HONG KONG, China–Trelleborg A.B. is making it easier to travel between Kowloon and Hong Kong Island.
The company's marine and infrastructure operation has supplied tunnel sealing systems for the immersed tunnel section of Hong Kong's new Sha Tin to Central Link project.
Hong Kong's Mass Transit Railway Corp is handling construction.
The line, which partly opened in February, includes more than 1 mile of immersed tunnel section in Hong Kong's Victoria Harbor. Trelleborg supplied two sealing systems for the project, the Swedish supplier said June 3.
Trelleborg provided its Gina gasket, which is able to withstand extreme pressure to prevent leakage, as well as its Omega seal, which serves as a secondary safety seal and can endure severe ground movements.
Trelleborg's sealing systems were easy to install when connecting 5,445 feet of the tunnel's concrete panels, according to John McLeod, the project director at contractor company Pinta-Ocean China State Joint Venture. Gina gaskets, he said, are made of a softer rubber compared to other sealing systems available on the market, allowing them to be closed more easily upon initial compression.
