We provide permanent protection for reinforced concrete structures against corrosion. With cathodic corrosion protection (CCP), we ensure load-bearing capacity, extend service life, and prevent costly repairs. Our solutions are sustainable, innovative, and intelligent, ensuring that buildings remain intact in the long term—and that your investment is permanently secured.
Wherever reinforced concrete is exposed to pollutants such as chlorides from deicing salts, CO₂, is exposed to the environment or other corrosive conditions, a CCP system offers effective protection through electrochemical processes. Whether in underground parking garages, bridges, or tunnels, CCP reduces active corrosion and preserves the building fabric permanently.

Cathodic corrosion protection is not only sustainable, but also quick to implement. CCP eliminates the need for interventions in the supporting structure and support measures. This reduces closure times and parking space losses and extends the service life of structures.
Cathodic corrosion protection can be used to protect and repair bridges, which is often not possible with other repair methods.
For linear structures such as tunnels is CCP ideal for repairs. This means that pilgrim steps can be avoided during construction.
In cathodic corrosion protection (CCP), a precisely controlled electrical potential is applied to the reinforcement to be protected. With the aid of an additional anode, a controlled potential difference is created, which effectively stops the electrochemical corrosion process. This ensures the long-term load-bearing capacity and service life of reinforced concrete structures.
Titanium anodes with mixed metal oxide coating or, alternatively, carbon anodes are often used as anodes. This system permanently places the reinforcement in a cathodic state, thereby suppressing corrosion. The chemical reactions necessary for corrosion are specifically transferred to the externally arranged, inert anode with the aid of electric current.
The components:
Cathodic corrosion protection not only protects economically, but also particularly sustainably – especially where conventional concrete repair reaches its limits. Thanks to modern, innovative and intelligent control systems regulate the protective current precisely – for maximum efficiency and minimal intervention.
Choose CCP with HWP:
Do you have questions about cathodic corrosion protection for your structure? Here you will find the most important topics at a glance:
In chloride-contaminated or carbonatized Reinforced concrete components in which corrosion is already active. It can also be used preventively. In this case, the CCP is installed during the construction of the building and prevents that corrosion is triggered.
When properly installed and maintained, a cathodic protection system provides protection for decades. Professional testing of some types of anodes confirms their durability of up to 100 years.
Our operational units take care of every step—from anode installation and power supply to operation and service. Everything from a single source.
CCP systems are implemented in accordance with DIN EN ISO 12696 – the relevant standard for cathodic corrosion protection of steel in concrete. In addition, the CCP is regulated via the repair principle 10.1 Application of an electrical potential via the TR-IH. Since only qualified personnel are permitted to perform this procedure, personal certification in accordance with DIN EN ISO 15257. Of course, they have our contractors have the appropriate qualifications.
Whether it’s a bridge, underground car park, or sewage treatment plant, we develop a tailor-made protection concept for every structure. Contact us for a personalized consultation and find out how HWP Bauwerkserhaltung can provide lasting protection for your reinforced concrete.
