The article examines the filtration properties of gypsum-treated silty sands in soil structures located in flood-prone areas. Special attention is given to the impact of gypsum on filtration characteristics under conditions of high humidity and water saturation. The methods of laboratory testing are described, aimed at assessing the changes in permeability of sands after gypsum application, as well as the influence of rising groundwater on the behavior of filtration processes. The results showed that gypsum-treated silty sands exhibit improved resistance to flooding due to the formation of stable gypsum compounds that reduce particle mobility and enhance structural stability. The article also provides recommendations for using gypsum as an additive to improve the performance of soil structures.
