Tunnelling

We support tunnelling operations with advanced, custom-built life support systems and pressurised personnel locks that ensure safety and efficiency in underground compressed air environments. Whether it's access to pressurised work zones, support for hyperbaric interventions, or standby decompression capabilities – we understand the unique demands of tunnel construction.

From small-diameter TBM (tunnel boring machine) access locks to large-capacity multi-compartment systems, our solutions are designed to meet your exact operational profile. With a modular approach and robust engineering, we deliver reliable systems ready for the harsh conditions of the tunnelling world.

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.

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.

Let's build your next tunnelling life support system—together.
