Soil Corrosivity Testing

Established in 1993, our soil and water lab has performed corrosivity analyses on over 100,000 soil, water and concrete samples. Parameters evaluated:

  • Electrical Resistivity
  • pH
  • Common Soluble Salts
  • MIC-related Sulfide
  • Oxidation-reduction Potential

Soil Corrosivity Studies

Corrosivity lab testing can be accompanied by a soil corrosivity study to accomplish two objectives:

  • Classify the aggressiveness of soil toward construction materials
  • Provide recommendations to minimize corrosion


  • Particle Size Analysis of Soils
  • Ion Chromatography (Metals and Inorganics)
  • UV/Vis Spectrophotometry
  • Soil Thermal Resistivity
  • Linear Polarization Resistance
  • Chloride and pH in Concrete
  • Reflected-light Microscopy (2,000x)
  • Online Sample Transmission
  • Organic/Inorganic Water Analyses
  • General and Wet Chemistry


  • In-situ Electrical Resistivity Testing
  • Grounding System Evaluation
  • Geoprobe™ Soil Sample Collection
  • Onsite Chemical Analyses


  • Duplicate (QA) and Standard (QC) Testing
  • X-Control Plotting
  • Specialized Internal Calculations
