PROBLEM TO BE SOLVED: To improve workability by firmly fixing a waterproof sheet to a waterproof construction surface so as to be capable of sufficiently resisting wind pressure, and reducing an installation ratio of fixing members when the waterproof sheet is fixed and laid on the water construction surface by fixing members.SOLUTION: In a waterproof construction method for fixing at least one waterproof sheet on a construction surface by a plurality of fixing members, the required minimum installation ratio M of the fixing members on the construction surface is represented by formula (1): M<X*Y/Z (1) (wherein, X represents a wind pressure on the construction surface (N/m); Y represents a safety factor (%); and Z represents a number of 2,000 or less (N/m)). |
