Tunneling

We carry out comprehensive tunneling works. We make tunnel connectors - from making openings in the tunnel shoring, excavating along with reinforcing the connector with steel frames and shotcrete, to making the reinforced concrete structure and insulation. Among others, we carried out works during the construction of:

• the tunnel in Świnoujscie under the Świnia River
• tunnel in Gdańsk under the Martwa Wisła River
• subway tunnels of the 1st and 2nd line in Warsaw
