Underwater pile repair using FRP - state of the art

Fiber reinforced polymers (FRPs) were first used for repairing corrosion damage in a prestressed concrete bridge spanning the Bay of Tokyo, Japan in the 1970’s. Twenty years later when the bridge was replaced and selected girders examined it was discovered that FRP had prevented further intrusion of chlorides. Subsequently, research studies were undertaken to quantify the benefits of using FRP in chloride-induced corrosion repair. This paper provides an overview of the findings from long term laboratory studies and several field demonstration projects undertaken by the University of South Florida over the past decade to explore the use of FRP for repairing corroding piles in tidal waters. The findings are presented in the form of answers to questions that are of interest to highway authorities considering using FRP for corrosion repair.
