A-1 / A-13 / A-14 Underpasses - Italy
This series of projects included 13 underpasses along major motorways in Italy.
Galvashield® CC
Galvanic Anodes
Embedded galvanic anode that proactively prevents corrosion in sound reinforced concrete.
Galvashield® CC
Galvashield® CC range of embedded galvanic anodes is used to mitigate ongoing 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.

Grout Properties
For optimum performance, use Galvashield® Embedding Mortar when grouting anodes in drilled holes to provide an ionically conductive path to the substrate.
Note: Galvashield CC is also available in custom sizes. Please Contact Us if you require project-specific designs.
What is the X-Series?
Our X-Series of products ensure you get the high performance and long-term protection you need in any environment. Cathodic protection system designers should utilize Galvashield CCX if your structure sees average annual temperatures above 15°C or 60°F or is exposed to high levels of chlorides. To learn more about the X-Factor, read our blog post here.
