The “zero leakage” approach and German regulations for geosynthetics used in landfill liner and capping systems

  • An approach to achieve “zero leakage” is discussed with respect to the experience in Germany, where strict regulations for landfill lining and capping systems have been developed and issued because of large environmental problems related to landfills that accumulated in the 1970’s and 1980’s. These regulations for landfills and geosynthetics which are used in landfill liner and capping systems are shortly described. The main certification requirements for the products as well as conclusions for their use are presented. Using a thick, high quality HDPE geomembrane (GMB), which is installed free of residual waves and wrinkles in intimate contact with a compacted clay liner (CCL) or geosynthetic clay liner (GCL) of very low permeability, by a qualified, experienced, well equipped and properly third‐party controlled installer and which are protected by heavy protection layers designed with respect to long‐term performance of the GMB, may result in a liner or capping system of practicallyAn approach to achieve “zero leakage” is discussed with respect to the experience in Germany, where strict regulations for landfill lining and capping systems have been developed and issued because of large environmental problems related to landfills that accumulated in the 1970’s and 1980’s.

This is demonstrated by analyzing results of measurements obtained from permanently installed leak detection systems in combination with HDPE GMBs.zeige mehrzeige weniger
