Cone Penetration Testing

Cone Penetration Testing (CPT) uses a cylindrical cone pushed vertically into the ground at a constant penetration rate of 20mm per second.

During penetration, measurements are made of the cone resistance, the side friction against the cylindrical shaft, and, in Piezocone Tests, the pore water pressure generated at penetration by the cone.

The measurements are made and recorded using electrical devices. The frequency of the reading provides a detailed picture of the variation of the measured parameters with penetration depth.

Cone Penetration Testing (CPT) is used to:

  • Determine types of soil
  • Identify materials present
  • Estimate geotechnical parameters
  • Provide results for direct geotechnical design
