System solutions for the safe and verifiable sealingof steel reinforced concrete jacking pipes

DS Dichtungstechnik GmbH, 48301 Nottuln, Germany

During construction, the penetration of propping agents and lubricants (bentonite) and, if necessary, the escape of compressed air from the pipeline must be prevented.
