WATERPROOF SHEET FOR MECHANICALLY FIXING METHOD AND WATERPROOF STRUCTURE USING THE WATERPROOF SHEET
PROBLEM TO BE SOLVED: To provide a waterproof sheet for mechanically fixing method with little distortion so as not to cause a damage or defect on a part of the waterproof sheet even when load imbalance accumulates.SOLUTION: A waterproof sheet for mechanically fixing method includes a lamination of a base material constituted by warp threads and weft threads and a resin layer. After laminating, the base material is heated at 120°C for 90 minutes. The difference of the heat shrinkage ratio in vertical and horizontal directions is equal to or more than -3.0 and equal to or less than +3.0%.SELECTED DRAWING: Figure 1
【課題】防水シートの機械的固定工法において、荷重の偏りは防水シートの一部にダメージを蓄積してしまい、長期的な不具合のリスクを高める。このため、歪みが少ない防水シートを提供することを目的とする。【解決手段】上記目的を達成するために本発明が講じた手段は、縦糸および横糸で構成された基材と樹脂層とが積層され、積層後の前記基材を１２０℃で９０分間加熱した場合における縦横の加熱収縮率の差が−３．０％以上＋３．０％以下である機械的固定工法用防水シートである。【選択図】図１
