Bridges made of concrete/steel concrete are exposed to multiple stresses in the form of general environmental influences such as humidity, damp, heat and cold, wind, snow and ice loads. Added to this are heavy vibrations caused by traffic volume, the use of gritting salt, rock falls and much more. All of these factors accelerate the ageing process and make regular restoration, combined with effective corrosion protection methods, necessary.
The basis for long-lasting bridge renovation is professional high-pressure and ultra-high pressure cleaning, to reveal the damage, analyse it and, at the same time, prepare for repairs to be made. We are also competent partners in this area with many years of practical experience. Examples of projects we have completed include the Cologne-Frankfurt ICE route and the renovation of the Elbe Tunnel.
