Product Name

Underground Utility Warning Tape 365m x 100mm – CAUTION TELEPHONE CABLE BELOW – Green LLDPE

Overview

Designed to support safe excavation practices, this underground utility warning tape provides a clear visual indicator of buried telephone and communication cables. Manufactured from rot-resistant Linear Low-Density Polyethylene (LLDPE), it remains legible and intact underground, helping excavators identify services before tools reach the cable and reducing the risk of outages, repairs, and project delays.

Key Features & Benefits

  • High-visibility green tape with clear “CAUTION TELEPHONE CABLE BELOW” legend.
  • Colour coded in accordance with NJUG guidelines for telecom services.
  • Rot-resistant and acid-resistant LLDPE for long-term underground durability.
  • Non-adhesive design intended for loose placement in trench backfill.
  • Provides an early visual warning when installed approx. 300mm above the service line.
  • Helps reduce costly communication outages and reinstatement works.

Installation & Applications

Suitable for utilities, civils, highways, and groundworks projects involving buried telephone and communications cables. For best practice, backfill the trench to approximately 300mm above the service line, lay the tape loosely along the trench length, and complete the final backfill. This ensures excavation equipment encounters the warning tape before reaching the cable.

Who Is This For?

  • Excavation and groundworks teams operating near telecom infrastructure.
  • Utilities and telecommunications contractors.
  • Civils and highways teams marking underground services.
  • Site managers and procurement teams specifying trench safety controls.

Competitive Advantages

This professional-grade warning tape combines clear telecom identification with durable LLDPE construction, making it suitable for long trench runs and repeat excavation cycles where consistent service marking is essential.

Is this tape adhesive?
No. It is a non-adhesive marker tape designed to be laid loosely in trench backfill.

Will it remain legible underground?
Yes. The rot-resistant and acid-resistant LLDPE construction helps maintain visibility long term.
