In 1985 and 1986, thirteen bridges on the newly constructed Coquihalla Highway required waterproofing treatment for the existing concrete infrastructure to protect the reinforcing steel from corrosion. Most of the bridges were constructed and treated during adverse winter weather conditions.
The Krystol T1 & T2 Waterproofing System was the only system compatible for wet weather application. The treatment was applied to both the vertical and horizontal concrete surfaces. The system continues to perform as specified.
