EDYSTON SR 101 Concrete Bridge Pier Repair

Background

EDYSTON was utilized by RL McCoy, LLC and the Indiana Department of Transportation to rejuvenate a set of concrete piers (4) as part of a bridge infrastructure in Ft Wayne, In. The bridge over Clear Creak on State Road 101 acts as a necessary artery for commercial transportation in the Ft Wayne district to US 30. Due to the excessive deterioration, of the concrete and steel surface, the columns was knocked, sounded, and hydro-jetted. This aggressive process was done to clean the concrete surface of deteriorated concrete and create a profile for injected grout to adhere, Figure 1.

The process of applying is preceded by pressure washing loose debris off of the surface. Based on the deterioration level, the EDYSTON products DURYGEL and DENSYGEL were applied through multiple applications at 1000 sq ft per gallon until 250 sq ft per gallon dosage was reached. A commercial grade, cordless bucket sprayer was used to uniformly apply EDYSTON within 10 minutes of the concrete surface reaching a saturated surface dry condition. The cost of the DENSYGEL product was $5.50 per sq ft for the application to the hydro-jetted surface. The EDYSTON technology accounted for less than 1.5% of the total cost of the project.

Results

Within 24-hrs the grout was injected into the formwork shown in Figure 2. The grout used was a high performance, both high strength and resiliency to physical and chemical attack, approved by the IND-DOT from the 2024 Specifications Guide.
