Abstract
The use of drainage geocomposites in landfill final covers facilitates surface water drainage, contributing to long-term stability. However, validating their durability beyond accelerated laboratory aging tests remains a challenge. The most direct method involves exhuming geocomposites after prolonged field exposure and analyzing their mechanical and hydraulic properties. This study presents two case studies involving multi-linear drainage geocomposites installed in landfill final covers, one exhumed after 10 years in France and the other after 12 years in Canada. The samples underwent laboratory analysis to compare residual properties with original specifications, providing insights into long-term performance.
