LEESPORT, Pa. — The largest and most complex re-roofing project in Chicago during the past 10 years capped off in late September with the installation of 10.3 acres of Flex Elvaloy® KEE thermoplastic membrane atop the Jardine Water Filtration Plant on Lake Michigan next to the Navy Pier.

Replacing a 50-year-old graveled coal tar pitch roof, the hot-air welded membrane is designed to be impervious to the city’s wind and weather extremes, chemicals, UV light and acidic bird deposits. Built on rubble from the Great Chicago Fire of 1871, the 50-year-old Jardine plant processes almost one billion gallons of potable water per day — more than any other purification system in the world — to five million consumers throughout Chicago and surrounding communities.
