Özet: Nowadays, reinforcement techniques applied with granular column applications are widely used in increasing soil bearing capacity, preventing liquefaction and providing stability. In this study, polyester encased granular columns and tire encased granular columns were tested under vertical loading without backfill. Deformation behavior and load bearing capacity of granular columns were investigated experimentally and numerically. In this research, the critical behavior of the encasement materials used to prevent the deterioration of column stability under vertical loading has been demonstrated and lower deformations were observed in tire encased columns than polyester encased columns. In other words, the waste tires provide the integrative structure of the backfill material and have played an important role in increasing bearing capacity. This application opens new usage areas for end of life tires in terms of recycling. As a result of the laboratory tests and numerical analyses that showed similar results with these experiments, the tire encased granular columns reached 6 to 12 times more bearing capacity than the polyester encased granular columns
