Abstract : This paper deals with the recent research results obtained through the SOTREDI project -SOil TREatment for DIkes- undertaken by the Lhoist Group, a World leader in lime production, in collaboration with several research centers and universities. In a first part of the project, it was demonstrated that lime-treated soils could comply with several critical specifications for water retaining structures : low permeability level, mechanical stability, internal and external erosion, reduction of shrinkage risk and dispersive behavior of soils, etc.Real-scale experimental dikes were built in September 2011, to verify the correspondence between lab results and the realscale realization.In parallel, elements about durability of lime-treatment will be reported by examples of more than 30 years old structures around the world.
