Client: Coffey Geotechnics

Brief: Undertake multiple CPTu tests up to 40m deep, through the sea wall to determine subsurface geophysical conditions for the wall design.

Constraints: Very tight time constraints to work within.

Site description: Upon completion of the testing the two kilometre long sea wall was covered by the sea as the tide rose thereby cutting of the only means of returning to the mainland.
Service: Testing was completed at night and as the wall was being inundated. It was only possible to know where to drive by the white water rushing over the wall.
