A WATER PROOF EXECUTION METHOD OF THE CONSTRUCTION STRUCTURE

摘要

PURPOSE: A waterproofing method of a construction structure is provided to improve the reliability of a waterproof layer by minimizing the separation and delamination of a joint part of a waterproof sheet and by preventing the generation of wrinkle or bending in the waterproof sheet. CONSTITUTION: A waterproof method of a construction structure comprises a step of generating a cutting groove(30) on the surface of the structure in a regular interval; a step of coating urethane(50) in the upper part of a primer(40) within 10cm of width around the cutting groove; a step of locating a waterproof sheet(10) between the adjacent cutting grooves and impregnating the urethane with a non-woven fabric on both sides of the waterproof sheet; a step of attaching a reinforcing non-woven fabric(20) overlapped in a longitudinal direction in both sides of the waterproof sheet; a step of closely adhering the non-woven fabric to the surface of the structure by pressing a filler(60) to the inside of the cutting groove in which the non-woven fabric is inserted; a step of coating a waterproof coating material(70) in the upper part of the reinforcing non-woven fabric and of forming a joint waterproofing layer by filling the waterproof coating material inside the cutting groove; a step of forming an overall side of a waterproof layer by coating an urethane(80) in an overall side of the waterproof sheet; a step of forming a waterproof protection layer(90) by coating sun block and spraying silica on the upper part of the overall side of the waterproof layer.
