The Clem7 Tunnel, a 6.8km tunnel that lies 60 metres underneath the city’s river, opened for operation in March 2010.  It links five major roads in Brisbane and consists of 308,000 tonnes of concrete tiles, 192 kilometres of electrical cable, 120 jet fans, 166 emergency phones and about 2000 lights.

Although Turbo Seal was not the chosen waterproofing product initially, The Re-Systems Group was called in to stop all leaks in the tunnel, especially at the tunnel’s 75 plus joint areas using our Turbo Seal U injection waterproofing system.

Some of the leak issues inside the tunnel.

Turob Seal being injected on the positive side and getting counterflow.  The wall areas injected now have a fully restored waterproofing membrane.
