BAYER HIGHLIGHTS THICK FILM COATINGS THAT WATERPROOF AND PROTECT ROADS AND BRIDGES AT WORLD OF CONCRETE
It was Baytec’s outstanding combination of physical and chemical properties, as well as a 30-plus-year track record of service in demanding environments around the world, that sealed the deal for this demanding application. “Thousands of commuters rely on these rail bridges each day, so it was imperitive that this bridge rehabilitation project was done right the first time,” said Robert Torielli, president, PIM Corporation, the subcontractor responsible for the waterproofing of the rail bridge decks. “Bayer’s Baytec SPR technology possesses the thermal, abrasion, chemical, water and weather resistance required to provide long-lasting protection for these bridge decks.” Bayer will highlight its thick film coating applications for a variety of industrial applications – including the protection of roads and bridges – at its booth (S11541) at World of Concrete, held Jan. 18-21, 2005, in Las Vegas. Wear and Tear, Mother Nature Take a Toll Increased traffic volume and climatic conditions take their toll on roads and bridges. For example, exhaust gases and the increased use of de-icing salts can damage road surfaces, which in turn harms the underlying concrete decks by exposing the embedded steel reinforcing bars to corrosion and degradation. Baytec SPR thick film coatings offer a proven solution by forming a seamless, elastic waterproofing seal that resists damage caused to concrete by freeze/thaw cycles and corrosion. The Baytec SPR system’s polyurethane backbone yields excellent flexibility that allows the thick film coating to bridge gaps, cracks and microfissures, even when the temperature drops below zero. It is also important to note that the Baytec SPR has been approved by a variety of federal, state and local authorities, as well as civil engineering and consulting firms in the United States and worldwide. As part of the New Jersey rail rehabilitation project, coating sub-contractor PIM Corporation is applying Bayer’s SPR spray system to the surface of the underlying steel decks of two rail bridges located in Plainfield, N.J. To keep service disruption to a minimum, the project is being executed in segments: One track section at a time is rehabilitated, with the surface prepared and coated, then put back into service. “With more than 30 years of experience in thick film coatings, Bayer offers proven waterproofing solutions that have stood the test of time,” said Steven Reinstadtler, market channel manager, Cast Elastomers/Waterproofing Group, Bayer MaterialScience. “The New Jersey rail project is just the latest example of how our Baytec spray system can help extend bridge life by creating a long-lasting waterproof seal between the deck and road surface,” continued Reinstadtler, who notes that this current project marks the fourth and fifth New Jersey Transit Rail bridges that have been waterproofed with Bayer’s Baytec spray system, with more already committed to for Spring. http://www.bayermaterialscience.com
