UniMark System is a durable underground utility marker that is placed directly above the pipeline and related facilities! It complies with American Public Works Association (APWA) uniform color-code for Gas, Electrical, Communications, Water, Wastewater and Water Reclamation standards.
This marking method supports the One Call System International (OCSI), Common Ground Alliance Best Practices (CGA), Pipeline and Hazardous Materials Safety Administration (PHMSA) and the USDOT Office of Pipeline Safety while focusing on Third Party Damage Prevention.
UniMark’s marking symbols assist with safety, education, training, public awareness and risk management. They are used by pipeline companies for their operations and First Responder personnel to permanently recognize key underground facilities during an excavation emergency.
The resilient colors of the heat-fused surface-mounted markers are bright, concise and will illuminate day and night for years to come.
Marking underground pipelines with UniMark can be accomplished while on routine facility inspection and maintenance, field locating surveys and "811-DIG SAFELY ALERTS".
