High-Visibility Caution Warning Tape for Safety Marking
Accidental strikes on unidentified underground utilities can cause service disruptions, equipment damage, and safety hazards at construction and excavation sites. Caution warning tape, installed above buried pipes, cables, and utility lines, alerts excavation crews before they reach critical assets, providing an essential layer of protection for electrical, water, gas, and telecom infrastructure.
Durable caution warning tape is ideal for construction, electrical, water, and telecom projects, ensuring clear underground marking and improved site safety. The full corys packaging range includes detectable and non-detectable underground warning tapes, construction barricade tapes, and packaging tapes, all aligned with APWA standard colour coding for various utility types and site applications.
At Dutco Tennant LLC, certified warning tape and utility marking tape products meet the rigorous demands of construction, civil infrastructure, and utility projects across the UAE and GCC, supporting safe excavation and asset protection on high-risk sites.
Visual Warning and Electronic Detection Above Every Buried Asset
- Detectable warning tape contains a solid aluminium foil core encased between reverse-printed film and virgin polyethylene, allowing electronic location from the surface using a non-ferrous metal detector
- Non detectable warning tape uses acid and alkali-resistant low-density polyethylene construction, providing a durable visual warning to excavation crews upon uncovering during digging
- APWA standard colour coding identifies utility type at a glance — red for electrical, blue for water, yellow for gas, orange for telecom, and green for sewer across all tape variants
- Printed warning legends on all tape variants identify the buried utility type and alert excavators before further digging causes damage to the asset below
- Packaging tapes and caution tape roll configurations available in standard and custom lengths to suit varying trench runs and site requirements

Standout Features & Benefits
Clear Identification at Every Utility Type
- APWA standard colour coding across all variants ensures excavation crews immediately identify the buried utility type upon uncovering the tape
- Printed warning legends identify utility type and alert crews to the buried asset below without any additional signage requirement on site
- Underground marking tape placed at the correct depth above the utility provides advance warning before excavation equipment reaches the buried asset
Durable in Aggressive Ground Conditions
- Polyethylene and laminated film construction resists soil acids, alkalis, moisture, and chemical degradation across extended underground service life
- Reverse-printed and encased legends maintain legibility across the full buried service life without ink rub-off or surface degradation
- Warning caution tape above-ground variants resist UV exposure, weather, and physical contact across outdoor construction site conditions
Electronic Location Before Excavation
- Solid aluminium foil core in detectable underground warning tape allows precise surface location using non-ferrous metal locators without physical excavation

FAQ
What is the difference between detectable and non-detectable warning tape?
Detectable tape contains an aluminium foil core that can be located electronically from the surface using a non-ferrous metal detector. Non-detectable tape is polyethylene only and provides a visual warning when uncovered during excavation.
At what depth should underground warning tape be buried?
Tape should be buried a specified distance above the utility line, typically between the service and finished surface level. Exact depth requirements should be confirmed against local utility authority and project specifications.
What colour coding standard is used across the warning tape range?
All tapes are produced to APWA uniform colour code standards — red for electrical, blue for water, yellow for gas, orange for telecom, and green for sewer across both detectable and non-detectable variants.
Can custom print legends be applied to warning tapes?
Yes, custom print legends including utility type, contractor name, project identification, and contact details are available across detectable and non-detectable tape variants in standard and non-standard widths.
Is detectable warning tape a replacement for tracer wire?
No, detectable tape and tracer wire serve different purposes. Detectable tape provides a physical and electronic warning layer above the utility. Tracer wire runs alongside the buried asset for precise continuous location. Both are often specified together on critical utility routes.
Are warning tapes resistant to soil chemicals and moisture?
Yes, polyethylene and laminated film construction resists soil acids, alkalis, and moisture across extended underground service life in varying ground conditions common across GCC construction environments.
