Underground construction jobsite:  We feel at home.
Underground construction for purposes such as road tunnels, railway tunnels, metro and utility tunnels are subjected to severe stress from nature. They require construction systems able to ensure durability and a constant protection against ground water and environmental exposure. Simultaneously, they must be able to withstand the requirements of different operating modes.

What are the different types of tunnels?

There are three basic types of tunnel construction in common use:
Cut-and-cover tunnel, constructed in a shallow trench and then covered over.
Bored tunnel, constructed in situ, without removing the ground above …
Immersed tube tunnel, sunk into a body of water and laid on or buried just under its bed.
