Land Services

We offer a range of cone penetration testing and other in situ testing techniques. Our skilled site operatives perform the testing using our top-of-the-range CPT units and equipment.

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.

How does CPT work?

We provide 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.

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.
