▎ 摘　　要

NOVELTY - The material has a graphene fiber composite coated with nanocellulose, where part by weight of the graphene fiber coated with nanocellulose in 100 pts. wt of the graphene fiber composite coated with nanocellulose is formed of 2.5 to 3.0. A waterproof upper resin layer (12) is formed on an upper surface of a nanofiber tissue (11) for waterproofing. A waterproof lower resin layer (13) is formed on a bottom surface of the nanofiber tissue. USE - Material for waterproofing a bridge surface or building using a nanofiber tissue. ADVANTAGE - The material can maintain airtightness by installing a waterproof sheet on the bridge surface or structure i.e. building, so that the asphalt concrete layer is prevented from vehicle passage or external force, thus preventing distortion and damage to the bridge surface by preventing deformation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for waterproofing a bridge surface or building using a nanofiber tissue. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of a nanofiber tissue layer.
