Unlike traditional concrete building component manufacturing, the proposed method eliminates the need for removable formwork, reduces labor costs, and enables the production of complex geometries efficiently. A method for creating a building component with a concrete layer comprises applying at least one layer of waterproofing material to the base; installing permanent formwork on the base; threading at least one reinforcement bar through the formwork; pouring concrete mixture into the internal space enclosed by the formwork; curing concrete mixture until it reaches the required strength. The invention also discloses a building component produced by the proposed methods.
