T1 - Modified filtration criteria for non-woven geotextiles in landfill construction T2 - 10th International conference on geosynthetics (Proceedings) N2 - The German landfill ordinance includes a certification requirement for geosynthetics used in landfill liner and capping systems. The certification guidelines describe the basis for the design of geosynthetics used in landfill construction. According to the rules which are usually applied, the thickness of the filter geotextile has to be at least 30 times the characteristic opening size O90. Filter geotextiles which are often used in geocomposite drains have a mass per area of 200 g/m² and do not fulfill this requirement. In this paper modified filter criteria for geosynthetics are presented with a particular focus on These geotextile filters in geocomposite drains.
