Abstract: Capillary suction is suppressed by surface impregnation with silane. As a result, ingress of liquid water and harmful ions such as chlorides or sulphates dissolved in water is prevented. In practice, concrete structures are usually cracked. Cracks serve as preferential paths for ingress of water and chloride dissolved in water. The efficiency of water repellent surface impregnation has been studied. Recommendations for applications in practice can be formulated. If cracks occur after surface impregnation, it may be necessary to repeat the protective treatment. Mechanically induced damage (micro-cracks) usually reduces durability of concrete. The reduction of service life of reinforced concrete structures can be avoided if the surface is impregnated with silane. Surface impregnation delays initiation of corrosion in aggressive environment significantly. If chloride contaminated concrete is surface impregnated with silane, the rate of corrosion is reduced.
