という欠点もあった。Conventionally, a method of forming a coated urethane resin floor by directly coating a urethane resin on the concrete slab surface for the purpose of waterproofing on the floor surface or rooftop of a concrete building has been adopted. However, in the conventional coated urethane resin floor formed by directly coating urethane resin on the concrete slab surface, when moisture in the concrete is released as water vapor due to the rise in outside temperature, there is no escape of this water vapor. There is a problem that water vapor accumulates between the concrete slab surface and the urethane resin layer, which causes the urethane resin layer to peel off, and the urethane resin layer rises to form irregularities on the surface. Further, in the conventional coated urethane resin floor, when the concrete slab is cracked, the urethane resin layer is also cracked and the waterproof function cannot be achieved.
