This paper presents the findings of a Department of Defense Technology Demonstration project,
Integrated Concrete Pier Piling Repair and Corrosion Protection System. Reinforced concrete pilings
for Piers F12/13 in Pearl Harbor, Hawaii have suffered from significant corrosion of the steel reinforcing
bar (rebar) resulting in the loss of load handling capacity due to spalling of the concrete that resulted
from the corrosion of the rebar. This project demonstrated an integrated concrete pile repair and
corrosion protection system that would reportedly increase the service life of a pier to 20 years in
contrast to only six to seven years if the pier pilings containing high chloride levels are only patched.
