った。(Prior art) Conventional waterproofing methods for buildings include the coating film waterproofing method, in which a liquid composition is applied to the surface of the building base and a coating film is formed by drying or curing, and the method in which sheets molded in a factory are bonded together. So-called adhesion methods have been used, such as the sheet waterproofing method in which the asphalt is pasted to the surface of the base with an adhesive, and the asphalt waterproofing method in which the asphalt is directly heated to give it fluidity. However, such a close-contact construction method has problems such as swelling and peeling of the waterproof layer due to water remaining in the concrete slab turning into water vapor.

穴を開ける必要があり好ましいものではない。As a method to solve these problems, an aeration waterproofing method has been proposed in which an aeration layer is provided between a waterproof layer and a base such as a concrete slab surface. As the ventilation layer in this method, a grooved sponge, open-hole sponge, or non-woven fabric is used, and as a method for releasing water vapor from the ventilation layer to the atmosphere, - A device called a degassing tower is used for boat fishing. There is. These devices are installed mainly in flat areas with the devices protruding from the upper surface of the waterproof layer. The durability and weather resistance of the fruiting device are problematic, and it is also not aesthetically pleasing. Furthermore, in specifications for use on rooftops such as light walking finishing, this device not only becomes a nuisance but may also be dangerous. Furthermore, when installing a degassing tower, it is necessary to make some kind of hole in the waterproof layer, which is not preferable.

るという欠点があった。Furthermore, as a method to improve these drawbacks, Japanese Patent Application Laid-Open No. 61-2
Japanese Patent No. 74039 discloses a method of forming a ventilation layer by creating a space between a tape-like material and a base slab so that they do not come into close contact with each other. With this method, it is difficult to release water vapor from the base;
Another drawback is that the ventilation passages are blocked when pressure is applied to the top of the waterproof sheet.

The construction cost is high because a breathable waterproof sheet is used up to the rising part. Furthermore, since all edges of the waterproof sheet are in contact with the atmosphere, there is a high risk of water leakage.
