とが可能である。An anti-termite sheet using the water-resistant sheet-forming composition,
It is sufficient to simply mix the termiticide with the water-resistant sheet-forming composition, and it is sprayed onto the construction surface, and as soon as film formation begins, the termiticide is incorporated into the matrix of the film, improving water resistance and resistance. It is protected by an alkaline film and exhibits a stable anti-termite effect over a long period of time. In addition, unlike the conventional anti-termite treatment after construction of Moisture-proof Funkuri-1, there is no need to drill holes in the concrete, and the construction operation is simple, so no skill is required, significantly reducing labor and time. It is possible.
