Abstract: Disclosed herein is a method of packing a liquid coating material for building use, which comprises hermetically packing the coating material in one or more flexible inner packs; putting and packing in the resulting inner packs in one solid outer container together. According to this method, the outer container can be recycled after its content was drawn out, and also the amount of the packing material wastes is minimized. Furthermore, this method is suitable for use in a mass packing manner and thus highly economical, and also is an environment-friendly method.

Abstract: The asphalt waterproofing sheet and a joint sealing structure thereof can improve the fire resisting capacity of an asphalt waterproofing layer by the laminating of an aluminum film and a polymer layer on an asphalt sheet thereby to prevent the overheat of a roof structure by reflecting the incident sunlight. Here, the asphalt sheet may allow a release paper to be attached to the bottom surface thereof.

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.
