1. A method for layer-by-layer filling and compaction of cohesive building materials, in particular of cohesive soil building materials, in at least one borehole near a surface, the method comprising:
introducing the cohesive building material into the at least one borehole; and
compacting the cohesive building material layer-by-layer using a conveying device including a push chain drive and a stuffing piston driven by means of the push chain drive.
