Preferred Components: In (I), an insulator or an insulating jacket is provided for the electrical insulation of the grid structure electrode against an electric conductive surface of the building structures. The counter electrode is a grid- or flat band electrode. A photovoltaic or other regenerative powder is fed into the direct current source. The device is provided in an optional temporary repair mode for the damaged areas of the grid structure electrode with a circuit of the grid structure electrode as a cathode and with the adjustment of the direct current source, where an accretion of hard aragonite occurs for the protection of the damaged areas due to the production of the current density at the grid structure electrode connected as cathode. |
