Abstract
A hybrid waterproofing structure and a construction method therefor are provided to prevent water leak on a housetop or roof, in which the structure is improved to take merits of an asphalt sheet and a coating waterproof material and supplement demerits thereof. The hybrid waterproofing structure includes a waterproof sheet in which the edges of connection portions keep a predetermined distance from each other, when the waterproof sheets are laid on the upper surface of a slab layer, where bottom hair roots of a nonwoven fabric are implanted and fused into the upper surface of an asphalt sheet, and upper hair trunks of the nonwoven fabric are protruded externally, and a coating waterproofing layer formed by coating liquid-phase coating waterproofing material on the upper surface of the waterproof sheet.
