摘要

PURPOSE: An exposure waterproofing method using an acryl based membrane material and a thin waterproof sheet and a waterproof layer structure using the method are provided to reduce construction and production costs by using a thin waterproof sheet instead of a thick waterproof sheet. CONSTITUTION: An exposure waterproofing method using an acryl based membrane material and a thin waterproof sheet is as follows. Asphalt membrane type primer having polystyrene butadiene styrene rubber is spread on concrete. An asphalt waterproof sheet is attached on the asphalt membrane type primer. Acryl primer is spread on the attached asphalt waterproof sheet. A water-soluble acryl based membrane material is spread on the acryl primer. An acryl based coating material is spread on the water-soluble acryl based membrane material.
