Matergenics – Pittsburgh has created a specialized market in soil corrosivity,  corrosion risk assessment and identification of corrosive hot-spots for underground assets and infrastructure that is not considered by traditional Close Interval Surveys (CIS) and circumvent functioning cathodic protection (CP). Our dedicated soil lab has rapid turn-around times and is supported by a multidiscipline team of soil specialists,  NACE certified materials and corrosion engineers, CP design and installation specialists, coatings specialists, chemists, and and certified lab and field technicians. The combination of field and lab analysis provides essential data for soil mapping verification, geotechnical, asset management, site surveys, CP installations, and failure analysis.

The construction of our corrosion and agricultural assessment maps consists of two phases:

  • In Phase I, the relevant data will be collected, categorized, and analyzed with respect to the project objectives. The information will consist of several distinctive sets of data related to the project.
  • In Phase II, a knowledge-based approach along with adequate and accurate equipment, and advanced techniques, will be used to collect, analyze, and verify the Phase I corrosion mapping at statistically representative selected sites.

Let’s build something together.
