The ProblemConcrete corrosion problems occur whencontamination results in a loss of steelpassivity. The resulting ‘Rust’ occupies avolume much greater than the steel itconsumes. This expansion leads to cracking,concrete delamination and eventualstructural implications.

International estimates put the costs ofcorrosion to an economy at 3-5% of GDP.

What causes Corrosion?A number of everyday contaminants can cause steel to corrode in concrete.

• Seawater & airborne salts• De-icing chemicals• Carbon dioxide in the atmosphere• Cast in chlorides• Sea dredged aggregates

Traditional Cathodic Protection SystemsTraditionally, Impressed Current Cathodic Protection (ICCP) hasworked by utilising a small electrical current generated by anexternal power source to control corrosion. Due to the nature of thetechnology, power, monitoring and maintenance are allcontinuously required over its life. This often leads to systems beingoverlooked with time. One independent report indicates that after15 years, there was a 50% probability that the system would not beworking and would require repair. This increased to 75% at 20 years.

Galvanic Corrosion Control systems have increased in popularityover the past 20 years due to their simplicity. No external power ormonitoring are required for their function. This makes them anattractive option, even though they have a finite life and theirperformance cannot be altered once installed.

Galvashield® ™ Next Generation Technology

Galvashield® Fusion™ is a second-generation hybrid anode systemthat combines the designable performance of an ICCP system withsimple maintenance-free performance and installation of agalvanic system. Through extensive innovation Vector hasdeveloped a unit which offers short term ICCP to re-passivate steel(Phase 1) and long-term cathodic prevention to maintain that state(Phase 2). This is achieved with a single unit without the need forany external power or complicated wiring. This two phasetreatment is designed to the performance requirements of BSEN12696:2016.

2nd Generation Hybrid SystemPhase

A high but short term electrochemical treatment to effectively mitigate corrosion and re-passivate steel.The aim of Phase 1 is to reinstate the alkaline environment around the steel.

Phase Once Phase 1 is complete the units automatically switch to a corrosion prevention system, where the galvanic current maintains steel passivity for the life of the system.

Key BenefitsProven TechnologyICCP and alkali-activated galvanic anode technologies fusedtogether into a single unit.

Simple InstallationUnlike ICCP and galvanic anodes, Galvashield® Fusion™ is a singleunit hybrid system with no external power requirements.

Fit & ForgetGalvashield® Fusion™ operates automatically once installed,reducing access requirements, time and cost.

Long LastingProvides corrosion protection for 30+ years without the need formaintenance.*

Measureable PerformanceWhile not critical for the long-term operation of the system, siteperformance can be measured and validated if required.

EconomicalUp to 40% reduction in installed cost when compared to otherembedded galvanic systems.

*As with all galvanic protection systems, service life is dependent upon anumber of factors including reinforcing steel density, concrete conductivity,chloride concentration, humidity and anode spacing.
