The New Austrian Tunnelling Method, or NATM, is a modern and effective tunnelling technique. It leverages the natural strength of the surrounding rock and is adaptable to various geological conditions. MEIL has incorporated this tunnelling technique to provide last-mile connectivity in multiple projects, including the Zojila Road Tunnel, Char Dham Tunnel and the Tejaji Nagar-Balwara Road Projects. #tunneling #newaustriantunnellingmethod #ZojilaTunnel #tunnelengineering #chardhamrailtunnel #Shotc
