The aim of the present study was to determine the use of geomembranes as a remedial alternative for overcoming the swelling foundation problems encountered in irrigation channels. A finite element analysis was performed and the results indicated that rigid concrete linings could not be used effectively in soils with swelling potential. The use of geomembranes with roughened surfaces was seen to be a viable technical and financial alternative to soil removal and replacement. The geomembrane lining did not require a geotextile buffer to provide additional friction between the concrete slab and the geomembrane. ,’.
