Kevlar® on Virginia Box Culvert

A new precast box culvert bridge was set in place to replace an old bridge beyond repair. The Virginia Department of Transportation has utilized Fortress Kevlar® for over ten years and turned to it again as a waterproofing membrane for this project.

The Kevlar® was saturated with a two-lift epoxy combined with a #9 Basalt aggregate at every joint, ensuring water and salt do not enter into the joints and cause corrosion of the reinforcement steel cabling. This greatly increase the life of the bridge.
