Product Name

Underground Utility Warning Tape 365m x 100mm – CAUTION GAS MAIN BELOW – Yellow LLDPE

Overview

Designed for high-risk excavation environments, this underground utility warning tape provides a clear visual alert before tools reach buried gas mains. Manufactured from rot-resistant Linear Low-Density Polyethylene (LLDPE), it is laid within trench backfill to help prevent accidental gas strikes, leaks, emergency repairs, and costly site delays across utilities and civil engineering projects.

Key Features & Benefits

  • High-visibility yellow tape with bold “CAUTION GAS MAIN BELOW” legend for instant recognition.
  • Manufactured from Linear Low-Density Polyethylene for long-term underground durability.
  • Rot-resistant and acid-resistant to maintain legibility over time.
  • Non-adhesive design intended for loose placement in trench backfill.
  • Large 365m roll length supports long trench runs with fewer joins.
  • 100mm width ensures strong visibility before excavation reaches the gas main.
  • Helps reduce gas leaks, emergency shutdowns, and reinstatement costs.

Installation & Applications

Suitable for utilities, civils, groundworks, and construction projects involving buried gas mains. For best practice, backfill the trench to approximately 300mm above the service line, lay the tape loosely along the trench length, then complete final backfilling. This ensures excavation tools encounter the tape first, providing a clear warning before contact with the pipe.

Who Is This For?

  • Groundworks crews operating near buried gas services.
  • Utilities contractors installing or maintaining gas networks.
  • Civil engineering teams managing trench safety on live sites.
  • Site supervisors and procurement teams specifying risk controls.

Competitive Advantages

This professional-grade gas warning tape combines high visibility, durable LLDPE construction, and industry-recognised colour coding to reduce excavation risk. Its non-adhesive design enables fast deployment along long trench runs, helping contractors maintain safety and control project downtime.

Frequently Asked Questions

What is underground utility warning tape used for?
It is used to visually mark the route of buried gas mains so excavators receive a warning before reaching the service.

How deep should gas warning tape be installed?
Best practice is approximately 300mm above the gas pipe so the tape is encountered first during excavation.

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

Will the tape last underground long term?
Yes. The LLDPE construction is rot-resistant and acid-resistant for long-term underground use.

What other utility variants are available?
The range typically includes versions for water, electric, fibre optic, telecoms, sewer, street lighting, and traffic signals.
