An aging Haliburton County culvert needed to be relined to extend its service life without the increased cost, traffic interruption and environmental impact of a full replacement. The municipality was considering various options and materials for this effort, but AIL’s proposal had a brighter light at the end of its 24.7 m tunnel. It was the glowing performance attributes of AIL’s Dur-A-Span Structural Aluminum Plate.
No installation worries with tough, self-healing surface.
With Dur-A-Span, the contractor didn’t have to worry about scratching it during handling and insertion — a key concern with the extra handling required for a reline insertion. That’s because Dur-A-Span’s tough, self-healing oxide surface film reforms immediately if it is mechanically damaged or corroded in aggressive soft water or saltwater environments.
The Pipe Arch was our PA6-18 design with a span of 5 m and a rise of 3.2 m. Construction took only a little over a week, starting on November 24 and completing on December 4, including grouting.
Go the distance with Dur-A-Span
Dur-A-Span Aluminum Structural Plate has been going the distance — through many years of wet/dry, corrosion/abrasion cycles in over 10,000 structures worldwide — beating the usual heavyweight contenders, like precast concrete, on overall performance and cost. And now, thanks to our innovative design advances and reinforcing rib technologies, Dur-A-Span can go even farther (and wider) to outperform all challengers.
