Conventional methods to deal with chloride-contaminated concrete require the removal of the contaminated concrete and replacement with uncontaminated concrete. These methods are noisy, dirty, time consuming, costly, and in some cases structurally detrimental. The Norcure system is a rehabilitation method developed to remove salt (chloride ions) from salt contaminated concrete structures without damaging the concrete. The removal of chloride ions stops the corrosion of embedded reinforcing steel and greatly extends the service life of salt contaminated structures.
