Cone Penetrometer Testing (CPT)

Cone Penetrometer Testing (CPT) is probably the most widely used in-situ geotechnical test worldwide and has an extensive database of published correlations for geotechnical parameters.

In suitable ground conditions, CPTs offer a cost-effective method to supplement conventional borehole and laboratory testing data.

Case Study

CPT Testing Used to Supplement Borehole Data

Following an initial phase of geotechnical investigation, comprising cable percussive boreholes, cone penetration (CPT) testing was undertaken to obtain a greater resolution of data, to confirm the ground and groundwater conditions beneath the site.

The testing caused minimal site disturbance, which was critical, as the site investigation works were being undertaken within the confines of a residential care home. The testing was also rapid, which allowed many locations to be undertaken within a day, meaning that any inconvenience caused to the residents was limited to a single day.

Ruddlesden geotechnical commissioned an international contractor to undertake the testing and provided on site supervision and interpretation of the data, which was ultimately used to inform a foundation options appraisal.
