14. Quantification of flow rates through virgin and exposed geomembranes and multicomponent geosynthetic clay liners
By N. Touze-Foltz
https://hal.archives-ouvertes.fr/hal-01181134
An experimental device was developed which gave rise to a European standard, EN 14150. This standard is used in CE marking to quantify the flow rates of virgin geomembranes during the manufacturing process. The principle of the test consists in applying a 100kPa water head difference between both sides of a flat geomembrane. Recently, this device was also used to quantify the flow rates of exposed geomembranes HDPE, EPDM, PVC and bituminous geomembranes. The objective of the paper will be to show the results obtained for virgin geomembranes first and then to validate the use of the device from EN 14150 for testing geomembranes up to 30 years after installation to check if they are still ensuring the watertightness function.
