<p>PROBLEM TO BE SOLVED: To provide a method for filling gap in a pipe installation place capable of improving waterproof performance. SOLUTION: A through hole 2 is formed in a wall 1 of a building, and a pipe 3 is installed in the through hole 2. This method for filling the gap 4 between an inner surface of the through hole 2 and an outer surface of the pipe 3 is as follows. A grout material 5 is prepared by mixing cement with a waterproof resin. After closing an opening at an outdoor side of the gap 4, the grout material 5 is injected to the back of the gap 4 from an indoor side to fill the gap 4. A waterproof resin 6 is injected to the back of the gap 4 from the indoor side, while the grout material 5 filling the gap 4 is moved to the indoor side by the injecting pressure, the back of the gap 4 is filled with the waterproof resin 6. The grout material 5 is injected to the back of the gap 4 from the indoor side. While the grout material 5 and the waterproof resin 6 filling the gap 4 are moved to the indoor side by the injection pressure, the back of the gap 4 is filled with the grout material 5. The waterproof resin 6 can block off water not to make it enter into an indoor.</p> |
