In a building, particularly a building having a concrete wall surface, dew condensation often occurs due to a temperature difference between the inside and outside of a room, which is a problem in terms of habitability or durability of the building. Particularly in the basement, there are more serious problems such as water penetration from outside and water leakage due to cracks. Conventionally, as a countermeasure for these problems, a heat insulating material made of a resin foam plate is attached to the inner surface of the concrete wall on the ground floor. However, in a basement, this is not enough. For example, the construction shown in FIG. 3 is used to prevent the effects of condensation or water leakage.
