▪ 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

▪Or we use protective coatings

For brevity, lets talk about 1

element:

Coatings Condition Assessment

Coating Condition Assessments

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
