150mm x 365m Non-Detectable Underground Warning Tape – High-Visibility Service Marking

Non-Detectable Underground Marker Tape – 150mm Wide x 365m Long – Printed Caution Message – For Subsurface Utility Indication

Our 150mm x 365m Non-Detectable Underground Warning Tape is a trusted solution for marking the location of buried utility lines, helping to prevent accidental damage during excavation. Designed for use across utilities, civil engineering and highway infrastructure projects, this tape is laid above buried services as a visual warning layer. Manufactured from tough, non-adhesive polyethylene, it withstands soil pressure and ground conditions, remaining visible when uncovered during maintenance or construction works.

Each roll is clearly printed with a bold caution message to indicate the specific type of service beneath, such as electric, gas, water, or fibre optic cables. The bright colours and 150mm width ensure maximum visibility, aiding compliance with industry best practices for underground service identification. This non-detectable tape is ideal where electronic detection isn’t required but visual identification is essential.
