Madewell Products Corporation manufactures mortar and epoxy materials for concrete restoration and protection. These products are commonly used in the sanitary sewer, industrial process, flooring, and aquarium lining markets, as well as others. Our largest product line, the Mainstay Composite Liner, consists of a high strength restoration mortar and an epoxy corrosion barrier coating. These two materials are used to repair and protect concrete and brick structures in sanitary sewer and industrial process markets. The Mainstay Composite Liner was originally developed in 1962 by United States Steel Corporation as a process for lining reinforced concrete pipe. In 1971, U.S. Steel decided to divest its coatings interests, including Mainstay. Soon thereafter, Madewell Products Corporation was established to manufacture Mainstay products. Today, Madewell Products Corp. has expanded its business to include application equipment and products. Madewell Products Corp. manufactures all of its products and equipment at its headquarters in Alpharetta, GA.
