Epoxy Polymer Extends Life For World's Longest Covered Bridge It’s a smoother and safer ride for motorists crossing over the Hartland Covered Bridge in Hartland, New Brunswick, Canada—the world’s longest covered bridge. The bridge deck has been covered with an epoxy polymer overlay from Unitex.
by Shawn Merrithew Bridge closed again, repairs continue ... She said the polymer should enhance the 107-year-old bridge's lifespan. Developed by Unitex Chemicals, the epoxy polymer overlay is more flexible and more corrosion-resistant than asphalt, says Unitex president John Grissinger...
by Jerry Byrne The spread defense: Crews save significant time and maintenance costs with overlay in Kansas The last time Wildcat Construction Co. repaired the I-135 bridge in Wichita, Kan., more than 20 years ago, it took nearly two years, and lanes were closed or diverted both day and nigh
By Rebekah Rosenfeld Kansas bridge polymer surface project is largest in United States. When it came time to resurface the concrete on a portion of one of I-135’s expressways in Wichita, the Kansas Department of Transportation (KDOT) decided to repair the 1.76 million square feet using epoxy.
