Liège Guillemins railway station

Realization of a retaining wall to secure the new train station.

Technical specifications

Pile wall made of secant rotary cased bored piles

  • Ø 1500 mm

  • embedded in the limestone

with 4 rows of heavy tie-backs

Retaining the hill

The station, designed by Santiago Calatrava, reaches a height of 40 metres and, with its two awnings, a width of 150 meters. Opened in 2009, it took over ten years to build due to the need to keep it operational during the construction work.

In order to secure this 'cathedral of the modern age', we realized secant cased bored piles for the retainment of the “Colline de Cointe”.

Our work was completed in 6 months, using 3 machines.
