Quay wall stabilisation

The most urgent intervention of the Antwerp Scheldt Quay Project is the stabilisation of the quay wall. Without these safety works, it would not be advisable to elevate the water barrier and redevelop this public domain.

As early as 1883, engineers noticed that parts of the quay wall had shifted toward the Scheldt. This precarious balance was caused by the Boom clay under the wall's foundation and the pressure from the groundwater. Throughout the past 130 years, structural engineers have developed various solutions, yet each of these has proven to be inadequate. In the framework of the Sigma Plan, De Vlaamse Waterweg nv is working on a definitive solution for the unstable quay wall.

Cracks in the wall Sinking of the quay surface Crumbling of the quay wall

We are investigating, within each zone, how best to renovate the quay wall. In the Sint-Andries and Het Zuid zones, for example, we have decided on a ‘soft renovation’ to reinforce the wall for the coming 100 years. The quay wall in the Nieuw Zuid zone is in the worst condition. The unstable wall there was no longer safe and had to be urgently replaced by a new, sturdier construction. Nieuw Zuid is the only zone where we will completely demolish the old quay wall and rebuild it.

The various steps involved in this work at the Sint-Andries and Het Zuid and the Nieuw Zuid zones are outlined here.

Steps in stabilising the quay wall

To repair the quay wall and, at the same time, prepare for the future, we will implement a sustainable and innovative technique per zone. The beauty of this approach is that it preserves the authentic character of the quay wall.
