Utilizing the impressed current system to protect balconies involves laying a titanium anode mesh over the repaired concrete deck, which is then covered with a thin topping or thinset. A tile overlay may be installed over the mesh depending on the owners’ choice of finish. If a tile cover is not desirable, a titanium ribbon mesh can be inserted into saw-cut slots in the balcony deck and filled with a non-shrink cementitious grout.
The concrete surface is then painted or sealed with a waterproof membrane. A power supply (rectifier) is used to convert alternating current (AC) to direct current (DC). The rectifier and associated junction boxes are typically installed in a utility room.
The anode system is connected to the positive pole of the rectifier using wire in conduit and the rebar to the negative pole. More.
