hello, in a structure where a rafter raft foundation is used (50 cm high), the raft reinforcement (not the beam) on both sides of the foundation is unraveled and naturally turns into a reverse pile. in the application, it was passed straight without pleating. According to the technician, we would consider it straight. However, since the base reinforcement density is reduced by half, is it not a mistake? Also, can such a foundation be solved without a pleat?
