DOUBLE-LAYERED WATERPROOFING METHOD AND CONSTRUCTION USING ELASTIC MMA RESIN

摘要

PURPOSE: A method for constructing waterproof layers with double structure using an elastic MMA resin is provided to improve restoring force with respect to tensile and external impact and waterproofing function. CONSTITUTION: A method for constructing waterproof layers with double structure using an elastic MMA resin is as follows. A silicate resin is painted on a concrete base surface(100) to strengthen the concrete surface. Multiple rubberized asphalt sheets(200) are arranged and attached on the concrete base surface where the silicate resin is painted in predetermined gaps to form joint portions. The rubberized asphalt sheets has a silica sand layer and a rubber adhesion layer under the silica sand layer. An MMA resin mixed with a hardening accelerator is painted on the joint portions and a part of the rubberized asphalt sheets that is adjacent to the joint portions in order to form a buffer portion(400) with elasticity, thereby connecting the rubber asphalt sheets each other. A reinforcement layer(500) is formed in the top of the buffer portion by attaching the rubber asphalt sheet corresponding to the size of the buffer portion.
