First the bridge was inspected to accurately record the damage and formulate a treatment plan. This inspection included looking at all structural components of the bridge, including each wall of the bridge. Next, demolition of the spalled and delaminated concrete was completed. This removal of the corroded and spalled concrete is important to provide a more level and smooth surface for application of the chosen Surtreat system.
After this preparation of the concrete surfaces, the application of Surtreat’s corrosion inhibitor and rust converter begins. These products are applied to specifically designated repair areas and the surrounding concrete around these hotspot areas. The application of these products not only treat the current corrosion that is located within the embedded and exposed rebar, but these products protect again future corrosion to the structure.
After the application of the corrosion inhibitor and the rust converter, SurCoat, Surtreat TPS Repel, and TPS II are all applied to the structure to finish the revitalization project. SurCoat and the cement paste are applied to the structure, then the TPS Repel and TPS II system is surface applied using a sprayer.
