Xycrete has been heavily involved in waterproofing the Clem 7
Tunnel. Xycrete was the only company with a full compliment of staff
that had been trained overseas in the injection systems (equipment and
chemicals) used to waterproof the joints in the Clem 7 Tunnel and smoke
stacks.
Once out of the main Clem 7 Tunnel and into the smoke or exhaust
stacks there is no permanent lighting or power, so work was undertaken
with miners lamps and limited portable lighting. We supplied generators
and portable compressors suitable for confined spaces and our staff
worked 60 metres below the Brisbane river 12 hour shifts days and nights
to complete what is a difficult job in an extreme location.
Injection jobs can be difficult as we often don’t know the history
of what is behind the wall or has been used as a base for a podium
garden making waterproofing even more challenging. Because of this and
the range of specialist equipments and chemicals available it is
important to use only qualified professional water proofers to undertake
these jobs.
We are extremly proud of the team at Xycrete and the additional hours and effort they put into finishing the tunnel work.
