PURPOSE: A waterproof structure using a roofing sheet is provided to secure a double-waterproof effect and expand the life span of a waterproof material by crossing and doubly arranging the roofing sheets made from EPDM(Ethylene Propylene Rubber). CONSTITUTION: A waterproof structure for mounting a waterproof material to a roof slab of a building by using a roofing sheet is composed of leveling mortar(20) coating and filling up cracks of the upper part of roof concrete(10); primer coating the upside of the leveling mortar; lower and upper sheets(26,28) attached to the upper part of the primer by bond(24) with crossing bonding parts to overlap each half of the bonding parts, respectively; a sealing material(38) coating to finish both ends of the upper sheet; ultraviolet ray cut-off paint(30) coating the upper sheet finished by the sealing material to cut off ultraviolet rays; and an air tube for discharging air to the atmosphere and a reverse U-shape hose(36) interposed between both sides of the lower sheet.
