Culvert Repair

In 2016 Kenway installed a unique culvert lining system for the Maine Department of Transportation in Mount Desert Island (MDI), Maine.

Previously, in 2009, Kenway collaborated with the University of Maine to develop a system for repairing culverts. This system allows for the rehabilitation of corroded steel culverts without the excavation of the roadway passing over the pipe. When the need for a culvert lining arose in MDI, Kenway stepped up to the challenge. This project demanded the type of pipe degradation and installation of aquatic wildlife passage components on top of the liners. Our system was the only one that met both requirements.

In addition, Kenway’s solution had another advantage! The allowance for a minimum invert elevation increase — typically 1.5 to 2 inches total.

The Results! 

The culvert repair system took less than five days for installation, and it’s expected to last more than 50 years! Many groups involved in the installation were incredibly happy with the results. The contractor finished well ahead of schedule and found the system easy to operate. Perhaps the most satisfied group involved were the fish, who had a new passageway up through the brook.
