Chimney & Stack Inspections & Repairs


Don't let your production or facility come to a standstill due to a chimney system failure. Having your industrial chimney or smokestack regularly inspected and monitored will help identify potential problems and fix them before they turn into expensive unplanned outages or structural failures. Industrial Access provides complete industrial chimney repairs, inspections and structural testing for chimney and stack building materials, such as concrete, brick, steel, & FRP (fibre reinforced polymer). We are prepared to assess breaching ducts, tanks, silos, and other industrial structures. We provide thorough smoke stack inspection services for power plant stacks, boiler stacks, manufacturing stacks, and a range of other smoke stack structures. Stack cleaning is also available as part of a regular maintenance plan.

There are three classes of inspections that we can perform on industrial chimneys & smokestacks:

Class I Inspections - Class I is a visual inspection that can be performed while the chimney or smoke stack is operating. A chimney technician first inspects the structure using binoculars from ground level, then performs a close-up visual inspection from access ladders, platforms or other accessible vantage points. With the stack online, we can use Infrared Thermography to check for "hot spots" that could indicate liner damage or flue gas leakage. Generally, Class I Inspections are conducted at least once a year to help identify potential threats that could turn into expensive problems.

Class II Inspections - This class of inspection is performed with the chimney or smokestack off-line. Using our rope access techniques we are able to take a close look at the inside and the outside of the structure. Our crew installs the required rigging to the top of the stack. Chimney technicians then descend down the entire elevation of the stack, both outside and inside, to note & document the structure's current condition and any abnormalities, damage, or potential hazards. A thorough inspection of the liner and annulus is performed. Depending on the structure's condition, a Class II inspection may also include:

Class III Inspections - Class III Inspections are generally associated with unique circumstances that require an in-depth and expansive examination of the smoke stack for safety and stability. If your industrial chimney, power plant stack, boiler stack, or other smoke stack structure was damaged due to severe weather, earthquakes, explosions, overheating, or other natural disasters, a Class III Inspection should be performed immediately to ensure that the structure does not pose any safety hazards. A Class III inspection should also be performed before any significant structural modifications to a chimney or liner, such as increasing height or installing additional platforms or breechings. All aspects of the Class II Inspection are performed, plus physical samples and tests are taken, analysed, and included in the engineering review.

We can also perform a hot camera inspection that allows us to inspect a chimney or stack while it is online*


Our Inspection Services include:

During an inspection, we can also perform Petrographic testing which examines numerous characteristics of concrete to determine if there is a problem in the condition of the structure. It can identify the underlying cause or reason a concrete structure has failed.
