CPT Services

Lankelma offer a range of cone penetration testing and other in situ testing techniques. Skilled site operatives perform the testing using top-of-the-range CPT units and equipment.

What is CPT?

The cone penetration test (CPT) involves pushing a cone penetrometer – the cone – on the end of a series of rods, vertically into the ground at a constant rate of 20mm per second, to depths of up to 100m.

Lankelma offer popular piezocone testing, as well as a number of specialist cones that can be run concurrently to test different geological environments and evaluate a range of soil parameters. The CPT platform is also useful for sampling and geotechnical installations.

Why choose CPT?

CPT is ideal for testing a range of soils, measuring in situ stress conditions and shear strength.

  • Fast, efficient and cost-effective data gathering and handling
  • High quality, repeatable results, available in real time, allowing on-site selection of the best locations for testing, sampling and monitoring
  • Low environmental impact: CPT is quiet, with no vibrations and minimal soil disturbance, creating very little waste
  • Fast turnaround on results
  • Data for use in geotechnical/pile design

For more information on cone penetration testing please contact us or view Lankelma’s introduction to CPT video.

Book a bespoke CPT webinar

A great way for you and your team to find out more about CPT and its benefits is a Lankelma webinar.

Tailored to specific needs and experience of CPT, the webinars cover anything from first principles, to specific applications such as railways, contaminated land and nearshore and marine projects.
