The new ICOLD Bulletin on impervious geomembranes for dams
Geomembranes have been used as waterproofing element in dams since 1959. At present their application includes rehabilitation of all types of dams, and new construction of RCC (roller compacted concrete) and fill dams. ICOLD (International Commission on Large Dams) has dedicated two theme bulletins to the use of geomembranes in dams, one in 1981 (Bulletin 38) and one in 1991 (Bulletin 78). A new bulletin has been prepared by an adhoc European Working Group, under the aegis of the ICOLD Committee on Materials for Fill Dams. The new bulletin, composed of 9 chapters and 3 appendixes, describes the classification and characteristics of geomembranes, discusses the criteria and recommendations for design, construction and operation, and details the application of geomembranes to construction and repair of fill dams, to repair of concrete and masonry dams, to construction of new RCC dams, and to repair of joints and cracks. Underwater repair, quality control, and guidance to technical contents of contracts are also addressed. The paper illustrates the contents of the bulletin, discusses the main issues of the present state-of-the-art, and provides some statistics as emerged from the database.
