Exploratory work identifies over 100 l/s water ingress in carbonate rocks, indicating complex tunnelling challenges.

Tunnelling faced over 100 l/s water ingress, complicating excavation and leading to planning modifications.
Two large-scale injection screens were installed with 97 and 75 boreholes each, addressing eroded rock instability.
Excavation was executed in 7 m stages, integrating 59 injection wells to minimize ground settlement at each step.
Multiple materials like Portland cement and polyurethane were used for injections, adapting to varying underground conditions.

Bauer et al. (2025) studied this question.
