Our story is one of uncompromising quality, innovation, partnership, and commitment to our customers and their communities.
Take a look at what has made that story possible.
Jacob K. Javits Convention Center
New York, NY -- In addition to addressing numerous leaks, Siplast helped establish the Jacob K. Javits Center as an international model of sustainable best practices with an extensive green roof system. So successfully that the 6.75 acres of vegetation -- the second-largest in the country -- are providing a wildlife habitat.
The Century Project at Space Needle
Seattle, WA -- Siplast helped update the observation deck of Seattle's beloved Space Needle using our fast-curing PMMA liquid-applied Terapro Waterproofing and Surfacing System. As well as making scheduling work around the famously rainy local climate possible, the fast cure (rain proof in 25 minutes, next-coat-ready in 45 minutes) and phased application allowed tourists to visit daily without interruption.
New Orleans Sports Arena
New Orleans, LA -- Veral – one of Siplast's signature systems – helped actualize architects’ high-concept vision for the roof of this landmark facility, and delivered high performance in tough environmental conditions as well as visual appeal.
United Nations General Assembly
