Washington Heavy Highway Pier Wrapping

Washington DC DoT is responsible for maintaining the area’s heavy highway bridges with many of the older large bridges having eight lanes or more in each direction. The DoT noted some of the bridges’ concrete piers and columns required significant maintenance and repair.

To rehabilitate the piers, the concrete was repaired and the surface was prepared for the application of FRP. The material was then installed around the pier caps – providing confinement, strength and protection from the elements of water, UV and wind.
