Sika® Galvashield® T2

Self-Powered Dual Phase Hybrid Anode Series

Sika® Galvashield® T2 is a second generation hybrid anode system used to control corrosion in reinforced concrete structures. Sika® Galvashield® T2 is a Type 2 anode for embedment within drilled holes in sound concrete. Sika® Galvashield® T2 combines the high level performance of an impressed current electrochemical treatment system with the longterm maintenance-free capabilities of an alkali-activated galvanic cathodic prevention system. The single-unit system does not require complex wiring or an external DC power supply (temporary or permanent). When installed, the inbuilt impressed current component provides an initial phase of high charge density that passivates active corrosion (Phase 1). Then, the anode automatically switches to a cathodic prevention phase, which maintains steel passivity and provides longterm, maintenance-free corrosion protection (Phase 2). The anode spacing and parameters of pre-treatment are customised by Vector Corrosion Technologies based upon the specific condition of the structure and are in conformance with the principals of ISO BS EN 12696:2016.  

Proven Technology - ICCP electrochemical treatment and alkali-activated galvanic anode technologies fused together into a single unit.
Simple Installation - Sika® Galvashield® T2 is a single unit hybrid system with no external power requirements.
Fit & Forget - Sika® Galvashield® T2 operates automatically once installed, reducing access requirements and therefore time and cost.
Long Lasting - Provides corrosion protection for up to 30+ years without the need for maintenance.* Phase 1 can be designed to be repeated at any time if desired.
Measurable Performance - While not critical for the long term operation of the system, the site performance can be measured and validated if required.
