Underground Utility Warning Tape 365m x 100mm – CAUTION FIBRE OPTIC CABLES – Green LLDPE

Product Name

Underground Utility Warning Tape 365m x 100mm – CAUTION FIBRE OPTIC CABLES – Green LLDPE

Overview

Designed for professional excavation environments, this underground utility warning tape provides a clear visual alert before tools reach buried fibre optic cables. Manufactured from rot-resistant Linear Low-Density Polyethylene (LLDPE), it is laid in trench backfill to help prevent accidental cable strikes, service outages, and costly repair works across utilities, civils, and highways projects.

Key Features & Benefits

• High-visibility green tape with bold “CAUTION FIBRE OPTIC CABLES” legend for immediate 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 service.
• Helps reduce fibre network damage, outages, and reinstatement costs.

Installation & Applications

Suitable for utilities, telecoms, civils, highways, and groundworks projects involving fibre optic installations. 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 cable.

Who Is This For?

• Telecoms contractors installing fibre optic networks.
• Civil engineering and groundworks teams working in utility corridors.
• Highways and infrastructure maintenance crews.
• Site managers and procurement teams specifying trench safety controls.

Competitive Advantages

Unlike lightweight tapes, this professional-grade marker is engineered for long trench runs and harsh ground conditions. Its combination of material durability, clear warning legend, and industry-standard colour coding supports safer excavation and reduced lifecycle risk on fibre infrastructure projects.

Frequently Asked Questions

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

How deep should fibre optic warning tape be installed?
Best practice is approximately 300mm above the cable so the tape is encountered before the service 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, gas, electric, telecoms, sewer, street lighting, and traffic signals.
