Abstract
The 2006 ICOLD Bulletin on Geomembrane Sealing System for Dams supersedes and greatly expands upon two earlier versions, published in 1981 and 1991. The 250 dams incorporating geomembranes cited in this new Bulletin include: 174 fill, 43 concrete, 32 roller compacted concrete, and 1 hybrid. Of the total, 115 (46 %) are in Europe, 47 (19 %) are in China, 38 (15 %) are in the United States, and the remaining 50 (20 %) are scattered in other countries and locations. Since most of the experience gained to date is in Europe, the European Working Group on Geomembranes prepared the Bulletin. This article attempts to summarize the 300-page report and is subdivided according to the same chapter structure contained in the Bulletin: materials, testing and durability; loads applied to geomembrane sealing systems (GSS); geomembranes for new and rehabilitated fill dams; geomembranes on concrete, masonry dams; geomembranes for roller-compacted concrete (RCC) dams; special cases; quality control and quality assurance; and guidance on technical content of contracts. Since this Bulletin is a status report of the current state of the practice, there are no recommendations, per se, those being left to readers for their own conclusions.
