The authors will provide a comprehensive comparison of two technologies, glass flake reinforced epoxy and fiber filled epoxy, specifically for use in severe sewer collection environments on concrete structures. The paper will briefly describe the history of both technologies, how they are manufactured, and their application characteristics. The authors will also detail the advantages of glass flake reinforced epoxies in reduction of permeability, their ability to be used as a resurfacer on degraded concrete structures, their high build properties as well as their increased chemical and flame resistance. The paper will conclude with multiple case history examples of successful applications in severe sewer collection environments where high H2S levels require a coating with extreme performance.
