Description
This high visibility underground tape is designed for marking and detecting buried electric cables before excavation begins. It is widely used by contractors, utilities, and civil engineers to help prevent accidental strikes to live services during groundwork.
Made from tough polypropylene and containing stainless steel wire strands for traceability, this tape can be located from the surface using standard cable detection tools. It features a bright yellow background with bold black lettering reading “CAUTION ELECTRIC BELOW,” offering clear visual communication of the hazard.
At 150mm wide and 100 metres long, it offers effective coverage across trenches, ducts, and underground cable runs. Designed to comply with EN 12613 standards, the tape is suitable for long-term burial and resists rotting and degradation under soil.
