A sheet for waterproof construction is provided to improve durability and lengthen waterproofing service life by uniformly dipping polyurethanes in a sheet when forming a polyurethanes layer. A sheet(100) for waterproof construction comprises an aluminum sheet or a polypropylene sheet(3), and a PE foamed sheet layer(2) and a non-woven fabric(1). In the lower layer of the aluminum sheet or the polypropylene sheet, a concavo-convex part(30) of lattice type is equipped. The PE foamed sheet layer is formed at the upper side of the aluminum sheet or the polypropylene sheet. The PE foamed sheet layer protects the aluminum sheet paper or the polypropylene sheet. The non-woven is formed in the top end of the PE foamed sheet layer. The polyurethanes are uniformly dipped in the waterproof construction by the non-woven. In non-woven, a non-woven extension piece(10) is integrally formed. The non-woven extension piece covers the gap formed in a part where the sheets are contacted to each other. |
