。DETAILED DESCRIPTION OF THE INVENTION The present invention provides an asphalt waterproofing layer that uses room temperature curing synthetic resin to prevent blistering of the waterproofing layer caused by pinholes that occur in the underlying concrete layer during asphalt waterproofing of concrete structures. Regarding anti-blister treatment methods.

正は不可能である。Conventional asphalt waterproofing methods use an asphalt adhesion method in which a surface treatment agent such as an asphalt primer is applied to a concrete base and an asphalt layer is formed after that, or an asphalt sheet is melted and adhered to form a waterproof layer. However, in this close-contact construction method, the surface of the concrete structure to which the base treatment agent is applied is uneven, so uneven coating tends to occur, and air tends to remain at the bottom of the concave portions. Before a uniform base layer is formed by drying, pinholes are likely to occur due to the moisture in the base concrete and the expansion pressure of the air. Because the coating layer is thin, swelling from the base is 1! Correction is not possible as it cannot withstand pressure.

ふくれ現象を起し、遂には防水層にピンホールを発生し
て防水層の剥離等が起り漏水原因′となる。Conventionally, this asphalt waterproofing adhesion construction method did not have an appropriate method for treating the pinholes that occurred, so the waterproofing layer was formed with the pinholes left in place. Therefore, in the summer, due to the rise in temperature, the waterproof layer swells at the base pinhole area, and pinholes eventually occur in the waterproof layer, causing peeling of the waterproof layer and causing water leakage.

よっては垂直に削ってもよいことは勿論である。The treatment method of the present invention is used to prevent blistering of the waterproof layer caused by pinholes in the asphalt adhesion waterproofing method for concrete structures. In such cases, the entire shallow surface is scraped flat, and a low-viscosity, fast-curing cold-curing epoxy resin or cold-curing asphalt epoxy resin is poured into the scraped area, and a thick coating is applied to reduce the expansion pressure of the pinholes and areas. was able to be completely suppressed. Next, by applying molten asphalt or melting and pasting an asphalt sheet on top of this to form a waterproof layer, it is possible to prevent blistering of the waterproof layer due to pinholes, and even in the case of foamed concrete, uneven areas on the base surface can be completely removed. The waterproof layer that was previously lost is now available. In the present invention, the base layer to be scraped has an inverted conical shape, but it goes without saying that it may be scraped vertically depending on the case.
