Due to the low hydraulic slope of the Kizilirmak River, the water flow rate is slow. For this reason, mostly fine-grained materials are transported and stored. Since the foundation rock is at lower altitudes, the building foundations near Kizilirmak River are mostly built on fine-grained material. Structural foundations that are not constructed mostly according to the Basic Engineering criteria, cannot exhibit solid-rigid behavior if exposed to excessive water effects in events such as precipitations and riverbed flood. If the drainage conditions are not provided, the negativity increases even more. In this case, the fine-grained base material saturated with water shows more plastic behavior. Due to the plastic behavior, the building's foundation and walls lose their primary feature and are caused to cracks, decomposition and then deformations. In this study, soil material parameters and drainage conditions are tried to be explained in laboratory conditions for the deformations on the structures in the village of Karabucak near the Kizilirmak river. In case of interaction of fine-grained cohesion materials with water and drainage conditions are not met, it was observed that the pore pressure increased when the liquid limit exceeded 50%. In cases where the liquid limit exceeds 60% and the plasticity index exceeds 20%, the potential for swelling and compression increases. It has been observed that a high rate of damage occurs in these types of structures due to increasing volume changes up to 13% with increasing swelling pressures. Similarly, in terms of shear strength, it has been determined that there is a loss of stability in cohesion below 20 kpa and internal friction angle below 30
