Title:	Minimalinvasive Fugensanierung - Laborpraktische Untersuchungen der Injektionsbohrnadel
Abstract:	Dieser Beitrag befasst sich mit der minimalinvasiven Fugensanierung, einer neuen Sanierungsmethode für undichte Fugen mit Fugenbändern. Dabei wird ein neu entwickeltes Sanierungswerkzeug (“Injektionsbohrnadel”) durch die Fugendichtung gebohrt, über welches im Anschluss eine Dichtmittelinjektion erfolgen kann. In einem Forschungsprojekt wurden dabei diverse Untersuchungen mit Injektionsbohrnadeln an verschiedenen Fugenarten und Fugenbändern durchgeführt. Nachfolgend wird ein kurzer Überblick über die durchgeführten Untersuchungen sowie ermittelte Chancen und Risiken der Injektionsbohrnadeln für die verschiedenen Anwendungsgebiete dargelegt. Minimal invasive joint restoration - Laboratory testing of the injection drilling needle This paper deals with minimally invasive joint renovation, a new method of repairing leaking joints with joint tapes. A newly developed renovation tool (“injection drilling needle”) is drilled through the joint sealing and can then be used to inject a sealant. In a research project, various tests of the injection drilling needle were carried out on different joint types and joint tapes. The following is a short overview of the investigations carried out as well as the opportunities and risks determined for the injection drilling needles for the various areas of application.
