Balancing the Tide: MicroNex’s Breakthrough in Bridge Pile Protection

The tidal zones of bridge and wharf piles are among the most critical and vulnerable structural

elements as they are subject to accelerated deterioration from constant wet and dry cycling and chloride ingress. Until now, achieving full corrosion protection in these sections has been highly complex. Grout degradation around embedded anodes in the tidal zone compromises long-term performance, while high tide conditions often lead to rebar overprotection due to uncontrolled current delivery.

Traditional corrosion protection for concrete bridge and wharf piles in tidal zones relies on a dual system: embedded concrete anodes for atmospheric exposure in tidal areas and water anode systems for submerged sections. While effective, this approach can result in overprotection during high tide and gradual system degradation.

High Tide Level

MicroNex introduces a breakthrough solution by dynamically regulating current output in response to tidal fluctuations or reference electrode potential. This ensures optimal protection across varying exposure conditions without the risk of overprotection. By integrating advanced anode encapsulation techniques developed by Remedial Technology in tidal and splash zones with intelligent current control, MicroNex redefines tidal zone protection, offering a more balanced, efficient, and sustainable corrosion management strategy for marine infrastructure.

1. Circuit Control Based on Online Tide Forecasts

MicroNex systems now integrate live tide data to automatically control circuit operation. Outputs switch on or off depending on forecasted water levels, ensuring precise protection while optimising energy use. The system operates automatically to reduce errors and enhance safety. Energy-efficient design minimises power consumption and environmental impact. All automation events trigger real-time email notifications, enabling remote monitoring and timely responses to system events.

2. Circuit Control Based on Local Reference Potentials

For installations combining water and concrete ICCP systems, circuits can now respond to user-defined reference potential thresholds. This prevents overprotection in tidal and other critical zones, prolonging system life and maintaining optimal performance. The flexible design is compatible with both fixed and portable systems and can be customised for different installations.

Conclusion

By combining advanced automation, environmental monitoring, and flexible controls, MicroNex redefines corrosion protection for bridge and wharf piles. Our ICCP systems now deliver smarter, safer, and more energy-efficient solutions, protecting critical infrastructure today while future-proofing for tomorrow.
