NASA’s mission is to “pioneer the future in space exploration, scientific discovery, and aeronautics research.” The facilities and equipment necessary to achieve this mission are critical and require ultimate protection from the elements. 

In order to explore our universe, large rockets are required to propel shuttles and satellites into space. The engines on these rockets are tested prior to use to ensure they are safe and will perform properly. At Stennis Space Center, NASA tests these rocket engines by propping them up against giant stands. After they are stood up and secured, the literal term “blast-off” is appropriate. The top-level roofs on these test stands, which also serve as observation decks for high-level guests, have been a source of problematic leaks into the sensitive rooms below.

This particular test stand roof was an excellent candidate for a liquid membrane recover, instead of a disruptive and costly tear-off that would expose the facility to the elements. The steel roof had been coated with a urethane system previously. NASA sought to avoid any toxic, flammable, or solvent-based coatings. TritoFlex 2K fit the bill. It would provide great adhesion to the existing substrate while providing an industrial-grade synthetic rubber membrane with a completely non-toxic, non-intrusive application.

The TritoFlex 2K liquid rubber membrane was installed in a single coat at 80 dry mils to the entire existing substrate, creating a monolithic seal and increased durability to foot traffic and ponding water resistance. The membrane was then top coated with the one coat, instant-set TritoCryl 2K white coating to finish off the roof with a slip-resistant surface and reflective benefits in the hot Mississippi summers.

Triton provides stronger, safer, and smarter alternatives to traditional roofing and waterproofing technologies. We specialize in providing our products to help protect industrial and institutional facilities like NASA around the world.
