What are JACKWIN Underground Warning Tapes?
Underground warning tape, also called cable marking tape or buried utility tape, is a non-adhesive, brightly colored tape primarily used for warning and detecting high-voltage cables, water pipes, gas pipelines, and communication lines. Our tapes can be used in both urban and rural areas, adapting to various soil conditions.
JACKWIN underground warning tapes feature the following functions:
- Notify the construction crew of the location of underground utilities to prevent accidental excavation and subsequent repair costs.
- Prevent construction personnel from sustaining personal injuries such as electric shock or gas poisoning.
- Effectively distinguish different sections of buried pipelines to reduce construction time, especially when project modifications are required.

Customize Your Underground Warning Tape
JACKWIN provides customization of all shapes, sizes, colors, and materials at competitive costs for your underground marking tapes to boost your business.
Advantages of OPP
OPP, also known as BOPP, is a plastic film produced through the processes of melting, extrusion, and stretching of polypropylene raw material.
OPP has the following advantages:
- It possesses superior mechanical tensile strength and rigidity to resist deformation.
- As the surface layer of detectable marking tapes, OPP provides a barrier against water vapor and offers exceptional moisture resistance.
- OPP film is lightweight and thin, enabling greater savings in transportation and material costs.
- The surface has a glossy finish, enhancing the tape’s visibility.
- OPP can withstand temperatures as low as -20°C and can be combined with PE or metallized film to provide oxygen barrier and heat resistance properties.


How do Underground Warning Tapes Work?
After laying underground cables and other facilities, you can mark their locations using warning tapes or cable tiles. When workers are performing tasks above, our tapes will alert them not to proceed further downward.
Here is how burial tapes work:
- JACKWIN Underground warning tape works on the fundamental principle of alerting construction personnel during excavation through its vivid colors and high-contrast OPP coating.
- Our tapes can stretch to disperse force under precise physical impacts from excavators or shovels.
- Our detectable warning tape, through the tracer wires embedded within its core, works in conjunction with metal detectors to help construction personnel locate buried cables.

How to Install Underground Warning Tape?
Step 1. Backfill sand over the pipeline and compact it until level, and ensure our tape is buried 2 inches (30 cm) above the pipeline.
Step 2. Be careful not to pull the warning tape too tight, and ensure sufficient clearance between the tape and the pipeline.
Step 3. Cover the warning tape with sand and soil, then backfill the trench.

How to Detect Underground Cables?
-
Cable Locator
JACKWIN cable locator is a metal detector, composed of a transmitter and receiver. It is capable of locating aluminum foil layers and tracer wires. The transmitter can emit a magnetic field signal toward the location of the cable. After the receiver picks up the signal, personnel can trace the signal path to identify the optimal direction for protection.
-
GPR
JACKWIN GPR automatically generates 3D images by transmitting electromagnetic waves and receiving the reflected signals. For non-metallic pipes and cable protection tiles, our GPR can map their shape and depth.
-
non-permanent spray paint or flags
For contracted public utilities, utility companies will use spray paint or flags to mark the locations of underground pipelines.

Underground Cable Tracer Wire vs Detectable Warning Tape with Tracer Wire


JACKWIN underground cable tracer wire is a bare or insulated metal wire buried alongside pipes or cables, also used for locating non-metallic pipes. Our tracer wire primarily consists of carbon-coated steel or high-carbon steel wire, along with HDPE or PVC insulation layers, and color-coded identification.
Advantages
- Actively emits strong radiation signals to provide precise positioning and depth measurement.
- High signal strength enables efficient transmission of radio frequency signals.
- An important structural component of the pipeline protection system.
Disadvantages
- Significant installation costs and subsequent detection expenses.
- High installation requirements, complex jointing and welding processes.
JACKWIN detectable warning tape with tracer wire is part of the underground facility visual warning system, whose detection function is passively triggered.
Advantages
- Low installation requirements, no electrical connections required.
- Low material costs and installation costs.
- Simultaneous visual warnings and detection positioning assistance.
Disadvantages
- Aluminum foil or stainless steel wire is fragile and exhibits poor electrical conductivity.
- Detection accuracy is relatively low and cannot provide precise positioning.
- It has lower durability than underground cable tracer wire and is prone to breakage.
Underground Warning Tape with Tracer Wire vs Aluminium Foil Detectable Tape


Differences
- JACKWIN Underground warning tape with tracer wire has higher resistance than aluminum foil, resulting in stronger and more stable signal strength.
- JACKWIN Underground warning tape with tracer wire costs more than aluminum foil but less than professional tracer wire.
How to choose?
- By balancing pipeline protection and budget constraints, JACKWIN underground warning tape with tracer wire enables you to clearly track pipeline routes in municipal, residential, industrial, and other underground pipeline projects.
- If you’re seeking lower costs and have already set a permanent marker, you can choose aluminum foil detectable tape to ensure a baseline level of security.
Workshop and Production
JACKWIN Factory possesses full-process underground warning tape production equipment, enabling assembly line manufacturing. We manufacture buried barricade tape using equipment such as a high-speed mixer, plastic film extruder, flexo printing machine, laminating Machine, cooling roller, slitting and rewinding machine.

This is our high-speed mixer, used for the pre-mixing process of plastic pellets prior to formal production.
This is our plastic film extruder. We melt the blended PE or OPP material into a fluid state and blow it into a uniformly textured film.
This is our flexo printing machine. We can emboss raised graphics onto PE or OPP films and then use rotary printing to enhance in-line processing capabilities.
This is our laminating machine, used for detectable warning tapes. We employ a hot-melt process to laminate aluminum foil with OPP/PE materials into a three-layer structure.
This is our cooling roller. We uniformly cool the initially formed plastic film, ensuring it does not curl, deform, stretch, or wrinkle.
This is our slitting and rewinding machine. We cut the finished plastic rolls to size, align them, and automatically curl the edges to produce the final product.
