Galvashield XP Anodes

The Galvashield® XP range of embedded galvanic anodes
are used to mitigate ring anode corrosion when repairing
reinforced concrete structures.

Description

The Galvashield® XP range of embedded galvanic anodes
are used to mitigate ring anode corrosion when repairing
reinforced concrete structures. Designed for optimum
performance and ease of installation, the alkali-activated (Type
1A) Anodes are comprised of high-purity zinc cast around a
steel tie wire with an enhanced, formulated cement-based
mortar with an internal pH of 14 or greater that keeps the zinc
active over the life of the anode. The Galvashield® XP range
of anodes utilize the contractor-friendly One-and-Done™
single-wire connection. Once installed, the zinc anode corrodes
to provide galvanic corrosion prevention or corrosion control
to adjacent reinforcing steel.

Applications

• Mitigates ring anode formation (halo effect) in the patch repair applications
• Bridge widening and other structure modifications
• Slab replacements, expansion joint repairs and other interfaces between new and existing concrete
• Repair of prestressed and post-tensioned concrete
• Chloride-contaminated or carbonated concrete
• Repair of structures with epoxy-coated rebar
• Extends the life of concrete repairs
• Extends the life of joint repairs

Advantages

• Proven technology – Galvashield® is the original
  embedded galvanic anode with an extensive 20-year
  track record.
• Independent testing – indicates concrete repair service
  life can be extended by more than 400%.
• Type 1A anode – alkali-activated to maintain activity of
  zinc; meets building code requirements that prohibit
  intentionally added constituents that are corrosive to
  reinforcement within the repair area.
• One-and-Done™ connection innovative single wire
  connection can be installed up to 2x faster than the
  traditional two-wire connection, saving 50% on installation
  labour cost.
• Cast zinc core – provides high anode utilisation and a
  secure long-term connection between the zinc and the
  integral lead wire.
• BarFit™ design – grooved edges on Galvashield® XP2
  and XP4 anodes assist with secure anode placement.
• Steel connection wires – Provides dependable steel-to-steel contact with no intermediate materials such as
  galvanizing that may compromise the long-term electrical
  connection.
• Economical – provides localized protection where it is
  needed the most, at the interface between the repair and
  the remaining contaminated concrete.
• Versatile – can be used for both conventionally reinforced
  and prestressed or post-tensioned concrete.
• Low maintenance – requires no external power source or
  system monitoring.
• Long lasting – 10 to 30-year anode service life* reduces
  the need for future repairs.
• CSP-3 Surface Profile – raised ridges provide increased
  surface profile to promote mechanical bond with repair
  mortars and concrete.

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