Close Interval surveys (CIS)

Close interval potential surveys are a great tool for producing a baseline for your structure(s). But they are only one piece of the puzzle, and they are really of best use in the first stages of project development. To get the greatest benefit from these initial surveys, ensuring cathodic protection systems remain up to NACE standard as structures age, modify, or expand, is required. Both the native Close Interval Surveys and interrupted Close Interval Surveys should be performed for new and existing installations. In practicing this, you preserve the quality and safety of your cathodic protecting systems over the course of a structure’s lifespan.
