Soldier pile walls


The most inexpensive vertical excavation pit installation is the soldier pile wall. It is available in different execution versions.

The most well-known of these is the so-called Berlin lining. The name is derived from the first application of this lining in the 1930’s during the construction of the Berlin underground train system. Frequently, the expression Berlin installation is used as a synonym for “soldier pile wall”. Execution variants are the so-called Essen lining and the Hamburg lining.


This lining can be executed everywhere where deformation requirements are low and there is no groundwater above the excavation base.


The girders can be inserted, vibrated or rammed into boreholes. The infill between the girders is to be installed during the course of the excavation work. Depending on the requirements, the intermediate spaces are filled out with wooden planks, steel profiles, prefabricated concrete parts or shotcrete.    

Depending on the building site characteristic values and taking the traffic and structural loads into account, a grouted anchor is necessary for the soldier pile wall. This is generally the case from an excavation pit depth of 2 metres downwards. This grouted anchor can be carried out using ground anchors or bracing to the opposite shoring wall. In the case of deep excavation pits, the soldier pile wall is to be anchored or braced at several levels.  

If there is an economically-favourable possibility to execute the excavation pit with space to work, the girder profiles can also be removed again after completion of the building.


The manufacture of soldier pile walls takes place in accordance with DIN 4124 as well as the recommendations by the Excavation Pit Working Group (EAB).
