#### 초록

Urethane and epoxy waterproofing membrane coating, which is most widely used at present, involves problems such as the long time of drying, environmental pollution due to a large quantity of volatile solvent generated in the drying process, etc. Accordingly, the objective of this study is to diversify the advantages of photocurable resin with no volatile solvent. To this end, its availability as an alternative to existing epoxy and urethane waterproofing membrane coating is examined, and an experiment was conducted to present a basis for construction manuals to secure proper quality. Experiment results are as follows: (1) To secure a level of bond strength that satisfies the quality standards in using photocurable resin for waterproofing membrane coating, the irradiation distance should be within 100mm and the irradiation angle within $90^{\circ}{\pm}22.5^{\circ}$, and the time at least 20 seconds in principle. (2) As for the adhesive strength of photocurable resin depending on the base surface materials, that for mortar should be $3.23KN/mm^2$ and that for steel sheets $6.14KN/mm^2$. The suggested material satisfies these quality standards. (3) When photocurable resin is used for mortar in various temperature conditions, the value was $1.95KN/mm^2$ in the condition of mortar at $20{\pm}2^{\circ}C$, and $1.74KN/mm^2$ at $30{\pm}2^{\circ}C$ respectively. (4) When photocurable resin is used for waterproofing membrane coating of mortar, a primer should be applied in order to secure adhesive strength high enough. Thus, the suggested material can be utilized as an alternative to waterproofing membrane coating, an existing volatile solvent.
