What is a Berlin-Type Retaining Wall?

A Berlin-type retaining wall is a specific type of structure used to hold back soil or other granular material when you're doing construction work.

Interestingly, the name has nothing to do with the Berlin Wall! Rather, the name comes from the fact that this type of retaining wall was used during the construction of the Berlin subway system.

A Berliner wall is made of tubular piles driven into the ground. Between these piles are planks held in place by angle brackets. In this way, the soil remains in place during construction work. Berliner walls can also be built using H-Beam piles, with wooden slabs stacked between the piles. It's also possible to build a retaining wall from concrete slabs, but this method is less popular in Quebec. A Berlin-type retaining wall can be temporary or permanent.

Here's how to install a Berliner wall, in three steps

  1. Stiffeners are driven in the ground, with a distance of 1.5 m to 2.5 m between each one. They are installed by ramming with a mechanical shovel or by vibrating the truss. They can also be set in a concrete drum. The technique used depends on the type of soil, the space available and the buildings around the site.
  2. Then wood planks, steel plates or concrete panels are installed between the stiffeners.
  3. Where necessary, excavation is performed in stages, leaving a gap of 1 to 2.6 m, depending on the terrain. If the depth exceeds 3 m, anchors can be used to reinforce the wall.
