The Corrosion Severity Factor (CSF) was developed to enable the inspector in the field to easily transmit a description of the corrosion condition of a buried steel tower anchor. The CSF is determined by the following criteria
The CSF Rating is determined by the worst part of the anchor!
Replacement may be warranted. The CSF can help you determine the necessity of installing AnchorGuard®. If a CSF of 2 is found at a depth of two feet below grade, AnchorGuard is recommended. When a CSF of 3 or higher is found at a depth of two feet below grade on any tower, further inspection is highly advisable and installation of AnchorGuard is recommended.
