utility line is buried. The depth at which detectable tape is buried, is determined by the width of the tape used.

  • DETECT: Aluminum core is detected through means of inductive locating.

  • LOCATE: Line is located and marked after inductive locating is performed.

  • IDENTIFY: Utility type is identified by both the APWA color-code and utility legend printed on the marking tape.

  • PROTECT: Detectable tape works 24 hours a day and year round, even if tape is not inductively located during excavation, the tape provides a “stop-sign” effect that is highly visible.
