Abstract:
1. A method of waterproof and floor construction by using thixotropic urethane and fabric sheets, comprising the steps of: applying a primer on a base concrete surface to form a primer layer; disposing waterproof fiber sheets on the primer layer with an interval in the range of 5 to 10 mm and connecting the intervals with tapes to form a fiber sheet layer; applying thixotropic urethane having viscosity in the range of 900,000 to 1,000,000 CP onto the fiber sheet layer; and spraying hardening resin selected from polyurea resin or urethane RIM onto the thixotropic urethane to form a coating layer, wherein each of the waterproof fiber sheets is made of a knit fabric and has a plurality of holes with a diameter of about 5 millimeters formed in vertical and horizontal directions and having connection fibers passing therethrough, wherein the plurality of holes are separated from each other by woven portions of the waterproof fiber sheets, wherein the spaces between fibers of the woven portions are less than about 2 millimeters.
