What is a Berlin-Type Retaining Wall?
A Berlin-type retaining wall is a structure designed to hold back soil or other granular material and stabilize excavation areas during construction work.
Despite the name, Berliner walls are not related to the historic Berlin Wall. Rather, the name comes from the use of this type of retaining wall during the construction of the Berlin subway system.
A Berliner wall is built using tubular piles driven into the ground. Wood planks are then installed between the piles, held in place by brackets, to retain the surrounding soil during construction work. Berliner walls can also be built using H-Beam piles with wooden planks stacked between the piles. In some cases, retaining walls are constructed with concrete slabs, although this method is less popular in Quebec. Depending on the project requirements, a Berlin-type retaining wall may be temporary or permanent.

A Reliable Berliner Wall Installation Process
Berliner wall installation is an efficient method for stabilizing excavation areas and retaining soil during construction work.
Here is our three-step installation process:
- Steel stiffeners are driven into the ground at intervals ranging from 1.5 m to 2.5 m. Installation is done either by driving them into the ground using an excavator or by vibrating the beam into place. They can also be embedded in concrete caissons. The technique used depends on soil conditions, available space, and nearby buildings.
- Wood planks, steel plates, or concrete panels are then installed between the stiffeners.
- 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.
Our installation methods are designed to provide safe and effective soil retention solutions tailored to construction projects in Quebec.
