Hazard Barrier Company is a manufacturer of marker tape with tracer wire for underground utility routes that need both clear visual warning and surface electronic locating. This detectable underground marker tape uses a printed PE/LDPE carrier with an integrated conductive tracer wire, helping excavation crews identify the warning layer and trace the buried route before reaching the service line. It is placed above buried services such as electric cables, gas pipes, water lines, sewer routes, telecom ducts, and fiber optic conduits.

Product Overview
Marker tape with tracer wire is made for underground projects where buried assets must stay identifiable after the trench has been closed. The printed tape gives a visible warning during future excavation, while the built-in wire forms a conductive path that can be followed from the surface with suitable locating equipment. For plastic pipe, HDPE conduit, inactive cable, fiber optic duct, and other non-metallic services, this structure gives more practical locating support than ordinary non-detectable warning tape.
The PE/LDPE carrier is flexible enough for long trench runs and stable enough to unwind without excessive twisting. Typical tape thickness can be selected from 100 um - 300 um, with a reference thickness tolerance of +/-10%, depending on film grade, width, and project specification. A common PE warning tape with tracer wire uses printed film laminated with stainless steel wire or coated conductive wire. Wire diameter is usually selected around 0.3 mm - 0.7 mm. Straight wire is suitable for simple utility corridors, while wave wire helps reduce stress when soil movement or longer runs place tension on the tape.
Custom printed utility marker tape can carry repeated legends such as electric cable below, gas line below, water pipe below, sewer line below, or fiber optic cable below. Colors can follow APWA-style utility identification, including red, yellow, blue, green, orange, purple, or project-specific color matching. For field readability, the printed warning text should remain clear along the roll, especially when the tape is used as the first visible signal before the buried service is exposed.
Benefits
- Combines visible warning and electronic route locating in one underground warning tape with wire.
- Helps identify plastic pipes, ducts, inactive cables, and fiber optic routes that are difficult to detect directly.
- Integrated tracer wire supports signal tracing when roll joints are connected and continuity is checked before backfill.
- Repeated printed legends help crews recognize the buried service type before reaching the asset.
- PE/LDPE carrier is suitable for normal trench backfill, damp soil exposure, and long-run placement.
- Width, roll length, color, wire layout, and warning text can be adjusted to match project drawings and utility color requirements.
How Does the Integrated Tracer Wire Help Locate Buried Services?
The tracer wire is not added only for appearance. It creates a conductive route that can carry a locating signal along the buried line. When two rolls are joined, the wire connection should remain electrically continuous; otherwise, the signal may stop at the joint. Continuity checking before final backfill is recommended, especially for long trench runs or projects using 250 m and 500 m rolls. Before bulk installation, sample rolls can also be checked for signal response, print clarity, roll joint handling, and wire end accessibility. These checks are useful for plastic pipe, HDPE conduit, fiber optic duct, irrigation line, and other services that cannot be located easily by direct metal detection.
Application
- Buried electric cable route marking for roads, plants, and building projects
- Gas, oil, and fuel pipeline warning above service corridors
- Potable water pipe and sewer line identification in municipal work
- Telecom duct and fiber optic cable route locating
- Irrigation pipe, HDPE pipe, and other non-metallic utility marking
- Civil trench backfill projects that need visual warning and surface locating support
Where Should Marker Tape with Tracer Wire Be Installed?
Marker tape with tracer wire should be installed above buried services, not used as a pipe wrap or mechanical protection layer. After the cable, pipe, duct, or conduit is placed, an initial layer of backfill is compacted first. The tape is then unrolled along the route between the buried asset and the final ground surface. This placement gives excavation crews an early warning before they reach the service, while the tracer wire keeps the route traceable from above ground.
For practical installation, the printed side should face upward where possible so the warning legend can be read during excavation. The wire end should remain accessible when a locating connection point is required. On longer runs, width tolerance, roll length tolerance, and joint handling should be checked before bulk use, because poor alignment or broken continuity can affect both the visual marking and the electronic locating result.
FAQ
What is the difference between detectable and non-detectable marker tape?
Detectable marker tape includes a conductive element such as tracer wire. Non-detectable tape mainly provides visual warning and cannot provide the same route tracing support.
Can the warning message be customized?
Yes. Text, color, width, roll length, and service legend can be adjusted for electric, gas, water, sewer, telecom, fiber optic, or project-specific utility routes.
Does the tracer wire replace a full tracer wire system?
No. It supports route locating for warning tape applications, but critical utilities may still require a dedicated tracer wire design based on project specifications.
Should continuity be checked before backfill?
Yes. Continuity checking helps confirm that the locating signal path is connected across the installed run, especially where two rolls are joined.
