Abstract	Dans les installations de stockage des dechets, le confinement des dechets est realise grâce a des structures d'etancheite-drainage dont le role est de limiter les transferts de polluants vers le milieu environnant. L'amelioration de la gestion de ces unites de traitement passe par une meilleure connaissance du comportement des materiaux d'etancheite constituant ces barrieres etanches en couverture. Cet article nous presente les principaux resultats obtenus dans le cadre d’une expertise du fonctionnement hydraulique d'une couverture constituee de geosynthetique bentonitique. / Six geosynthetic clay liner (GCL) samples were excavated from the cover of a landfill site closed since 2002 in order to analyse if an evolution of the chemical and hydraulic properties of the GCL had occurred after maximum 6 years. This question arised in relation with an important leachate production. Results obtained on the GCL show a poor hydraulic behaviour in relation with a low confining stress, cation exchange and the presence of cracks in the bentonite. Those results are consistent with previous results from the literature. With the actual properties measured, water balance calculated helps explaining the increased production of leachate and argue about the generalization of results to the entire cover of the site.
