This is the detectable version of Hamilton Gas Products' underground marker tape. The key difference from the non-detectable 365m tape is two stainless steel wires embedded in the mesh, which allow a standard cable or pipe locator — the same type used to locate buried cables and pipes before excavation — to find and trace the tape from the surface, even after burial and even where original excavation records are lost or unavailable.
When contractors scan the ground before digging on a future project, the embedded wires signal the presence of a gas main below, before any excavation reaches the tape itself. It's printed with a continuous "CAUTION BURIED GAS MAIN" warning in black on yellow, and made from heavy-duty, rot-resistant polyethylene mesh designed to remain intact and detectable for the life of the buried installation.
At 200mm wide, it's wider than the non-detectable 365m version, giving a broader visible warning band in the trench once uncovered. The 100m roll length is shorter than the non-detectable tape — detectable tape carries a higher cost, so it's typically specified for the most critical runs where surface tracing capability justifies the extra expense. As with the non-detectable version, it should be laid approximately 300mm above the top of the pipe during backfill, per NJUG guidance.
The embedded stainless steel tracer wires give this tape a genuine advantage over the non-detectable version: it can be located from the surface before a spade or digger ever touches the ground, which matters on critical gas main routes or where excavation records are incomplete. Stainless steel resists corrosion over a long underground service life, and at 200mm wide it gives a broader visible band than the standard tape once uncovered. For road crossings, footway crossings and other high-risk locations, that added traceability can be the deciding factor over the lower-cost non-detectable option.
