Fiber Reinforced Plastic (FRP) culvert rehabilitation is the latest composite highway infrastructure repair technology pioneered by our team. We design for steel culverts exceeding 3’0. Existing HDPE slip line methods and concrete invert liners come with extended installation schedules.
Moreover, they have multiple negative impacts on the environment. Partnering with the University of Maine’s AEWC Advanced Structures and Composites Center, we developed a composite invert liner. The liner restores the original structural integrity of the culvert with minimal environmental impact and most importantly, a reduced installation cost.
By using the FRP culvert rehabilitation system, transportation departments can accomplish more maintenance projects with their existing budgets.
