摘要

An elastic reinforcement sheet and a waterproof method using the same are provided to form a waterproof layer of uniform thickness and to improve elasticity and flexibility of the waterproof layer. An elastic reinforcement sheet comprises a bottom sheet(110) made of woven fiber, a support fiber layer(120) in which support fibers are arranged in the vertical direction, a top sheet(130) which is made of woven fiber including fiber beams(132) injection holes(134) between the fiber beams and located to form a waterproof liquid filling space between with the bottom sheet, and a back coating layer(140) which is coated on the whole lower surface of the bottom sheet in order to prevent the infiltration of oil or water into the lower surface of the bottom sheet.
