There is. However, in a room with a structure in which the walls are built integrally from the four circumferences of a single waterproof pan, it is only possible to construct a room with an area equivalent to one piece of waterproof pan. It was difficult to construct rooms with waterproof floors, such as kitchens. Therefore, conventionally, after applying a waterproofing agent such as asphalt on the floor of a building, finishing mortar etc. is poured on top of the waterproof layer to form a waterproof floor, and then the base frame material is attached to the building frame. At the same time, a frame made of lightweight section steel or the like is fixed to this base framework material to form the skeleton of the room, and the walls are constructed by fixing prefabricated wall structure panels to the frame with screws, etc. The so-called wet method 1 method was used to construct a room with a waterproof floor.
