Corrosion prevention on wharfs, bridges, marine and civil-engineering structures
CWS products provide not only waterproofing, but concrete and steel reinforcement protection. They are ideal to prevent corrosion on applications such as bridges and especially wharfs and marine structures, which are constantly attacked by chloride.
Even the best concrete develops hairline cracking allowing water and corrosive materials, such as carbon dioxide and chlorides to penetrate the concrete and attack the steel reinforcement. The result of the corrosion and rusting is expansion of the steel and ultimately destruction of the concrete. Unfortunately, sometimes this results in demolition of the structure years before its original design life is achieved and even worse: significant loss of life in the case of bridge collapses etc. Recent bridge collapses in Genoa, Italy and the USA spring readily to mind.
