Chemical Sealers as Corrosion Inhibitors: Naselle River Bridge 101/24

This Post Construction Report provides an overview of the selection of a chemical sealer and its use as a method of protecting the girders and piles of the Naselle River Bridge from the intrusion of chloride ions. The structure treated is located in a marine environment. Chem-Trete Silane sealer was used for this structure and applied as specified by the manufacturer. After 1 1/2 years exposure to a salt environment no deterioration of the concrete has been detected. Monitoring of the structure will continue under Washington State Department of Transportation's Bridge Inspection program
