Our Tunneling Expertise encompasses a comprehensive suite of skills, knowledge, and practical experience in the complex art and science of excavating underground passages for a wide spectrum of essential purposes. We provide specialized capabilities in the design, planning, and execution of tunneling projects tailored to meet diverse infrastructural needs, including transportation networks (such as roads and railways), critical utility conduits (for water conveyance and sewage systems), essential hydropower infrastructure (penstocks and tailrace tunnels), and vital access routes for mining operations. Our deep understanding of various tunneling methodologies allows us to select and implement the most appropriate techniques based on site-specific geological conditions, project requirements, environmental considerations, and budgetary constraints.

Our team of seasoned tunneling engineers, geologists, and skilled construction professionals possesses extensive experience in a broad range of tunneling methods. This includes conventional drill and blast techniques, which are particularly suited for hard rock environments, as well as a variety of sophisticated mechanical excavation methods utilizing Tunnel Boring Machines (TBMs). We are proficient in selecting the optimal TBM type – whether it be Earth Pressure Balance (EPB) machines for soft, unstable ground, Slurry Shield TBMs for water-bearing soils, or Hard Rock TBMs for efficient excavation in competent rock – ensuring maximum advance rates and ground stability. Our expertise also extends to the New Austrian Tunneling Method (NATM), a flexible and adaptable approach that utilizes the inherent strength of the surrounding ground for support, often employed in complex geological settings.

Beyond the excavation itself, our Tunneling Expertise includes a thorough understanding and implementation of crucial support systems. We are adept at designing and installing various ground support measures, such as shotcrete linings, rock bolts, steel ribs, and pre-cast concrete segments, to ensure the long-term stability and safety of the tunnel. We also possess significant experience in managing the challenges associated with water ingress, implementing effective dewatering and waterproofing techniques to create a dry and safe working environment. Furthermore, we are committed to minimizing the environmental impact of our tunneling operations, employing strategies for muck disposal, dust control, and vibration mitigation.
