Why it works

Why lay this warning tape

Highly visible

Bright blue film with bold black print stands out clearly when a trench is opened, giving diggers immediate warning.

Clear drain identification

Printed CAUTION WATER DRAIN BELOW along the full length leaves no doubt about what lies beneath.

Colour-coded for water services

Blue is the colour used across the utilities sector for water-related routes, so crews can identify the service at a glance.

Full-length roll

Each roll runs 365m, enough to mark long drain runs without joining multiple rolls together.

Frequently asked questions

What does the tape actually say?

It's printed "CAUTION WATER DRAIN BELOW" in black along the full length of the blue film, repeated so the warning is visible from any angle once a trench is opened.

How is this different to a detectable tape or mesh?

This is a printed warning tape only - it has no metal trace element, so it will not show up on a cable or pipe locator. For a detectable option, look at our detectable underground tape or detectable mesh ranges.

At what depth should it be laid?

Lay it in the backfill above the drain, below the final surface layer, so it's the first thing uncovered if the trench is reopened. Follow your project's or the water authority's own depth specification.

Why is the tape blue?

Blue is the colour used across the water and drainage sector for underground service marking. We stock this same tape printed for other services in their own standard colours.

Does one roll cover a full run, or will I need to join rolls?

Each roll is 365m, which covers most drain runs from a single length without a join.

What is the tape made from?

LDPE (low-density polyethylene) film - a lightweight, flexible plastic tape, not a fabric or foil.

Can it be lifted and reused?

No, it's intended to be laid once in the backfill and remain buried as a permanent marker.
