Abstract	Three natural soils from Tunisia we are studied to assess their suitability for use as a liner for a acid waste disposal site at Gabes. The dominant minerals were palygorskite (soil 1), smectite (soil 2) and illite (soil 3). X-ray diffraction (XRD), grain size, Atterberg limits, permeability (with water and waste solution), consolidation and shear strength tests were undertaken. Soil 2 had the highest Atterberg limits and lowest shear strength, while the permeability of soil 3 increased significantly over time when tested in a simulated leachate. It was concluded that soil 1 from Sebkhat El Maleh-El Mkhachrma was the most suitable.Trois sols naturels de Tunisie ont été étudiés afin d’évaluer leur aptitude à être utilisés comme couverture étanche d’un site de stockage de dépôts acides près de Gabès. Les minéraux dominants dans ces sols étaient représentés par une palygorskite (sol 1), une smectite (sol 2) et une illite (sol 3). La diffraction RX (DRX), l’analyse granulométrique, la détermination des limites d’Atterberg, la mesure de perméabilité (à l’eau et avec la solution issue des produits de stockage), les essais de consolidation et de résistance au cisaillement ont été réalisés. Le sol 2 présentait les plus fortes limites d’Atterberg et les plus faibles résistances au cisaillement. La perméabilité du sol 3 augmentait significativement avec le temps lorsque le test était réalisé avec un lixiviat reconstitué. Il a été conclu que le sol 1 de Sebkhat El Maleh-El Mkhachrma était le plus adéquat.
