Reinforced concrete protection


Normally the reinforcement in alkaline concrete is protected against corrosion by a thin protective film. This film can be destroyed by chlorides and carbonation and finally lead to corrosion. Especially chloride induced corrosion leads to considerable damages, which influence the bearing capacity of the reinforcement and lead to the collapse of buildings in the worst case. Traditional repair and rehabilitation measures are very often not suitable. In this case cathodic corrosion protection is an effective and economic alternative. 


Cathodic corrosion protection is regulated by the standard EN 12696 and known as rehabilitation measure for reinforced concrete structures for about 25 years. In our width cathodic protection systems are mainly applied at bridges and parking garages as well as tunnels, sea water buildings or at protected historic monuments like churches.
