Tank Inspection by TMI Coatings, Inc.


Corrosion may set in slowly, but it requires knowledge and maintenance to keep a structure standing, which is why a tank inspection is necessary. A historic, 100-year-old water tower in Elk River, Minnesota is a perfect example of this. This century old water tower built up a considerable amount of corrosion in its four legs since 1920. To preserve this historical piece of infrastructure, the city turned to TMI Coatings, Inc. (TMI).

Our skilled staff is currently assessing the condition of the four legs and their reinforcing plates supporting the water tower. TMI’s strengths lie in our ability to adapt to any condition or structure and take the correct actions. We specialize in meeting our customers’ needs by completing work safely, in a quality matter, and on time. 

With experienced NACE International coating inspectors and American Welding Society certified welding inspectors on-staff, TMI can complete inspections and evaluations of complex structures to assist with longevity and maintenance in addition to the ability to restore these structures.


• TMI completed a field evaluation/inspection of each tower leg including gusset plates, reinforcing plates, and lattice bars to observe for areas demonstrating deformation and/or failure.
• Under direction of the engineer, TMI removed a total of four (4) steel coupons for sampling from the tower base plates and reinforcing plates.
• TMI provided written identification, after the tank inspection, of conditions and provided recommendations for repairs after field inspection in compliance with AWWA guidelines.


This structure, as with many other structures, may continue to stand for years to come due to the knowledge and maintenance expertise TMI offers.

With over 35 years of experience with painting and restoration, TMI Coatings has the expertise needed for evaluating and restoring any steel or concrete structure. Contact us today at 651-452-6100 for your free, no obligation quote.
