Long term durability of FRP-concrete bond and its constituent materials under the influence of continuous moisture was investigated by an experimental study. The results obtained from both material and bond test revealed excellent water resistant performance even after a year of continuous exposure in water. The only signs of deterioration due to water were observed at the failed surfaces. The failure shifted more towards primer-concrete interface from concrete cohesion failure with increase after immersion.
