CONCRETE WATER PROOF CONSTRUCTING METHOD USING EXHAUSTING TAPE

The present invention relates to a concrete waterproofing construction method using gas removal tape, and more particularly to a concrete waterproofing construction method using gas removal tape wherein the gas removal tape(punched at regular intervals) is attached in a lattice structure for constructing sheet waterproofing agent or film waterproofing agent after coating with primer so as to effectively scatter or discharge water vapor pressure to the outside. The present invention is composed of a primer layer, an adhesive layer on the lower surface of a release film layer, a gas removal tape layer in a lattice structure, punched at regular intervals, and a waterproofing layer on the upper part of the gas removal tape. The release film layer of the gas removal tape forming the gas removal tape layer comprises: PET, PVC, Teflon, PE and PI films. The adhesive layer of the gas removal tape comprises: 33-43 weight% of butyl acrylate; 35-45 weight% of ethyl acrylate; 5-15 weight% of acrylic acid; 0.5-1.5 weight% of catalyst; and 0.5-1.5 weight% of surfactant.
