Key Features
Why Choose This Underground Tape?
Acid/Alkali Resistant PE
First, the tape uses specialized antioxidant additives. It remains intact and legible in the ground for decades, even in acidic or alkaline soil.
Detectable Option Available
Next, detectable tape has an aluminum foil core. Workers can use signal generators to locate buried PVC or fiber lines from the surface.
Built for Infrastructure Safety
APWA Color Compliant
Also, we follow Red for Electric, Blue for Water, Yellow for Gas, Green for Sewer, and Orange for Telecom.
Custom Legends Available
Finally, we print warnings in multiple languages. This meets local municipal codes for international projects.

Storage & Shelf Life
Store rolls in original cartons in a cool warehouse. Avoid prolonged UV exposure before burial. The film remains effective for 36 months.
Field Application Notes
Soil pH and Material Degradation
In industrial areas, soil may be highly acidic or alkaline. Cheap interior-grade PE ribbons will dissolve within months.
Detectable vs. Non-Detectable
Non-detectable tape only works when someone starts digging. Detectable tape has an aluminum foil layer for surface locators.
