Frequently Asked Questions

Common questions about excavation services.

What are the common methods used in tunnel construction?
Common tunneling methods include the cut-and-cover method, which involves excavating a trench and covering it with a roof, and the tunnel boring machine (TBM) method, which uses a colossal machine specifically designed to bore tunnels through the earth. Other techniques include drill and blast, as well as the New Austrian Tunneling Method (NATM) that utilizes rock stability for tunnel support.
