For several years already, the sheet pile walls of the tunnels of the Schipdonk Canal and the Leopold Canal in Zeebrugge have been treated against corrosion. Both canals are of great importance for the water management from Flanders to France.
Both tunnels run through largs tunnels. Our government is very aware of the importance of these canals and the tunnels and spare no effort to keep them in good condition.
During the treatment of the sheet pilling, more than half a kilometre deep in one of the tubes, the technicians found old steel cables and some obstacles. Investigation showed that these were remnants of cables that had been used during the construction of the tunnels. These cables have been out of service since then.
SUBMAR was commissioned to trace and remove all these old cables.
