Liquid-applied solutions for pedestrian and vehicular areas
One of the most successful commercial product innovations of the last century occurred in the 1930s when polymethyl methacrylate resins, commonly known as PMMA, were first synthesized. But in spite of its exceptional performance and rapidly growing use, the material was too rigid for use in waterproofing applications – until the 1970s. That's when a PMMA formulation was developed that, once cured, was resilient rather than rigid. Today, Siplast Terapro Waterproofing and Surfacing Systems offer all the benefits of PMMA technology in products for plaza deck, balcony, concrete protection, and vehicular traffic applications. The science of PMMA provides exceptional performance advantages and significantly faster cure times than polyurethane and polyester systems.
