Innovative sealing products from Trelleborg chosen for the world's longest immersed tunnel

摘要

In October, 2011, Trelleborg Infrastructure signed a contract with China Communications Construction Co. Ltd. for the supply of a tunnel sealing system for the world's longest immersed tunnel. The seals were chosen due to their innovative design that will ensure water-tightness even in case of a seismic event. Part of the prestigious Hong Kong -Zhuhai - Macau link project in China, the immersed tunnel will be approximately six kilometers long and consist of 32 elements.
