The service includes design of cathodic protection systems for reinforced concrete structures. This covers selection of anode system, power supply and control units, which are important for a well-functioning system. The offering includes a wide range of anodes and equipment for new and existing structures as well as customised power supplies and control units. Force Technology also develops and produces cathodic protection systems, including the durAnode® system, which is available in its 4th generation.
Corrosion protection and cathodic systems
Cathodic protection of reinforced concrete structures
Protect reinforced concrete structures with cathodic protection that reduces repair costs and extends life expectancy.
Cathodic protection of reinforced concrete structures supports owners when chloride contamination creates a risk of ongoing corrosion and premature degradation. The need typically arises in aggressive environments such as seawater, areas exposed to thawing salt and swimming pools, or when cathodic protection forms part of the maintenance strategy for reinforced concrete structures. If corrosion continues, the structure can deteriorate further and lead to future repair work.
Maintenance context and structural preservation
The service is relevant in situations where other repair methods may otherwise be extensive. It is also relevant where preserving the existing structure is important. This helps building owners reduce future repair costs and extend the life expectancy of reinforced concrete structures. The service is part of our expertise area Corrosion protection and cathodic systems.
Challenges
When reinforced concrete structures are exposed to chlorides, ongoing corrosion can accelerate degradation and increase repair needs.
Ongoing corrosion drives further degradation
When chloride contamination is present, steel reinforcement can continue to corrode and contribute to further degradation of the concrete structure.
Conventional repairs can require major intervention
Demolition and replacement, or removal of concrete from the most chloride-affected areas, can require extensive intervention in the structure and affect the existing construction.
Structural material may need to be removed
Repair methods can involve removal of concrete or brickwork that is important to the strength of the structure.
Later installation can become more extensive
If cathodic protection is not considered during construction, later installation can require a more extensive installation process and provide fewer design options.
Benefits
Reduce future repair costs and help preserve the existing structure with cathodic protection.
Reduce future repair costs
Cathodic protection can reduce the cost of future repair work by stopping ongoing corrosion before degradation develops further and leads to more extensive repair measures.
Preserve material important to strength
Cathodic protection can be used instead of more drastic repair methods and helps avoid removing concrete or brickwork that is important to the strength of the structure.
Improve later installation options
When cathodic protection is prepared during construction, later installation can be carried out with lower installation costs and better possibilities for system design.
