<p>PROBLEM TO BE SOLVED: To provide an air permeable sheet for a waterproof repair method and the waterproof repair method using the same capable of improving the following problem in a conventional repair method without providing expansion phenomenon: the conventional repairing method having a problem that, since a depression is filled up with an air impermeable material, an outlet of vapor is closed, and generation of expansion is not prevented completely, resulting in that the expansion is generated again by changes in aging.SOLUTION: There are provided: an air permeable sheet for a waterproof repair method in which a film layer (1), a woven or nonwoven fabric layer (2), an adhesive layer (3), and a separable film (4) are jointed form upper layer to lower layer in the stated order, and vent holes (5) are formed in a section direction of the sheet; and in the waterproof repair method, when a waterproof layer is repaired, the separable film (4) is separated from the air permeable sheet for a waterproof repair method and pasted on a depression generated by removal of expanded part in the waterproof layer, and a coated film waterproof layer is formed thereon.</p> |
