When refurbishing an old concrete secondary containment wall around a storage tank, what criteria should be used to determine if a crack can be repaired for coating or if the section of the wall should be rebuilt?

From Warren Brand of Chicago Corrosion Group on March 1, 2018:
If the containment area is structurally sound, any crack of any size can be repaired and the wall and area properly overcoated and sealed.

From Brian E Bennett of Bennett Construction & Enterprises, LLC on February 27, 2018:
If a crack is 1/4 inch or less, coat it with a product with elongation, and if larger and dynamic, it needs a little more attention, meaning probably routed out, filled with backer rod and polyurea.

From Larry Muzia of Exceletech Coating & Applications, LLC on February 22, 2018:
It is difficult to properly answer with the limited information in  the question; however, there are many options available, provided a properly informed and trained engineer makes an inspection and determines the cracked area can be repaired. Epoxy injection is one method that is viable, and, sometimes, routing the crack and filling in the space with a repair mortar or epoxy compound can also be a viable method. Of the 3 constants in the Universe, there are death, taxes and concrete cracks!

From Michael Halliwell of Thurber Engineering Ltd. on February 21, 2018:
Unfortunately, I can't be much help in terms of criteria for crack repair regarding coatings. However, any "old" secondary containment showing cracking of a magnitude enough to spark this question probably needs to be evaluated to make sure it will do the job it is supposed to, new coating or not, in the event of a release.
