APPLIANCE FOR PREVENTING WATER USING WATER PROOFING MATERIAL AND IMPROVED SHEET HAVING HOLE

摘要

PURPOSE: A waterproof structure which couples an improved drilled sheet and a waterproof material is provided to improve work efficiency by reducing working time, and to maintain a uniform thickness of the sheet. CONSTITUTION: A waterproof structure which couples an improved drilled sheet and a waterproof material comprises a waterproof primer(10), a first waterproof material(20), an improved drilled waterproof sheet(30), a second waterproof material(40), stone color(50), and paint(60). The waterproof primer is spread on a concrete floor material(C) of a rooftop, an underground parking lot, and an underground structure. The first waterproof material is spread on the top of the waterproof primer. The improved drilled waterproof sheet comprises bubble holes(31) drilled at equal intervals and is attached on the top of the first waterproof material. The second waterproof material is spread on the top of the improved drilled waterproof sheet. The stone color is spread on the top of the second waterproof material for preventing slipping. The paint is spread on the top of the stone color and prevents the stone color from being discolored.
