Inspection, Repair & Maintenance Programs for Chimneys & Stacks
Chimneys and stacks are vital components of power production and industrial facilities. Their unique operating conditions subject them to a number of different factors that can be detrimental to their integrity including exhaust fumes and gases, fuel ashes, condensation, rain, thermal variations, UV exposure, lightning, atmospheric CO², wind and ground stability. These factors can lead to deterioration of both external and internal components.
