Underground Warning Tapes Page 2

Underground Warning Tapes from eSafety Supplies help contractors, utilities and councils mark the location of buried services before excavation or trenching work begins. The range covers both detectable and non-detectable mains marker tape for water, sewer, electrical, gas, communications, fibre optic, irrigation, fire fighting, stormwater and recycled/reclaimed water mains, along with electrical cable hard cover for extra physical protection.

These tapes are laid above buried pipes and cables during backfilling so that anyone digging in the area gets an early visual (or, for detectable tapes, electronic) warning before they reach the service below.

What's included:

• Detectable mains marker tape: tapes with an integrated conductive element for water, electrical, communications, gas, fibre optic, irrigation, fire fighting and stormwater mains, locatable with a cable/pipe locator.
• Standard (non-detectable) mains marker tape: printed warning tape for water, electrical, gas, sewer and railway signalling cable at 150mm x 500m rolls.
• Combined service tape: a 3-way mains marker tape covering gas, electricity and communications in one product.
• Electrical cable hard cover: double-sided rigid cover for extra mechanical protection over buried electrical cable.

Use cases:

• Civil and utility contractors: marking newly laid water, sewer, gas and electrical mains during backfilling.
• Councils and asset owners: maintaining a visible and detectable warning layer over public infrastructure to reduce third-party strike risk.
• Telco and NBN contractors: identifying buried communications and fibre optic cable routes.

FAQs

What's the difference between detectable and non-detectable tape?
Detectable tape has an embedded conductive foil or wire that can be picked up by an underground service locator, even after the tape itself has degraded or is buried deeper than expected. Non-detectable tape provides a visual warning only, for anyone digging by hand or machine.

How deep should underground warning tape be laid?
Placement depth varies by service type, authority and jurisdiction, but tape is typically laid a set distance above the pipe or cable, allowing a warning before excavation equipment reaches the service. Check the requirements of the relevant asset owner or utility authority, along with AS/NZS 2648.1 for underground marking of pipes and cables.

Which tape colour and wording should I use for gas versus water mains?
Colours and wording follow common convention (for example yellow for gas, and colour-coded printing for water, electrical, communications and sewer), matching what's printed on each product listing so crews can identify the service at a glance.

Can I use the same tape for a fire main or an irrigation line?
Yes, the range includes tape specifically printed and worded for fire fighting mains and irrigation lines, in addition to the more common water, gas, electrical and communications options.
