Cone Penetration Testing (CPT)
Cone Penetration Testing is a soil investigation technique that was developed some 90 years ago and is now utilised all around the world to establish soil behaviour and soil stratigraphy. Through the use of additional modules, the technique can be used not only for geotechnical investigations, but also for hydrogeological and geo-environmental investigations.
What is CPT?
Cone Penetration Testing is an efficient and rapidly evolving ground investigation technique used to determine soil properties and delineate soil layers. The CPT is an in-situ test, meaning that the data is collected by testing the soil in the ground without the need for sampling, logging and laboratory testing.
During CPT an instrumented cone is pushed into the ground and provides, in real time, three soil parameters: cone tip resistance, sleeve friction and porewater pressure.
The carefully calibrated cones are highly sensitive and able to detect even the smallest changes in soil properties, which would be missed or averaged out in less sensitive ground investigation techniques. This makes CPT data the ideal tool for a wide variety of geotechnical and geohydrological engineering applications.
Royal Eijkelkamp for all your CPT Needs
We can support you at every level of your CPT project. Not only by helping you to define exactly what equipment is needed for your individual project, and supplying you with that equipment, but also by helping develop execution plans for specific project and equipping you with the knowledge required to get the most out of CPT.
Our experts provide theoretical insights into the testing method and the various options, as well as providing practical guidance and training on how to perform CPT in the most efficient manner - whilst ensuring the collection of high quality CPT data.
Royal Eijkelkamp is not just a CPT manufacturer, but a provider and expert on a huge range of geotechnical solutions. This gives us a broader view, and enables us to support your wider geotechnical needs. As a result, we have developed combination tools such as the Drill’n CPT to easily convert a drill rig into a CPT rig.
We have also developed the ground breaking SonicCPT system that allows you to push the CPT through soil layers that regular CPT cannot penetrate. And finally we can lean on our extensive knowledge of soil and water testing sensors to provide you with site investigation solutions that go beyond traditional CPT.
