Galvashield® CC

Galvashield® CC

Galvanic Anodes
Embedded galvanic anode that proactively prevents corrosion in sound reinforced concrete.

Galvashield® CC

Galvashield® CC range of embedded galvanic anodes are used to mitigate on-going corrosion and to prevent the initiation of new corrosion activity in reinforced concrete structures. Galvashield® CC anodes are alkali-activated (Type 2A) and consist of a high purity zinc anode core that is surrounded by a specially formulated precast cementitious mortar with an internal pH of 14 or greater that keeps the zinc active over the life of the anode.  Galvashield® CC anodes are available in 3 different sizes to fit any structure and level of protection.

The cylindrical anode is quickly and easily installed into drilled holes in concrete that is mechanically sound but has ongoing corrosion activity. Once installed, the zinc anode corrodes preferentially to protect the adjacent reinforcing steel.  For spacing charts, refer to the technical data sheet

Features and Benefits

  • Proven technology: Galvashield® is the original embedded galvanic anode with an extensive 20-year track record.
  • Long lasting: minimum 20-year anode service life when using standard design tables; reduces the need for future repairs.
  • Targeted protection: discrete anodes can be installed to provide corrosion protection in areas with high corrosion potentials or active corrosion.
  • Economical: save money by targeting only the remaining areas of high corrosive risk.
  • Versatile: effective in chloride contaminated and carbonated concrete. Can be used for both conventionally reinforced and prestressed or post-tensioned concrete.
  • User friendly: installation is quick and easy.
  • Low maintenance: requires no external power source or system monitoring.
  • Measurable performance: anode performance can be easily monitored if required.
