Underground Utility Warning Tape 365m x 100mm - Caution Electric Cable Below - Yellow LLDPE

Product Name

Underground Utility Warning Tape 365m x 100mm - Caution Electric Cable Below - Yellow LLDPE

Overview

Prevent dangerous electrical cable strikes and reduce the risk of outages, repairs, and site delays with Underground Utility Warning Tape. Manufactured from rot-resistant Linear Low-Density Polyethylene (LLDPE), this non-adhesive marker tape provides a clear visual warning to excavators before tools reach the buried service. Supplied as a large 365m roll with a 100mm width, it delivers high visibility and long trench coverage for utilities, civils, highways, and groundworks projects.

Key Features & Benefits

• High-visibility yellow tape with “CAUTION ELECTRIC CABLE BELOW” legend to warn groundworkers instantly.
• Helps prevent life-threatening electrical strikes and costly utility damage during excavation.
• Standard 365m x 100mm roll format supports maximum trench coverage and easy deployment on long runs.
• Rot-resistant and acid-resistant LLDPE construction helps keep the message intact and legible underground.
• Non-adhesive design made for trench backfill — laid loosely, not stuck to the cable.
• Acts as a critical visual barrier when installed approx. 300mm above the buried service line.

Installation & Applications

Designed for excavation, utilities, civils, highways, and groundworks projects where electrical cables are installed in trenches. For best practice, do not place the tape directly on top of the cable. Backfill the trench to approximately 300mm above the service line, then lay the tape loosely along the trench length before completing the final backfill to ground level. This ensures future excavation tools hit the tape first, providing a critical warning to stop digging before the cable is damaged.

Who Is This For?

• Excavation and groundworks crews working near buried electrical services.
• Utilities contractors installing, repairing, or maintaining cable networks.
• Civils and highways teams needing long-run service marking for safer future excavation.
• Site supervisors and procurement teams specifying trench safety controls and clear service ID.

Competitive Advantages

This professional-grade underground warning tape combines high visibility, rot-resistant LLDPE durability, and a standard 365m x 100mm format to help reduce the risk of accidental cable strikes. Its non-adhesive design makes it fast to deploy along long trench runs, while the bold warning legend provides immediate clarity for groundworkers during future excavation.

Frequently Asked Questions

What is underground utility warning tape used for? It is used to mark the route of buried electrical cables so excavators get a clear visual warning before digging reaches the service, helping prevent dangerous and costly utility strikes.

How deep should warning tape be laid in the trench? Best practice is to place it approximately 300mm above the cable so excavation tools encounter the tape first, providing a warning to stop digging before the service is hit.

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

Will it last underground long term? Yes. It is manufactured from rot-resistant and acid-resistant LLDPE to help keep the tape intact and legible underground for long-term service marking.

Should the tape be placed directly on the cable? No. The tape should be installed above the service line (around 300mm) so it is encountered first during future excavation, giving a warning before contact with the cable.

What other utility variants are available? This tape is part of a wider underground utility marking range, typically including variants for water, gas, telecoms, fibre optic, sewer, street lighting, and traffic signals using industry-standard colour coding.
