摘要

The device comprises an empty annular space (20), which is formed around a lifting element (1). The annular space is limited by an exterior seal (7) made of plastic or rubber, which directly or indirectly produces the sealing between a base plate (5) and a foundation element (2). A filling line (10) is provided, which flows into the annular space. An independent claim is also included for a method for lifting a base plate corresponding to a foundation element.
