In this article discusses the reinforcement of overlap with prefabricated reinforcement meshes instead of individual reinforcement rods. The author's task was to demonstrate the rationale and benefits of using a reinforcing mesh in construction. To determine an effective method of reinforcement the slab of 15th floor of 20- storey building was calculated with the program SCAD. The number of reinforcement and their placement in the two versions of reinforcement: individual bars and with prefabricated meshes were determined. The results of research show the most effective methods of reinforcement.
