Deckguard has the highest tested resistance for crack-bridging, having been tested to 40 cycles for 1/8” at -15°F to ensure water-tightness under extreme deck movement. It is the first membrane system to use IR Fingerprinting during manufacture and to provide individual batch IR printouts with each shipment guaranteeing material shipped meets all published test data. This innovative membrane provides maximum protection against stray current, making it ideally suited for use on cantenary and live third rail LRT bridges for protection of embedded steel reinforcement and steel decks.
This spray-on membrane can be applied to 5 mil profiled steel decks without priming, eliminating a time-consuming step and providing faster placement for time-sensitive installations. It is extremely resistant to water vapor transmission and protects against moisture entrapment between Deckguard and deck surfaces that could be susceptible to freeze-thaw degradation.
It can be applied in extreme cold and elevated temperatures exceeding 170°F surpassing the limitation of 104°F of both MMA and Urethane membranes.
Deckguard can be used in conjunction with hot asphalt overlays to provide the best possible protection against penetration of saltwater from winter snow and ice prevention activities. Deckguard Primer will bond with asphalt residue to allow quick installation when time
constraints warrant fast turnaround.
