TY - JOUR A1 - Seeger, Stefan A1 - Müller, Werner T1 - Requirements and Testing of Protective Layer Systems for Geomembranes JF - Geotextiles and Geomembranes N2 - Geomembranes used in basal liner systems of landfills must not be damaged by the coarse gravel of the standard drainage layer. Therefore, the geomembrane must be protected against mechanical damage and strain by means of a suitable protective layer. The main requirements for this protective layer as well as the long-term durability of the mineral and geotextile components are compiled in the guideline recently released by German authorities. An overview is given on the existing types of protective layer systems with the state-of-the-art testing, the requirements and selected results of related research programs.
