Durability's assessment saves owners more than one million dollars
Durabilities assessment and design of conductive coating impressed current cathodic protection system saves owners more than one million dollars.
The Problem - Corrosion
Corrosion of steel in concrete occurs when conditions in the concrete change from a protective environment to an environment which supports and promotes the corrosion process. Once the process begins it creates expansive iron oxides that exert tensile stresses on the surrounding concrete. Being weak in tension, the concrete develops cracks, delaminations and spalls resulting in damage. Over time corrosion will continue to deteriorate the concrete, leading to escalating repair costs and eventual replacement. Numerous options are available to address this destructive process but selecting the wrong strategy could result in undesirable side effects.
It is therefore important to identify the root cause, so that the problem can be properly diagnosed and the best corrosion protection solution can be selected. Durability helps extend the service lives of assets through the development of a clear understanding of corrosion risk and current conditions, resulting in valid diagnoses and selection of best alternatives for optimum corrosion management.
