Siplast TeraPro Waterproofing

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. Practical applications for the new resin, which included everything from aircraft windshields to dentures, soon followed. The material proved to be exceptionally durable, and the use of PMMA grew rapidly.

Terapro formulations are available for both pedestrian access areas and vehicular traffic applications. To learn more about Terapro PMMA liquid-applied waterproofing.

Terapro is a liquid-applied, layered application consisting of one coat of primer, one or more waterproofing/wearing layers, a hard-wearing surfacing, and a surface finish layer. Reinforced systems for use over occupied spaces include a polyester fleece fabric for additional protection. Each of the liquid-applied layers is comprised of a specially formulated, solvent and VOC-compliant, catalyzed polymethyl methacrylate (PMMA) resin. The completed high mil thickness Terapro application is resilient, monolithic, seamless, durable, and resistant to UV, foot traffic, and numerous environmental contaminants.
