Meeting the Challenge
Protecting Bridges
Reinforced concrete bridges are constantly under attack by the destructive effects of moisture and chloride-induced corrosion. Without proper protection, the structural integrity of a bridge is soon compromised, leading to expensive remediation efforts and a shortened life span. Once the moisture and chlorides have reached the reinforcing steel, an expansive oxidation process begins to take place. This causes the formation of cracks and spalling in the concrete. When cracking takes place and is combined with weathering effects such as freeze/thaw damage or accelerated corrosion in hot weather climates, this deterioration takes place at a faster pace.
With over 50 years of experience in 90 countries around the world, the Xypex Crystalline Technology has been used in bridge structures to waterproof, protect, repair and enhance the durability of concrete subject to water and chloride attack. In challenging environments exposed to salt or fresh water, de-icing chemicals, freezing cold or blistering heat, or where chemical resistance to sulphate attack or ASR is necessary, Xypex is a highly respected partner in extending the service life of bridges.
