PROBLEM TO BE SOLVED: To provide waterproofed concrete whose concrete itself is watertight and has a waterproofing function in combination, and which is excellent in development of strength, durability, and cost effectiveness, respectively, and an inorganic system waterproofing construction method for buildings. SOLUTION: Since a non-air-entraining agent 11 is employed as a water reducing agent, the air bubbles generated in the concrete are decreased. Consequently, the concrete itself is made watertight and is enhanced in waterproofness. Also, metallic fibers 12 for reinforcement are added into the concrete and therefore even if the expansion crack by initial heat of hydration and drying shrinkage crack tend to be caused in the concrete, the expansion of the crack can be suppressed by the bonding strength of the metallic fibers 12 for reinforcement existing in the cracked portion 12. As a result, the waterproofed concrete itself is watertight and has the waterproofing function in combination, and can enhance the development of the strength, the durability, and the cost effectiveness.
