The purpose of this paper is to provide the history and technological developments of liquid epoxy polymer concrete formulated in the United States as a coating for the protection of buried pipelines. Throughout this paper, liquid epoxy polymer concrete refers to one specific product line and is not necessarily representative of all liquid epoxy polymer concrete. This paper will describe how the product is used for both new pipeline construction and for the rehabilitation of existing lines. Technical data will
be presented to illustrate the coating's performance characteristics in terms of corrosion and mechanical protection to the steel pipeline. Case histories are included to demonstrate recent experiences with the
liquid epoxy polymer concrete.
