AIL’s Dur-A-Span Structural Aluminum Plate Culverts have been quietly maintaining their low profiles — toughing it out in the harsh environments of BC’s lower mainland for the duration. You don’t hear much about them because they don’t need much maintenance and their open-flow designs don’t clog with debris and cause flooding like reinforced concrete box culverts often tend to do.
Chosen over reinforced concrete box culverts for all the right reasons
Increasingly, smart specifiers recognize the many benefits of culverts made from Dur-A-Span:
- Solid, corrosion/abrasion-resistant aluminum
- Larger single opening, greater flow, less flooding
- No joint separation or differential settlement issues
- Bottomless, fish-friendly designs
- Variety of low-profile shapes, footings and end treatments
- Lightweight, easy to ship and install
- Low maintenance, improved life-cycle cost
- We went on a ‘culvert crawl’ around the area in order to show you how well our 2005 installations are performing in their respective corrosive/abrasive environments.

Our 2016 ‘culvert crawl’ takes a closer look at four Dur-A-Span structures that were installed in BC’s lower mainland in 2005. All culverts are in excellent condition and performing well. Water testing results are from April 14, 2016.
