Minerallac 94605 Non-Detectable Underground Warning Tape, 3" x 1000', Red

The Minerallac 94605 is a 3" x 1000' roll of non-detectable underground caution tape, printed with bold black "CAUTION: BURIED ELECTRIC LINE BELOW" lettering on a bright red 4 Mil background. Designed for direct burial above underground electrical lines, this warning tape alerts excavators and utility crews to the presence of buried electric infrastructure before digging occurs, helping prevent accidental strikes, service interruptions, and safety hazards. The red color coding follows standard industry conventions for electrical line marking, while the continuous roll length and durable 4 Mil construction make it suitable for long trench runs and large-scale underground electrical installations. Whether used on new electrical construction, utility trenching, or underground conduit and cable runs, this tape provides a simple, cost-effective layer of protection that supports safe digging practices for future excavation work.

Key Features

  • Roll Size: 3" wide x 1000' long roll provides extended coverage for long underground electrical runs, reducing the number of rolls needed per job.
  • 4 Mil Thickness: Substantial 4 Mil gauge construction offers durability for burial applications and resists tearing during backfill.
  • Non-Detectable Tape: Standard non-detectable underground tape designed for visual warning when trenches are reopened, rather than electronic locating.
  • High-Visibility Red Background: Bright red tape color aligns with common industry color coding for electrical line identification.
  • Bold Black Warning Text: Clearly printed "CAUTION: BURIED ELECTRIC LINE BELOW" lettering in black for maximum legibility when a trench is excavated.
  • Buried Electric Line Marking: Purpose-built to be installed above underground electrical lines as a caution barrier for future digging.

Minerallac 94605 – Frequently Asked Questions

1) Will non-detectable warning tape work if the utility locator needs to find the line later?
No. The Minerallac 94605 is non-detectable tape, which means it has no metallic foil core and will not respond to an electromagnetic locator. It only warns a crew visually once the trench is reopened and the tape is exposed. If your spec or utility requires the tape itself to be traceable from the surface, you need detectable (foil-backed) tape instead, or a separate tracer wire in the trench.
2) Does red underground tape mean electrical, and what does the 94605 print say?
Red is the standard utility color code for electric power lines, and that is what this tape is for. The Minerallac 94605 is bright red with black lettering reading "CAUTION: BURIED ELECTRIC LINE BELOW". Use a different color for other utilities: blue for potable water, yellow for gas and fuel, orange for communications, green for sewer.
3) Is 4 mil tape heavy enough to survive backfill over a conduit run?
4 mil is the common contractor-grade gauge and the 94605 is built at that thickness to resist tearing as backfill is placed. It is polyethylene, so it won't rot in the ground. Standard practice is to lay it on compacted fill roughly 12 to 18 inches above the conduit, not directly on the duct, and to avoid dropping rock straight onto it. If a utility spec calls for 5 or 6 mil, this roll will not meet it.
4) Can I use this warning tape above a direct-buried cable as well as PVC conduit?
Yes. The 94605 is a buried-marker tape, not a cable wrap, so it goes in the backfill above whatever is in the trench, PVC conduit, duct bank, or direct-burial cable. It carries no electrical or mechanical protection function at all, it just flags the line for the next crew that digs.
5) What material is Minerallac underground warning tape made of, and does it contain heavy metals?
It's heavy metal-free polyethylene. That matters on government, school and healthcare jobs where buried plastics have to be free of lead and other heavy metal pigments, and it's the reason the printed red stays legible in soil rather than leaching out. Country of origin is China.
