Utilizing a specialized fleet of drones, we can perform Class I inspections on your chimney or tower. Although Class I inspections are usually performed only on the exterior while the unit is in operation we can also conduct a visual inspection of the interior during planned outages. We cannot however perform liner materials testing and therefore are not a complete replacement for Class II inspections.

Industrial Chimneys (smokestacks) and Cooling Towers, require timely inspections for their good working order and to identify issues before they cause a shut down. Repair activities involving significant and unplanned expenditure are often triggered by conditions that may have been mitigated if inspection and maintenance had been performed in a timely manner.
Each chimney or tower is a unique structure, subject to both aggressive operating and natural environments, and degradation over time. Such degradation may be managed via a prudent inspection program followed by maintenance work on any equipment or structure determined to be in need of attention.
According to the American Society of Civil Engineers there are three levels or classes of inspections performed on chimneys.
Class I inspections are routine inspections that should be performed at regular intervals of between 6 and 24 months. A Class I inspection is primarily a visual inspection.
Class III inspections are not routine. They are performed only when significant degradation of any structural component has occurred, as indicated by the results of Class I or II inspections, or when the chimney has experienced an unusual event such as a natural disaster or particularly destructive weather.
Class II inspections should be performed at regular intervals in the range 2 to 5 years, and alternated with Class I inspections. A Class II inspection will be performed with the chimney off-line, and will include all of the work performed for the Class I inspection, plus a full-height interior inspection. A Class II inspection must include some form of hands on nondestructive testing of liner materials.
