Ontario reline sees the light with Dur-A-Span.

An aging Haliburton County culvert needed to be relined to extend it's 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 the AIL Team'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 Aluminum Alloy Structural Plate.

With Dur-A-Span the contractor doesn'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 softwater 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.

Dur-A-Span Aluminum Structural Plate has been going the distance - through many years of wet/dry, corrosion/abrasion cycles in over 1,000 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.
