JP Morgan Chase turned to SOPREMA for a permanent solution to several unique waterproofing issues. The answer was a fully reinforced, low odor ALSAN RS 260 LO PMA (polymethacrylate) System with a slip resistant surfacing layer (ALSAN RS 290 Textured Finish) that offers a 20 year guaranteed waterproofing solution.
JP Morgan Chase & Co is a global investment banking and securities firm with corporate headquarters located in New York City. The firm is recognized as one of the “Big Four” banks of the United States with Bank of America, Citigroup and Wells Fargo. The banks location at 4 New York Plaza is a Brutalist design that is quite striking from street level. The building was designed and built in 1969.
The 4 New York Plaza building experienced leakage issues with elevated structural support beams and the concrete roofing deck for years with no clear solution in sight. Until SOPREMA presented the ALSAN RS 260 LO System with a slip resistant surfacing option which provided a low odor, monolithic liquid membrane solution ideal for such challenging structures. SOPREMA’s ALSAN RS System was the ideal choice featuring advanced PMA (polymethacrylate) technology that requires no flames, hot kettles or hazmat restrictions while providing a superior, 20 year guaranteed waterproofing system.
On this job, a liquid system was the only logical choice to waterproof difficult elevated structural columns. With the use of ALSAN RS Fleece, the system becomes a monolithic, 20 year fully reinforced system that completely waterproofs the columns where they enter the brick walls resulting in a dry interior and substantial savings on maintenance. Unlike most unsaturated polyester and urethane systems, the PMA (polymethacrylate) based ALSAN RS System can be installed at temperatures well below freezing and cures in just minutes. The low odor formulation was critical at 4 New York Plaza due to the AC cooling tower present on the roof.
