The repair of concrete port and harbor structures is one element of a larger problem in the United States and world wide. That is the general decay of infrastructure as a result of aging, design and construction deficiencies, and a scarcity of funds for maintenance. This report examines the concrete port and harbor structure portion of that crumbling infrastructure in an effort to understand the ways in which deterioration occurs and how it can be prevented, arrested or repaired. Concrete has many properties which makes it suitable and desirable for use in the marine environment. Quality concrete can be produced which has long-term strength gain, low permeability, self healing on cracking and self protection. Concrete can be cast in place or prefabricated and installed either onshore or offshore. In the following sections of this report, we characterize the marine environment for concrete port and harbor structures, review causes of deterioration, discuss methods for assessing deteriorated structures, and review repair methods currently in use.
