After GeoCon’s success on the Gwynt-y-Mor on shore cable route geotechnical site investigation on behalf of a large multi national contractor, GeoCon were invited to supervise a geotechnical site investigation at Barkby Beach, Prestatyn North Wales. The geotechnical site investigation included four boreholes to faciliate the installation of plastic casing for a subsequent geophysical survey to establish the location and depth of an existing sheet piled wall.

The site was located on the beach and the sheet piled wall was anticipated to be located at the bottom of the existing sea defense structure.

The location of the sheet piled wall was required in order to design the input route of an offshore cable coming over from Ireland to provide future electricity to parts of North Wales.
