Above Ground Markers

Protect and accurately identify underground infrastructure with professionally installed Above Ground Markers (AGMs). We utilize Comtel Sentinel AGM boxes to provide durable, highly visible reference points for buried utilities, telecommunications networks, fiber optic cables, pipelines, and other critical underground assets.

Above Ground Markers serve as permanent surface indicators that help utility owners, contractors, and maintenance personnel quickly locate underground facilities, reducing the risk of accidental damage during excavation and construction activities. Each marker can be customized with utility-specific information, warning messages, contact details, and asset identification numbers for efficient asset management and emergency response.

Our AGM installation services support new utility construction, network expansions, utility relocations, and long-term asset protection programs. Comtel Sentinel AGM boxes are engineered for durability and visibility, providing reliable performance in a wide range of environmental conditions. Their rugged construction helps ensure critical utility information remains accessible for years to come.

By combining precise utility locating practices with strategically placed above ground markers, we help create a comprehensive utility tracking system that improves safety, streamlines maintenance operations, and supports regulatory compliance. Whether for telecommunications, power, water, gas, or private utility networks, our AGM installations provide a dependable solution for identifying and protecting underground infrastructure.
