PROBLEM TO BE SOLVED: To provide a water seal construction and a method for stopping water capable of definitely stopping the leakage of grout at the outlet portion of a saddle in an extra-doused bridge or the like and of offering excellent workability. SOLUTION: This is a water stopping construction at the outlet portion of a bridge saddle in which a plurality of tension members are arranged and inserted through a pipe and grout is filled between the pipe 4. At the outlet portion of the pipe 4, spacers 20 arranging each tension member at the predetermined intervals are installed. From these spacers 20, a retaining plate 30, an elastic member 50 and a pushing plate 60 are sequentially arranged toward outer side. There is a filling portion for a resin 40 between the retaining plate 30 and the tension member. And the elastic member 50 is compressed and deformed between the retaining plate 30 and the pushing plate 60, thereby sealing the gap between the elastic member 50 and the tension member and stopping the leakage of the resin filled in the retaining plate.
