Drilling is used, among other things, to produce cast-in-place piles, to install precast concrete or steel elements or to loosen the building ground for subsequent pile driving work.

Pile driving methods are used to insert elements such as piles or sheet pile walls into the ground. Thus, foundation piles or cut-off walls are produced.

Slurry wall work creates panel-shaped excavations in the ground which are then filled with concrete. These elements serve, for instance, as foundation elements or cut-off walls.

Soil improvement methods are applied to improve the natural properties of the building ground by working the soil or adding binding agents.
