The paper deals with reinforcing soil structures by means of metallic strips. In chloride contaminated soils, reinforcing strips have to overwhelm the severe corrosion on carbon and galvanised steels, as used in standard applications. Stainless steels (more common grade) do not withstand pitting and crevice corrosion when chloride ions. are present. Conversely, the cathodic protection of stainless steels, attained in the perfect passivity potential range, and applied since the beginning, avoids any localised corrosion occurrence. Such a cathodic protection has been obtained by coupling the stainless steel to the carbon steel. Results of long term testing are presented and discussed.
