Title:
Abstract:	Etwa 35 Jahre nach der ersten Anwendung auf einer Baustelle in Deutschland ist das Düsenstrahlverfahren heute im Spezialtiefbau etabliert und gehört zum Portfolio vieler Unternehmen. Für dessen Anwendung gelten DIN EN 12716 als zentrales technisches Regelwerk sowie DIN 18321 für die Regelung technisch/vertraglicher Belange. Erfahrungen aus Streit- und Schadensfällen machen die Fortschreibung und Ergänzung der Regelwerke erforderlich. Der vorliegende Bericht zeigt anhand wesentlicher verfahrensbedingter Zusammenhänge in Beispielen, dass bei der Befolgung der vorliegenden und zukünftigen Regelwerke auch verfahrensspezifische handwerkliche Gesichtspunkte zu beachten sind. On the skilled application of jet grouting. Some 35 years ago jet grouting was introduced on a construction site in Germany for the first time. Ever since then it has become an approved method in special ground engineering and is now being offered and applied by many companies. As to its application DIN EN 12716 refers to the central technical guidelines whereas DIN 18321 deals with the technical and/or contractual issues. Experiences with events of damage and disputes show that the regulations need further updates and supplements. This report explains in examples which process-specific craft aspects have to be observed when applying present and future rules.
