METHOD FOR PARTIAL ATTACHMENT WATERPROOFING ON A VERTICAL OR HORIZONTAL PLANE OF CONSTRUCTION CONTINUOUSLY, WITH QUICK SPRAY TYPE LIQUID MEMBRANE

A waterproof layer construction method in a concrete structure using quick stiffness coating waterproof material is provided to prevent local stress generated due to crack, the change of external temperature, and the variation of load from being delivered to a waterproof layer. A waterproof layer construction method in a concrete structure using quick stiffness coating waterproof material comprises following steps. A waterproof base material is set up(S100). After foreign material on the surface of a vertical member and a ceiling member which are adjacent to the inner side of the end of the waterproof base material is removed, the surface is roughly treated(S200). The treated surface is coated with adhesion solution(S300). The surface is coated with mixed adhesion solution in which adhesion solution and cement are mixed(S400). A waterproof layer is formed by successively spaying quick stiffness coating waterproof material on the part in which waterproof base material and the mixed adhesion solution are coated(S500). The waterproof layer is finished through a brush, roller, or spray(S600). The coating waterproof material is hardened within 10~30 seconds after spraying.
