Abstract This study is for quality standard establishment of urethane waterproofing membrane method which is mostly applied to waterproofing method for underground parking lot and rooftop. The experiments were carried out on color differences, membrane thickness, tensile property by curing period of liquid urethane before placing protective concrete, and resistance of crack movement according to different substrate surface and reinforcement of non-woven fabric. As a result of experiments, it was found that color differences is increase, membrane thickness is thick, tensile property is low as concrete placing period is shorter. In the fatigue property, membrane thickness of 3 mm was not broken, but 1~2 mm was broken and in the case of the membrane reinforced with non-woven fabric was more stable comparatively non-reinforcement one.
