Belgique – Hopmarkt d’Alost

Aalst Hopmarkt, Belgium

In the Aalst town centre, Soetaert constructed the retaining structures of the first underground parking garage in town. The car park underneath the Hopmarkt offers space for 317 vehicles over three parking levels.

Because of the location of the car park in the town centre, with a lot of local residents and surrounded by historic buildings, it was decided that installation works should be vibration-free.  Using the Cutter Soil Mix technique (CSM), we built a retaining structure for the construction pit, 232 metres long in total and 21 metres deep. In the soft soil mix stretches, steel sheet piling was then inserted as reinforcement, using a non-vibrating method.
