Close Interval Potential Surveys (CIS)

Close interval potential surveys (CIS) are an effective method for assessing the entire structure’s cathodic protection status.

Standard structure to potential surveys tell you the protection levels local to the test stations, but a Close Interval Survey extends this assessment along the entire structure.  In doing so localized, otherwise out-of-sight, risk areas can be identified and resolved.

Close interval surveys are normally performed at system inception to establish a baseline and scheduled, typically 5 year intervals thereafter, with standard test point assessments at shorter time intervals.

Close interval surveys are a great tool for producing a baseline for your structure(s).  Both the native Close Interval Surveys and interrupted Close Interval Surveys should be performed for new and existing installations.

Dreiym has performed Close Interval Surveys all over texas, and can serve any area, including Houston, Austin, San Antonio and Dallas.  Contact Us today to discuss your project.  Initial consultations and quotes are always free.
