Product Name

Underground Utility Warning Tape (365m x 100mm) - Heavy Duty Marker for Electric, Gas & Water

Overview

Prevent costly utility strikes and strengthen excavation safety with heavy duty 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, helping prevent life-threatening hits on high-voltage cables and dangerous gas line strikes. Supplied in high-visibility 365m rolls with a 100mm width, it delivers long trench coverage and clear marking before buckets or shovels reach the buried service.

Key Features & Benefits

• Prevents costly accidents by warning excavators before contact with buried cables and pipes.
• Standard 365m x 100mm roll format supports maximum visibility and trench coverage.
• Rot-resistant LLDPE construction helps keep the tape intact and legible underground for years.
• Non-adhesive marker tape designed to be laid loosely in trench backfill, not stuck to services.
• Industry-standard colour coded variants help identify key utilities quickly on site.
• Acts as a vital visual barrier when placed approx. 300mm above the service line.

Installation & Applications

Designed for use in excavation, utilities, civils, highways, and groundworks projects to mark the location of buried services such as electricity, gas, water, telecoms, fibre optics, sewer, street lighting, and traffic signals. For best practice, do not place the tape directly on top of the pipe or 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 damage occurs.

Who Is This For?

• Excavation and groundworks teams working near buried services.
• Utilities contractors installing or maintaining cable and pipe networks.
• Civils and highways teams marking services for safer future excavation.
• Site supervisors and procurement teams specifying trench safety controls.

Competitive Advantages

This heavy duty underground warning tape combines high visibility, rot-resistant LLDPE durability, and a standard 365m x 100mm format to help reduce the risk of accidental utility strikes. Its non-adhesive design makes it easy to deploy along long trench runs, while the industry-standard colour coding supports clear identification of different service types on busy sites.
