Galvanic cathodic protection assessment in a concrete bridge arch

Engineering Services Delivered

As part of our contribution to advancing the rehabilitation of the University Bridge, we implemented a field-based galvanic cathodic protection test system. This included the installation of embedded zinc anode panels, integration of monitoring instrumentation, and validation through long-term field observations and predictive modelling.

Project Highlights

• Designed and implemented embedded zinc anode systems for corrosion mitigation
• Installed reference electrodes and centralized junction boxes for performance tracking
• Conducted early-stage benchmark testing to support future maintenance planning
• Applied predictive modelling to optimize design and confirm protective current distribution

Outcomes

• Validated the effectiveness of GCP in moisture-prone regions
• Provided practical insights into spacing, material consumption, and current efficiency

This work exemplifies a performance-based engineering approach that combines field deployment and modelling to extend the service life of aging concrete structures.
