Self-supporting and frameless device used as protection against floodwater comprises a modular system consisting of self-supporting rigid containers (1) filled with liquid, heavy objects and/or sand and having an outer periphery providing various connecting possibilities which are joined together in a sealing manner to form an artificial dam. Preferred Features: The containers are cylindrical and the connection possibilities on the periphery are arranged at 60degrees to each other to allow construction of different dam guides and positioning of the containers in a honeycomb-like arrangement.
