AIR PERMEABLE SHEET FOR WATERPROOF REPAIR METHOD AND WATERPROOF REPAIR METHOD USING THE SAME
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.
【課題】従来の改修工法は通気性のない材料で窪みを埋めるために、水蒸気の出口を塞いでしまい、フクレの発生を完全に防止できず、経時変化により、再度フクレが発生するという問題点があった。本発明は、上記従来の改修工法の問題点を改良するべく、膨れ現象が発生しない防水改修工法用通気シートとそれを用いた防水改修工法を提供することを課題とする。【解決手段】上層から下層に向けて、フィルム層（１）、織布または不織布層（２）、粘着層（３）、離型フィルム（４）の順に接合されたシートであって、該シートの断面方向に通気孔（５）を有することを特徴とする防水改修工法用通気シートおよび防水層の改修に際し、防水層のフクレ部を除去した窪みに、該防水改修工法用通気シートから離型フィルム（４）を外して前記窪みに貼付し、その上に塗膜防水層を形成することを特徴とする防水改修工法。【選択図】図１
