We provide innovative and state-of-the-art fiber reinforcement solutions for each step of the existing tunneling construction methods.
> Conventional tunneling
Conventional tunneling is the construction of underground openings using a cyclic construction process. Dramix® steel fiber reinforced concrete is compatible with each step of this construction process: from preliminary lining to final lining (cast-in-situ and spray lining).
> Mechanized tunneling
Mechanized tunneling includes all mechanical excavations. Dramix® steel fiber concrete reinforcement has a 25-year track record of providing robustness and longevity in segmental linings in many projects across the world.
To contain long-term loads (ULS), and obtain optimal crack control (SLS) and durability we recommend different solutions for different requirements:
