Two weeks prevention, 50 years cure
Sika’s new galvanic anode system delivers up to 50 years concrete corrosion protection without monitoring or maintenance. Owners of large, corrosion prone concrete assets such as wharves, bridges, sea walls and the like can now significantly reduce the maintenance costs of those reinforced concrete assets.
Sika, New Zealand’s leading supplier of concrete protection and maintenance products, recently launched two new systems that take concrete repair and protection to a whole new level. The Sika Ferrogard Patch system increases the durability of traditional concrete patch repairs by providing protection against incipient anode corrosion.
The Sika Ferrogard Duo system provides up to 50 years of reinforcement corrosion protection in chloride or carbonation contaminated concrete – without the need for regular monitoring and maintenance – and it is fully compatible with prestressed concrete structures.
The launch of these two new systems is very timely. A large proportion of New Zealand’s infrastructure is now over 50 years old and much of it is located in aggressive coastal environments. It is not surprising therefore that there is an increasing demand from asset owners for extended service lives and reduced maintenance costs of reinforced concrete.
Both Sika Ferrogard Patch and Sika Ferrogard Duo use galvanic protection to prevent reinforcement corrosion, which in turn extends asset life and reduces maintenance costs.
