In a waterproofing method using a layered-waterproofing sheet with a blank unit on a side and having an asphalt waterproofing layer in the lower side of a reused urethane sheet with a thermoplastic hot-molten resin coating layer, the purpose of the present invention is to provide a waterproofing method using a layered-waterproofing sheet with a blank unit on a side capable of removing minute passages formed on an asphalt waterproofing layer by connecting joining and connecting sides each other; lowering a thermosetting by forming a hot-molten resin coating layer as a medium layer on a reused urethane sheet to prevent degradation due to the oxidation of the reused urethane sheet generated by thermosetting the reused urethane sheet and a sheet at high temperatures to bond the same to each other; maintaining an excellent waterproofing function by forming a strong waterproofing protective layer of a reused synthetic fiber mat on the reused urethane waterproofing layer to prevent dents on the reused urethane sheet and damage to the same due to fracture frequently generated by various kinds of factors during a waterproofing work; and improving the durability and providing a function of preventing shock and vibration of a concrete structure, an insulating function, and a heating function at the same time. |
