Copyright - Geotechdata. The test method consists of pushing an instrumented cone, with the tip facing down, into the ground at a controlled rate controlled between 1. The code is attached to a internal still rode than can run inside a outer hollow rod, which itself is attached to a sleeve. Our capability includes the identification and mapping of: Providing information on ground strata and engineering properties to designers planning foundations for new buildings, structures and highways Geoenvironmental investigations to facilitate the remediation of brownfield sites, where CPT can:

We are able to identify: This approach is widely used to estimate soil type and map variability with depth across a site. In the more elaborate CPT instruments, the cone and the sleeve attached to the outer rod can move separately. Due to its simplicity and efficiency, the cone penetration test is one of the most commonly accepted and used in-situ testing methods in geotechnical investigation worldwide. The cone penetration resistance values can be then correlated to shear strength parameters using proposed empirical curves. The cone penetration test CPT is a common in situ testing method used to determine the geotechnical engineering properties of soils and assessing subsurface stratigraphy.
