Micropiles are among the most effective techniques for ground improvement and foundation reinforcement, particularly in sites with limited construction conditions and weak soils, and have been widely used over the past few decades. Depending on subsurface conditions, groundwater level, and loading requirements, micropiles are generally installed using either cast-in-place or driven construction methods. Moreover, in soils with a high groundwater table, where conventional driven micropiles often exhibit limited installation efficiency, barbed micropiles offer a more effective technical solution by providing superior installation performance and improved load-transfer efficiency. In the present study, the concept of barbed micropiles, which is based on the use of barbs attached to the reinforcing bar to enhance mechanical interlocking, improve stress transfer, and increase load-carrying capacity, was implemented experimentally. Accordingly, the pull-out behavior and load-carrying capacity of reinforcing bars used in barbed micropiles embedded in different cemented soil media were experimentally investigated, with particular emphasis on the effects of the surrounding medium, reinforcement type, and specimen diameter. To this end, pull-out tests were performed on cylindrical specimens with dimensions of 15 × 30 cm and 30 × 30 cm prepared in four different media, including cemented sand, cement grout, concrete, and cemented sand after bentonite removal. Furthermore, the effects of reinforcement type (plain and deformed reinforcing bars) and the presence or absence of barbs on bond strength and pull-out capacity were evaluated. The results indicated that the highest bond strength between the reinforcing bar and the surrounding cemented medium was achieved in the concrete specimens. For the 15 × 30 cm specimens reinforced with barbed deformed reinforcing bars, the bond strength reached 6,328 kPa, while the corresponding pull-out capacity was approximately 167 kN. In contra
