Over about 30% of problems in construction is related to water-leaking, and the loss from this problem can incur as much as three times the cost of initial construction. Thus, water vapor pressure is known to be the primary cause of defective waterproofing. Accordingly, the theories on the relationship between water pressure and temperature as well as damp-proofing volume of concrete and the change in vapor pressure volume were reviewed and analyzed in this study by making test samples after spraying a dampness remover and applying waterproofing materials to the prepared test specimens. The result of measuring water vapor pressure with the surface temperature of the waterproofing (fluid-applied membrane) layer at the experimental temperature setting of about 10℃, which is the annual average temperature of Seoul, indicated that (1) the temperature of the fluid-applied membrane elevated to about 40℃, and the water vapor pressure generated from the fluid-applied membrane was about 0.03 N/㎟ when the surface temperature of the waterproofing layer was raised to about 80℃. (2) when the temperature of the fluid-applied membrane of the waterproofing layer was raised from 30℃ to 35℃, water vapor pressure of about 0.01 N/mm2was generated, and (3) when a thermal source was applied to the fluid-applied membrane (waterproofing) layer, the temperature increased from 35℃ to 40℃, and approximately 0.005 N/㎟ of water vapor pressure was generated.
