VertekCPT: capturing the basics from CPT test results! Sponsored

Knowing what Cone Penetration Testing is and the process of soil testing is only a small fraction compared to the actual interpretation of soil test results. Even though CPT rigs are equipped with automated interpretation programs, test results may not be ready to be read and processed immediately. Read on for the basic information to keep in mind when in the process of CPT test result interpretation!

Starting from the basics, CPT test results are based on the relationship connecting the three main measurements acquired when performing a CPT test: cone bearing, sleeve friction and pore water pressure. Based on these data, fundamental information on the soil conditions and the soil's composition can be extracted and a proper soil classification according to the Unified Soil Classification System (USCS) can be made. 

Additionally, CPT testing can provide information on temperature shifts, water content fluctuations as well as measure many soil and geotechnical parameters.
