Sika® Galvashield® XP Types

Embedded Galvanic Anodes for Corrosion Prevention

Sika® Galvashield® XP Compact /XPT/XP2/XP4 embedded galvanic anodes are used in concrete rehabilitation to prevent the formation of new corrosion sites adjacent to completed patch repairs.

Sika® Galvashield® XP Compact/XPT/XP2/XP4 anodes consist of a sacrificial zinc core that is activated by the surrounding specially formulated cementitious mortar.

The anode is quickly and easily fastened to the exposed reinforcing steel. Once installed, the zinc core corrodes preferentially to the surrounding rebar, thereby providing galvanic corrosion prevention to the adjacent reinforcing steel and mitigating ‘Incipient Anode’ formation.

Sika® Galvashield® CC

Embedded Galvanic Anode for Corrosion Control

Sika® Galvashield CC embedded galvanic anodes are used to control ongoing corrosion and to prevent the new formation of corrosion sites on reinforced concrete structures. The specially formulated precast cementitious mortar surrounds and activates the sacrificial zinc core.

The cylinders are available in a variety of sizes and are quickly and easily installed into concrete to control corrosion activity. When correctly installed and connected the zinc anode corrodes preferentially to the surrounding steel, providing galvanic corrosion prevention and control to the adjacent reinforcement.
