Use of geomembranes for hydraulic concrete works

Abstract

Geomembranes offer numerous advantages for concrete works waterproofing mainly in the following cases: works in seismic areas, concrete designed not waterproof, renewal of works with active cracks. This paper presents the new French regulation (Fascicule 74, Edition 1998). Some case histories are also studied, to point out the main elements to be considered during design and construction. Those points are used by a working group of the French Geosynthetics Committee (CFG) to write guidelines fort use geomembrane to waterproof concrete works.
