Description of the invention: - [Technical field to which the invention pertains] The present invention relates to a method for water cut-off and water leakage prevention of an existing building roof, in particular, a water (or a parapet wall) that can effectively eliminate the roof of an adjacent house. Water leakage from the roof of the house, etc., flows into the roof of the house, so that the waterproof protective layer on the roof can achieve the water leakage prevention and leakage prevention method of the existing building. [Prior Art] When there is water leakage on the roof, the current repair method has: (1) After the old waterproof layer is removed and reapplied as a waterproof layer, it is covered with a protective layer. However, this secret method is more time-consuming and labor-intensive and does not meet economic benefits. • (b) As shown in Figure 1, it is attached to the existing roof slab 11 and the old waterproof layer 12 and its protective layer 13 (such as blister cement) are removed. However, it is difficult to remove the water contained in the old protective layer 13 by the repairing method, resulting in a leak-proof effect. In addition, the above two repair methods only repair the roof slab u of the home, and in the case that the adjacent roof slab 14 is not repaired together, the water sluice 15 will infiltrate from the cover protective layer 13 of the adjacent roof slab 14 After the roof of the house, it flows again and falls under the waterproof layer 16 of the new work of the house, causing the new waterproofing project to fail and the waterproof effect to be lost. In addition, if the watertightness of the parapet wall or the eaves itself on the roof slab 11 is insufficient, it may also cause water to flow into the new waterproof layer below the house due to water seepage, resulting in loss of waterproofing effect. Therefore, at present, the most effective treatment mode is to select all the eradication, or to partially remove and apply the water cut section. The traditional water cut area method partially removes the original cover protective layer 13 near the periphery. After the original floor slab, and then applied as a waterproof layer, in order to achieve the function of water cut, but this 5 201013028 - construction method, because the original waterproof layer 12 and its protective layer i3 must be removed, it will still cause the house The length of the voice and the application time will be lengthened. If it is not repaired in time, the water leakage caused by the rain will increase. It can be seen that there are still many shortcomings in the above-mentioned conventional methods, which is not a good designer, but needs to be improved. In view of the shortcomings derived from the above-mentioned conventional repairing methods, the inventor of the present invention has improved and innovated, and after years of painstaking research, he finally succeeded in researching and developing the roof water cut-off and leakage prevention methods of the existing buildings.
