In this study, a test specimen was prepared to analyze the waterproof performance of concrete with waterproofing agents. The necessary construction procedure was determined in first, and the change of the relative humidity by the time variable according to strength, hydraulic pressure and cover thickness was investigated. Experiments were conducted to obtain basic data on materials and construction methods of waterproofing agents. For the analysis of waterproof properties, the change of relative humidity of each test specimen was relatively compared. The conclusions of this study are as follows; In the case of concrete mixed with a waterproofing agent, good waterproof performance can be secured by increasing the compressive strength and cover thickness. Additionally, in case of concrete designed with relatively high strength, if the water pressure is not high, it is concluded that moisture penetration does not exceed a certain range for concrete with a certain cover thickness. At any case, it is necessary to make and use accurate construction guidelines for using waterproofing agent.
