Water Mains Detection Warning Mesh - Pack of 120 Rolls

This underground service detection mesh is a critical safety tool used to identify and protect water mains during excavation. Designed to be buried above pipework or utility lines, it provides a visible and detectable layer that prevents accidental strikes or service disruption during site operations. Its integration with cable location tools ensures buried infrastructure can be precisely mapped before digging begins.

The mesh is produced from highly visible blue polyethylene, clearly signalling the presence of water mains to excavators and engineers. More than just a warning, the product includes a detectable tracer wire that allows it to be traced from the surface using cable detection equipment. This makes it particularly suitable for high-traffic or urban sites where detailed utility maps may be unavailable or outdated.

Its resistance to chemical exposure, including alkaline and acidic soil conditions, means it can be used reliably in a wide range of ground types without degradation. This feature makes the mesh suitable for installation across diverse UK soil zones including clay, sand, chalk and mixed fill environments.

Compliant with ENA TS 12-23 and EN 12613:2009 standards, the mesh meets the specification requirements of many major utility operators. It can be specified as part of planned utility installations or as a retrofit safety enhancement for service upgrades and repairs.

Each roll is 100m long and 200mm wide, offering extensive linear coverage. Lightweight and flexible, the mesh is easy to roll out and secure into trench sections. It can be installed by a single worker without the need for mechanical handling equipment, helping reduce installation costs and timescales.

This product is frequently used in highway reinstatement works, water infrastructure projects, civil engineering trenching and site maintenance. Its role is not only protective but also preventative, offering visual and locatable cues that reduce the likelihood of delays or fines resulting from accidental utility damage.

Unlike traditional marker tapes that rely solely on visual identification, this mesh enhances operational safety by enabling location before visual access is available. Its dual-detection capability makes it a trusted solution for modern site safety management and excavation planning.

When paired with HERMEQ’s wider selection of Underground Service Protection products, this mesh helps form a complete site safety strategy. It’s an efficient, standards-compliant option for protecting critical water infrastructure on every kind of construction site.

Is this mesh suitable for all soil conditions?
This underground service warning mesh is designed to perform in most common UK soil types including acidic and alkaline conditions, ensuring broad site compatibility.

What standard does this tracer mesh meet?
It complies with ENA TS 12-23 and EN 12613:2009 standards, making it suitable for water mains identification and use in regulated underground service applications.

Can it be used for other underground services?
While this mesh is colour-coded for water mains, similar variants exist for gas, electricity, and telecommunications. Always match the mesh type with the underground service for best results.

How is the mesh located after installation?
The built-in tracer wire allows detection tools to accurately locate it from the surface, making it safer and faster to identify buried utilities prior to excavation.
