GalvaJacket™ Zinc Anode System

Stay-in-Place Structural Protection for Severe Corrosion Environments

The GalvaJacket™ Anode System is a galvanic cathodic protection solution engineered for high-risk reinforced concrete and steel piling structures. This all-in-one system combines a zinc mesh anode with a custom-fabricated fiberglass-reinforced polymer (GRP) stay-in-place jacket, delivering both corrosion protection and structural rehabilitation in one streamlined installation.

Unlike impressed current systems, GalvaJacket™ requires no external power supply, making it a low-maintenance, high-performance solution for field conditions across North America, including coastal, marine, and deicing salt environments.

Each jacket is custom-built to fit the specific dimensions of piles, columns, and beams, allowing for fast site installation and precise integration with “form-and-pump” concrete repair techniques. The embedded zinc mesh delivers targeted protective current to stop ongoing corrosion and extend the life of the asset.

Features & Benefits

The GalvaJacket™ System is trusted in thousands of installations and proven to protect infrastructure exposed to chloride-induced deterioration. Key advantages include:

• Proven Performance: Over 20,000 units installed with zero reported defects.

• Corrosion Mitigation and Structural Repair in One: Simultaneously repairs and protects deteriorated concrete with active corrosion and spalling.

• Fully Assembled for Fast Installation: Jackets are pre-assembled and ready for efficient, site-friendly deployment.

• No External Power Required: Operates through galvanic action, reducing complexity, cost, and maintenance compared to impressed current systems.

• Custom Fit for Any Shape or Size: Manufactured to exact dimensions of piles, columns, pile caps, and beams, minimizing on-site modification.

• Dual-Purpose GRP Formwork: The rigid fiberglass shell acts as a stay-in-place form for placing cementitious repair material, eliminating the need for temporary formwork.

• Self-Regulating Output: The zinc anode self-adjusts based on temperature, humidity, and concrete resistivity, delivering stable protection.

• Long Service Life: Designed to last 25 years or more, depending on environmental conditions and anode spacing.

Best Applications for GalvaJacket™

The GalvaJacket™ System is optimized for marine, transportation, and industrial structures exposed to aggressive corrosion environments. It is especially effective in areas difficult to access or where traditional formwork is impractical.

Recommended Use Cases:

• Prestressed Concrete and Steel H-Piles: Protects structural members exposed to seawater, brackish water, or deicing chemicals.

• Bridge Columns and Piers: Ideal for protecting columns and supports in splash zones or tidal environments.

• Pile Caps and Cross Beams: Delivers durable protection and repair for high-risk structural elements near or below waterline.

• Structures Affected by Chloride Contamination: Suitable for any reinforced concrete element suffering from chloride-induced corrosion.

• Ports, Harbors, and Marine Terminals: Long-lasting, low-maintenance protection for critical infrastructure with limited access and high exposure.
