Water had leaked through an expansion joint between the wall and floor of a 250-foot long tunnel for at least eight years, degrading pipe supports.

The leak kept at least two feet of water on the tunnel floor and hampered workers inside the tunnel who were repairing the supports.

Team personnel recommended a water activated urethane resin and variable pressure injection to stop the leak. Tunnel engineers agreed. Team personnel installed injection ports, then pumped and sealed the leak.

The tunnel was pumped dry and workers repaired the pipe supports.

A leaking expansion joint in a tunnel beneath Louisiana's IntraCoastal Canal prevented workers from safely making electrical repairs.

Team, Inc., was awarded the job of sealing the leak. While traffic was diverted to an opposite lane through the tunnel, Team removed old joint material and replaced it with an expanding gasket retention seal. Utilizing the variable pressure injection method and a water-activated hydrophyllic urethane resin, Team technicians sealed half the leaking expansion joint.

Traffic was switched to the opposite lane and Team technicians completed sealing the leaking joint.

Workers were then able to enter the tunnel and make the electrical repairs safely.
