High standards
Our systems are designed with durability and user comfort in mind, even in the harshest working conditions. Pressure chambers and locks feature intuitive controls, easy access, and are built with materials resistant to corrosion, impact and extreme temperatures. We ensure the integration of ergonomic layouts, minimal maintenance needs and seamless interfacing with other site systems.
Safety
Safety, reliability and quality is the foundation of everything we build. All systems are engineered with redundancy in critical systems, emergency bypass functionality and real-time environmental monitoring. From fire-resistant interior panels to safe gas delivery systems and automatic pressure controls — every detail contributes to protecting lives in high-risk tunnelling environments.
