As Maine and the rest of the Northeast’s infrastructure ages, it’s necessary to monitor all culverts to make sure they are still performing the function they were designed to do and to prevent problems such as roadway sinkholes or flooding.
These situations can put lives at risk and therefore cost-effective and long-term solutions for repairing and maintaining culverts are needed.
For decades, the norm was to reroute traffic and cut into the road to access a culvert, which could put workers and commuters in danger and cause traffic delays. The safer and more cost effective alternative is to clean the culvert and slip-line it with one of the many types of liner pipes available today. Additional benefits of slip-lining are reestablishing the culvert’s integrity, the installation of fish weirs for the safe passage of aquatic life, and – in most cases – an increase of water flow.
