Amur River Tunnel
Category: Transport, Tunnel
Originally built from 1937 to 1941, the Amur River Tunnel is 7,198 m (4.5 miles) long and lies on the eastern end of the Trans-Siberian Railway in Khabarovsk. The only underwater railway tunnel in Russia, it has been repaired numerous times due to concrete delamination and corrosion problems. Leakages, however, eventually became a major obstacle. During an extensive renovation project, PENETRON crystalline technology was applied to eliminate all leaks.
A full range of PENETRON crystalline materials were applied to the walls of the tunnel to stop the pressure leaks and protect the structure against further damage.
