Founded by C. Fred Sauereisen in 1899, this third-generation family company manufactures protective linings, coatings, ceramic compounds and related materials for demanding industrial environments. Its roots in specialty cement began with a high-temperature adhesive developed by a self-taught ceramist who worked with George Westinghouse on an early porcelain insulator. Today, Sauereisen is particularly associated with corrosion protection for wastewater and power infrastructure, including its SewerGard® 210 lining system.
