Description of the Related Art In recent years, as the number of buildings has been increased in areas where the groundwater level is high, the problem of groundwater seepage in the buildings is inevitable. For this reason, various waterproofing methods have been announced for concrete joints and cracks, and construction results are increasing. When water permeates into a building even though it is originally desired to completely shut off groundwater, as well as when it is necessary to open a hole in the concrete to connect with the outside of the building. There is also.

た。The most prominent one is a grounding wire such as a lightning rod, and such a grounding wire is often connected to a grounding terminal board storage box installed on the basement floor of a building.
In this case, it is the same as the ground wire being used as a water supply for groundwater, so groundwater travels through the ground wire and springs into the building. For this reason, rust occurs on other wiring in the grounding board storage box, the back of the steel door, etc.,
Although it has been a cause of new complaints, there has been no countermeasure against such spring water in the past, and it was difficult to deal with it.
