Applying Sprayed Concrete (shotcrete) around the tunnel portal in a tunnelling project in Germany. Shotcrete, a key ground support method in tunnelling, involves spraying a mix of cement, aggregate, and water onto tunnel surfaces. It provides immediate reinforcement, enhances safety, and adapts to irregular surfaces. With quick curing properties and the ability to conform to diverse geological conditions, shotcrete ensures structural stability and accelerates construction schedules in tunnelling
