Evaluation of a Procedure for Encapsulation and Epoxy Injection of Corroding Reinforced Concrete Structures

A procedure involving encapsulation and epoxy injection for extending the service life of corroding reinforced concrete structures was studied. Specimens that were exposed to a corrosive environment for four and a half years were used. Corrosion activity in the specimens was well-documented. The specimens repaired using the encapsulation procedure and companion unrepaired specimens were exposed to a corrosive environment for one year and were monitored. At the end of the study the specimens were opened to examine the condition of reinforcing bars and concrete inside the specimens.
