Underground Utility Signs, Labels and Markers

Clearly marking underground utility lines can help avoid excavation accidents that lead to deaths, injuries, service interruptions, environmental damage and liability. Here you'll find pipeline and underground utility signs, labels and marker posts for gas pipelines, water and sewer lines, petroleum pipelines, buried electric cables and more.

Our utility marking posts can also be used for 9-1-1 emergency markers or anywhere a strong, flexible marking post is needed. For more information on utility marking, see our resource links below.
