Overview

Flowlines Detectable Underground Warning Tapes provide a reliable and highly visible safety solution for identifying buried utility services before excavation reaches critical infrastructure. Installed directly above underground lines, these tapes act as an early warning system—helping prevent accidental dig-ins, service disruptions, and on-site safety risks.

Manufactured with a corrosion-resistant metallic layer, the tapes enable accurate underground detection using standard locating equipment while delivering long-term performance in harsh soil and environmental conditions. Designed for infrastructure, utility, industrial, and commercial projects, they support safer excavation practices and regulatory compliance.
