Assessment of 10 years of use of geosynthetic sealing devices in French navigable canals

Abstract

Sealing devices using geomembranes and similar products have been implemented over the last ten years in the rehabilitation of navigable canals. This article describes seven examples, in the north and east of France, six using bituminous geomembranes and one a bentonite synthetic material. The support structures are very different. On the other hand, the protective structure, consisting of concrete slabs cast in situ, is identical at the six sites using a geomembrane.
