It is very important to evaluate the industrial wastes, which have the potential to be reused with new alternative methods. Treatment plant sludges and fly ash are industrial wastes known to have the potential for beneficial reuse. The useful reuse of these industrial wastes will contribute to the economic development of the organizations and the country by reducing environmental pollution, reducing storage costs, reducing the use of limited natural resources and providing new generation materials. The geological origins of the ground and rock environments on which the structure is constructed have a very variable structure and different types of geological materials require different solutions in terms of design. Conventional foundation construction methods are expensive and lose their economy in the buildings to be constructed in areas with poor ground conditions. In recent years, due to the high cost of construction with traditional methods, the numerous problems caused by environmental factors and the difficulties in overcoming them, the use of on-site soil remediation methods on the poor soil has gained importance. In this study, the impermeability behaviors of sludges and fly ash materials of industrial waste drinking water treatment plant were investigated. Within the scope of the study, drinking water treatment sludge and fly ash were added to sand ground in 2%, 4%, 6%, 8%, 10%, 12%, 14%, 16%, 18%, 20%, 22%. The permeability behavior of the prepared mixtures was investigated with the help of small scale model experiments depending on the contribution rates and time. According to the results obtained, it is observed that both industrial waste materials significantly increase the impermeability of sandy soils. Experimental data indicates s that the increases of up to 106 times when industrial waste materials were added at 2% and up to 1691 times when 22% were added.
