Eijkelkamp Compact CPT

Earth Drilling now offers a variety of in-situ geotechnical testing methods including Cone Penetration Testing (CPT). Our digital CPT units have the capability of measuring tip resistance, sleeve friction, pore water pressure and temperature at intervals between 1 and 5 cm to provide a continuous profile of the subsurface soil conditions. The ability to produce a continuous soil profile with detailed accuracy makes the CPT superior to traditional testing methods. This is a cost-effective way to gather more information and has become an industry standard. The data collected in the field is followed up with a project-specific report detailing the site investigation results.

Eijkelkamp Manual Drill’n’CPT Unit

Earth Drilling’s Eijkelkamp Manual Drill’n’CPT Unit is a 20 ton fully automatic CPT tool placed in the breakout clamps of a sonic drill rig. The CPT tool allows you to convert every (sonic) drill rig into a CPT unit. It can deliver a continuous CPT measurement or measure in between sampling. It is also the perfect combination to advance casing through refusal layers and apply CPT testing to greater depths.
