Tunnel construction

Safely
quickly and discreetly

Classic tunnelling is one of the most demanding disciplines in the construction industry. It involves impressive equipment and a complex team of geologists, structural engineers, workers and other specialists.

PORR is one of Europe's leading tunnelling contractors and has all the technical equipment required for tunnelling projects of all kinds, in addition to decades of experience. It doesn't matter whether it is a shaft for pipelines or a tunnel for road, rail or pedestrian traffic - we work in mountainous terrain as well as in densely built-up conurbations and cities.

When building tunnels, we not only ensure the highest quality of workmanship, but also environmental protection, flawless work safety and the health of our employees.
