We frequently test soil samples to determine how corrosive they could be. Our corrosivity packages include:
- Basic: Soil oxidation-reduction (redox) potential, Sulfide, Chloride
- Ten-point Soil Corrosivity: Soil pH, EC, Sulfide, Redox potential, and Minimum Laboratory Resistivity
- Complete Corrosivity: pH, EC, Sulfide, Chloride, Redox potential, Sulfate, Chloride, and Minimum Laboratory Resistivity.
We analyze these packages according to various international and state specific test methods. Our most popular report is the Complete Corrosivity with AASHTO test methods. Some people prefer the Complete Corrosivity with ASTM test methods. If you are from Colorado you may be interested in our Complete Corrosivity with CDOT test methods. If you require specific methods not listed here contact us and we can probably put together a new template. One example of a custom template is an ASTM 2-electrode variant with no interpretation.
Typical turnaround times for these analyses are 10-11 business days. We need a one-gallon bag of soil to fill the MLR boxes.
We can also test corrosivity of water. We need the sample temperature at the site but we are then able to compute the Langelier Saturation Index (LSI), Ryznar Stability Index, and the Larson-Skold index. (Sample Report).
Many important structures, pipelines, and storage tanks are buried underground. Soils high in moisture, conductivity, salts, or acidity will be more corrosive. Our corrosivity packages help engineers determine when and where costly sacrificial galvanic anodes, cathodic protection, or protective coatings are required.
We also perform soil classification (% sand, silt, and clay) if there is a concern about proper aeration or drainage. Here is a sample report of this type.
