Understanding Cone Penetrometer Testing (CPT)

Cone Penetrometer Testing (CPT) is an indispensable tool for revealing key geotechnical engineering properties and intricately mapping soil layers or stratigraphy. Celebrated as one of the most widely accepted techniques for soil investigation worldwide, it serves as a cornerstone for geotechnical testing in Hamilton.

The process involves the deployment of a cone penetrometer, pushed into the soil at a consistent penetration rate of 20 mm/s by a series of push rods. As the test progresses, periodic measurements are captured every 20 cm of penetration, offering valuable data points like cone penetration resistance or tip resistance (QC), total penetration resistance, and possibly sleeve friction (fs). These essential metrics are recorded with high-precision sensors placed at ground level, ensuring the accuracy and reliability synonymous with CPT and geotechnical testing services offered in Hamilton.

By leveraging our advanced TG63 Pagani CPT rig, Ground Testing NZ elevates the standard for CPT Hamilton, delivering results you can trust for your most critical projects.
