Quality Assurance & Quality Control Program

Potential leak paths through the Barrier are limited to the sealed joints and therefore the joints are the main focus of the quality control procedures. Pile driving, joint flushing and joint sealing operations are documented for each individual sheet pile.  The sealable cavity is inspected to verify that it is open along its entire length prior to sealing.  Examination by down-hole fibre optic video camera is an option.
