CPT Tool - Derived Parameters

CPT Tool

The most user-definable Cone Penetration Testing software available.

Work without limits as you define which types of soil data to present in log, fence, cross-section and graph reports.

  • Define correlation formulas and reports
  • 200+ Preconfigured correlations and derivations
  • 600+ customisable log, fence/cross-section and graph reports

CPT Tool places advanced reporting directly in the hands of geotechnical engineers with code-free report definition and an array of formula configurations, analysis and report options unmatched in cone penetration testing.

Speed up soil data interpretation with rich-data visualisation in any situation, adapting reporting output to changing requirements and conditions across projects.
