WATERPROOF SHEET, WATERPROOF STRUCTURE USING THE SAME, AND WATERPROOF METHOD

摘要

PURPOSE: A waterproof sheet, a waterproof structure using the same, and a waterproofing method thereof are provided to improve reinforcing force using a reinforcement film with excellent tensile strength. CONSTITUTION: A waterproof sheet(10) comprises an asphalt compound layer(12), a reinforcement film(11), and a release film(13). The reinforcement film is formed on the top surface of the asphalt compound layer. The release film is formed on the bottom surface of the asphalt compound layer. The longitudinal and transverse tensile strength of the reinforcement film is 3500-4000N/cm2, and the longitudinal and transverse elongation thereof is 800-900%.
