Entwicklung und Erprobung umweltfreundlicher Injektionsmittel und -verfahren zur Behebung oertlich begrenzter Schaeden und Undichtigkeiten in Kanalisationen unter Beruecksichtigung des Gewaesserschutzes

Abstract

In the year 1983 the overall length of German sewerages was 285.000 km. Although inspections of sewerages didn't happen systematically and on a large scale, estimations assume that 20% of sewerages are damaged. For groundwater protection it is absolutely necessary to repair these damages. The aim of this research project is the test of environmental tolerance of injection materials for sealing leaky sewerages. For this a new test program has to be created and also a general assessment scheme for these materials.
