Through our many different service offerings, Highridge is able to provide for any of your corrosion needs, large or small. Our teams operate throughout the continental U.S.


External Corrosion Direct Assessment (ECDA)

With experience and expertise, Highridge has the capability of fulfilling your complete ECDA project. We can assist our clients with their specific needs with anything from a turn key program to a contract support role of field data collection. From data collection to analysis, Highridge can supply an abundant amount of reliable data and reporting.

At the customer's request and dependent on field scenarios, Highridge can perform two types of ECDA surveys.

  1. Integrated DCVG/CIS Survey with Soil Resistivity and depth of cover
  2. ACVG/CIS Survey with Soil Resistivity and depth of cover

Highridge's survey data is presented with the following additional details: reporting of anomalies; current source information; depolarization report; IR drop report; Depth of cover report; Below -.850mV report. Once the data has been collected our team of analysts score the results before a consulting engineer reviews the findings. The final report contains a copy of all data collected with detailed summary of the field work.

The Highridge management team began work on a high profile ECDA project by setting up data integration systems and implementing a review process to keep issues in check. This work continues through 2018 as we develop software to help with data organization and reporting. This along with other techniques will help improve field process and result in a turnkey process for our customer's ECDA projects.
