Underground warning tape for excavation safety

Presco Underground Non-Detectable Tape is a 4 mil thick polyethylene film that alerts digging crews to buried fiber optic lines. The bright orange material carries black "CAUTION BURIED FIBER OPTIC LINE BELOW" printing for clear visibility. It is designed for construction, utility, irrigation and CATV projects where underground hazards exist. The non-adhesive tape unrolls directly into the trench without sticking to itself or tools.

Non-detectable material limits locating methods

Because the tape contains no metallic components, it cannot be located with standard electromagnetic pipe and cable locators. Excavators must rely on visual exposure during digging rather than electronic tracing. The product is intended for shallow burial between four and six inches below grade so it appears before the utility line is reached. Projects requiring traceable markers will need a detectable alternative.

Polyethylene construction resists soil degradation

The heavy-metal-free PE film will not turn black over time and withstands moisture, chemicals and temperature cycles in the ground. Supplied on a 1000 foot roll, it covers long trench runs with fewer joints. The three-inch width provides a broad visual target for backhoe operators and hand diggers alike. Rolls may arrive on a neutral or Presco-branded core depending on stock.

Questions about this item

Which width should I choose for my underground marking project?

The 3-inch wide roll provides clear visibility for marking buried fiber optic lines, while the 6-inch option offers broader coverage for wider trenches or areas requiring more prominent warnings.

What does the 1000 foot length mean when I'm laying tape in a trench?

A single 1000 foot roll lets you mark a continuous run of buried cable over a long distance, reducing the number of splices or overlaps needed during installation.

How does the non-adhesive polyethylene film perform once buried?

The 4 mil thick polyethylene resists underground elements, contains no heavy metals, and will not turn black over time, staying legible as a permanent warning layer.
