A waterproof sheet(10) with improved water tightness of joint includes a hook type sheet, and a bottom sheet(11). The hook type sheet includes a base fabric(13) and a pile fabric(14). The pile fabric has hooks made of wrap yarns planted on the base fabric. The bottom sheet is bonded to the base fabric of the hook type sheet integrally. The bottom sheet is waterproof. A loop type joint system(20) includes a base material(21), and a plurality of hooks. The hooks extend from the base material upwards. A plurality of holes(23) is formed on the base material. Waterproof construction using the waterproof sheet and the loop type joint system includes the steps of: removing foreign materials on the surface of a structure; coating the surface with adhesive and waterproof material; installing the waterproof sheet, on which catching rings formed, on adhesive and waterproof material; binding the waterproof sheets with loop type joint system; and spreading liquid coating material on the waterproof sheets and the loop type joint system. |
