Corrosion in Steel Frame Buildings can lead to minor displacement of masonry, and opening of joints to larger issues such as cracking of the masonry units, loss of masory pieces, and loss of section.  The damages caused by corrosion can eventually lead to large pieces falling from the building, which has been cause for Facade inspection laws in cities such as New York, Chicago, etc.

Repairing the damages to the masonry and treating the steel frame can be costly.  As corrosion damages accelerate on a building over time, the costs of these repairs increase dramatically.  Often times, removing masonry for a traditional repair can lead to further damages to adjacent masonry, and can also push corrosion cells into other areas of the building. 

By investigating the corrosion condition prior to major damages, preventative long term corrosion treatments can be designed.
