Summary:PROBLEM TO BE SOLVED: To provide a water-cutoff wall with high mechanical strength for covering a deep underground concrete wall.SOLUTION: A mixture containing unvulcanized butyl rubber, filler, and plasticizer, wherein the unvulcanized butyl rubber of 15-25 wt.%, the filler of 60-70 wt.%, and the plasticizer of the remaining percentage are mixing, is mixed with solvent and applied on a reinforced sheet 16. A rubber mixture layer 18 is adhered on the reinforced sheet 16, while having the solvent vaporized, so as to form the rubber mixture layer 18 with a membrane of higher percentage of the filler on the outer surface part than inside. Then a concrete formwork 32 is constructed on the outer surface side of the rubber mixture layer 18 and ready-mixed concrete is poured into the concrete formwork 32 and hardened to form a concrete wall 14. The reinforced sheet 16 and the concrete wall 14 are adhered and integrated with each other through the rubber mixture layer 18.
