▪ What Elements make up a good corrosion
management program?
Corrosion 101 - Review
▪Building materials are not found – their made
Corrosion 101 - Review
Corrosion 101 - Review
▪As metals are made, we strip off O2 in a low oxygen environment
Corrosion 101 - Review
▪On a microscopic level, as the materials cool, the surface exhibits differential charges
Corrosion 101 - Review
▪So how do we protect atmospheric Structures?
Corrosion 101 - Review
▪We can change materials

For brevity, lets talk about 1
element:
Coatings Condition Assessment

If the coating life can be extended
by overcoating, over time, cost of
coatings maintenance can be
reduced
Coating Condition Assessments
Coatings Surveys – quantifies the “what” and “when”
items needed to be budgeted –
Includes:
▪Coatings
▪Concrete
▪Joint Sealants
▪Composites
▪Used as an element of Warranty Inspections

Summary
▪ A good corrosion management program is
made up of multiple elements
▪ Each element cannot be ignored or
discounted
▪ Implementation of the elements reduces
cost over time
