At Matergenics GIS, we work with you to map data that you want to see.
Soil Corrosion Mapping
We were retained by a major electric utility company to assist them in developing a corrosion risk assessment map for their service territory. The genesis of this project started when they found severe below-ground corrosion on several steel structures after a short time in service. Considering that they had several thousand structures across their service territory, the thought of inspecting each and every one of the structures would be a monumental as well as a costly task. In consulting with Matergenics it was decided that the best way to approach this would be to develop a corrosion risk assessment map of their service territory. The map would identify areas of high, medium and low below-ground corrosion risks. Once the map was completed our customers were able to concentrate their resources on structures located in high corrosion risk areas. The mapping effort has been completed and we have provided the client with a map in ArcGIS which they will put into their GIS system. Customers are using the map for many things (operation, maintenance, geotechnical) with regards to other steel corrosion efforts.
We were retained by a major utility company to assist them in developing an atmospheric corrosion risk assessment map for a proposed telecommunication line. The company was interested in materials selection for their structures. In consulting with Matergenics, it was decided that the best way to select materials based on environmental conditions would be to create an atmospheric corrosion risk map. The map would identify areas of high, medium and low above-ground corrosion risks. Using this information we were able to successfully offer the exact material type and coating to use on their proposed structures to minimize corrosion.
Corrosion Rate Prediction
We were retained by a major utility company to assist them in developing a corrosion rate prediction chart for hundreds of their telecommunication structures. Matergenics completed an on-site field assessment for each structure, exposing multiple anchor shafts at each asset to visually assess the extent of corrosion. Soil samples were also taken and analyzed in the lab. By combining field measurements with lab results, a final corrosion rate prediction chart was created for each anchor inspected at each site. The chart compares structure age with maximum pitting depth/corrosion rate.
