TRIALA manufacture underground warning tapes that are designed to provide a clear visual indication of buried utility lines, helping to prevent accidental damage during excavation projects. These tapes are made from durable materials that can withstand the harsh underground environment, ensuring long-lasting visibility and safety.

Polyethylene underground warning tape is used to alert workers and prevent accidental damage to buried utilities. It is typically placed above gas, water, or electrical lines to signal their presence during excavation. This visual warning helps ensure the safety of construction and maintenance crews.

Non-detectable underground warning tape offers advantages such as cost-effectiveness and ease of installation compared to detectable warning tape. While it does not contain metal for detection, it serves as a visual deterrent during excavation to prevent accidental damage to buried utilities. Additionally, non-detectable tape is often more resistant to corrosion and environmental factors, ensuring long-lasting visibility underground.
