Rehabilitation of sheet pile wall in Duluth, USA

1,200 feet (360 m) of severely corroded steel sheet pile wall was rehabilitated for Hallett Dock Company using Acotec’s Humidur coating and DZI cofferdam.

Over 12,000 square feet of corroded sheet pile wall was covered with pre-coated steel plates.  The voids between the protection plates and the existing piling were filled with stud-reinforced cement grout and sealed with marine epoxy grout.  Additionally, 1,200 feet of new timber fenders were installed. 

The project saved the client money as this method increased the life time of the dock wall at a fraction of the cost of installing a new dock wall.

The project was completed in 5 weeks, well ahead of schedule.
