What's new in CPT Tool

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.

Version 3 New Features

CPT Tool version 3 adds liquefaction analysis, features to enable the Tool's use with English units for the US market, along with significant enhancements requested by our existing users.


  • Support for AGS4 Format
  • Enhanced support for gINT Professional Plus with SQL Server
  • Database schema restructure of project and point level parameters
  • Import of more data file formats: Vertek (ECP), Gregg Drilling / ConeTec (COR) and Datem Neptune (CDF)
  • Faster, multithread calculation. Now the batch calculation will calculate all strokes simultaneously. Using Access the update is queued, and using SQL server strokes are updated simultaneously. The result is the batch calculation is massively faster

Tools and Functions

  • User definable units, allowing for the use of English/Imperial units
  • Correlation summary command, which creates layers based on like properties and calculates average characteristic parameter values for the layers


  • Pile axial capacity
  • Liquefaction factor of safety, cyclic softening of fine material, residual shear strength, lateral displacement and settlement
  • Correlations for fines content, hydraulic conductivity and state parameter
  • Soil Behaviour Types correlations by Begemann (1965), Eslami Fellenius (1997), Ramsey (2002) and Schmertmann (1978)
