CONTINUOUS CORING – Geo Consult

Continuous coring perforations represent the only “direct” method of investigation in the context of the diagnosis of non-invasive techniques, because the withdrawn soil sample has an infinitesimal size compared to the extension of the survey area. As far as possible, soils coring must be a dry coring performed with a 10 cm diameter corer.

Mud Stabilised Drilling: Continuous Core Drilling ...

Continuous Core Drilling: A continuous core sample is obtained using a diamond tipped core barrel. Provided full core recovery is achieved (which is not always possible in very low strength rocks and granular soils), this technique provides a very reliable (but relatively expensive) method of investigation.
