Description of works
This
project required all of the knowledge of experienced waterproofing engineers
and technicians. One year of planning prior to commencement ensured that
the client and its consultants had adequate input into the methods used
on the project. The system for injection and the high performance acrylic
and polyurethane grouts were designed by EPTEC with the assistance of
overseas experts.
The leading edge system for injection was successfully reinstated the
existing damaged membrane without excavation or demolition. The works
were completed at night without closure of the tunnel making traffic management
a key component to site works.
