摘要
A waterproof constructing method using dual waterproof sheets and a waterproof structure are provided to reduce material cost by securing the waterproof structure having excellent tension resistive force and joining the joint part of first waterproof sheets by a butyl rubber adhesive sheet. A waterproof structure using dual waterproof sheets(31a,31b,31c,31d) comprises a first waterproof layer contacted with plural first waterproof sheets(11a,11b,11c,11d); a jointing adhesive sheet(21) attached at the contacted jointed part of the first waterproof sheets to hold airtightness; a second waterproof layer hinge-connected with the second waterproof sheets attached with a surface reinforcing material on the improved asphalt layer surface and closely contacted by heat-welded on the first waterproof layer; and a push layer formed at the upper surface of the second waterproof layer.
