PURPOSE: A method for waterproofing a membrane with liquid capable of enabling a worker to observe defects with the naked eye through a transparent amorphous polymer resin is provided to easily perform the maintenance work of a waterproof structure. CONSTITUTION: A method for waterproofing a membrane with liquid capable of enabling a worker to observe defects with the naked eye through a transparent amorphous polymer resin is as follows. A membrane waterproofing structure comprises a concrete bottom, a transparent waterproof layer, and a moisture detection unit. The transparent waterproof layer is spread on the top of the concrete bottom. The moisture detection unit is formed between the concrete bottom and the transparent waterproof layer and senses that moisture flows into the concrete bottom.
