Sealing walls without supporting elements.
If the space conditions available permit the execution of a supporting embankment or if the aim is to enclose contaminated locations (e.g. landfill sites, industry), sealing walls represent an economic execution variant.
The formula of the sealing wall mass is adapted to the respective requirements. Sealing walls have a minimum wall thickness of 45 cm. The movements of the diaphragm wall grab are, as in other procedures, monitored and electronically recorded during manufacture through inclinometers.
The manufacture takes place in accordance with DIN 4126 or DIN EN 1538 as well as the recommendations by the Excavation Pit Working Group (EAB)-
