Overview of Soil-Compass

Soil corrosion refers to corrosion metals and alloys from exposure to soils. The severity of soil corrosion is determined by many factors, including temperature, moisture and oxygen availability, soil resistivity (soil condition and characteristics), soil type (water drainage capability) and homogeneity (variation in soil type), microbial activities, stray current drainage, and coating type, age, and condition. Soil-Compass is the only device and OS independent software tool on the market for the prediction and modeling of soil corrosion for metals and alloys. Designers, architects, engineers, consultants, operation personnel, maintenance and inspection engineers can quickly determine the corrosion depth, the corrosion rates, and the remaining life of the structure or components, anytime, anywhere, on any device running any OS without the need to install or download anything. Soil-Compass also predicts the soil corrosivity class, the likelihood of microbiologically-influenced corrosion (MIC), DC stray current corrosion and AC corrosion in compliance with ISO 18086. Soil-Compass software models the effects of the following critical factors on soil corrosion:

  • Soil type

  • Soil temperature

  • Soil resistivity

  • Soil pH

  • Soil moisture content

  • Soil chloride content

  • Soil carbonate content

  • Soil sulfate content

  • Soil sulfide content

  • Soil redox potential

The outputs of Soil-Compass include the following:

  • the soil corrosivity category,

  • the corrosion depth,

  • the corrosion rate,

  • the remaining life or the time-to-perforation,

  • the mode of failure,

  • likelihood of microbiologically-influenced corrosion (MIC) in the soil environments

  • the risk of DC stray current corrosion and AC corrosion.

Figures below show the screen shots of Soil-Compass.


Figure 1 Soil-Compass Predicts the rate of soil corrosion (including MIC) and the remaining life of structures.


Under the specified exposure conditions shown in Figure 1 above, Soil-Compass predicts, the corrosion rate, the accumulated depth of corrosion at the specified age, and the remaining life of the structure. The predictive engine used in Soil-Compass for the modeling and prediction of soil corrosion of metals and alloys complies with applicable international standard ISO 18086 and relevant industry best practices.


Using Soil-Compass is as easy as 1-2-3.

(1) Select the Material & enter the Age and Thickness of the structure.

(2) Enter the soil property data.

(3) Review the prediction results.

The following figures show the screen shots of Soil-Compass.
