Concrete repair of walls and facades
Concrete protects the existing steel reinforcement from corrosion due to its alkalinity (ph-value 14). External influences, such as water, carbon dioxide and salt stress, reduce the alkalinity, depending on the type and features of the concrete. As soon as the natural corrosion protection of the reinforcing steel is lost due to this carbonation, damage, e.g spalling due to steel corrosion will be visible. The concrete must then be repaired urgently in order to prevent further damage. Weber offers innovative, tested concrete replacement and surface protection systems. The concrete replacement system weber.rep duo also fulfils the highest requirement class of EN 1504-3 - Class R 4.
