PROBLEM TO BE SOLVED: To provide water stop material for simple construction, which effectively prevents reoccurrence of water leakage and eliminates the possibility of pollution. SOLUTION: Water stop material is formed by mixing ordinary cement with seaweed ginkgo nuts and rinse in a proper ratio, e.g. By changing the mixture ratio of the ginkgo nuts to the rinse, a hardening time can be controlled. The water stop material filled directly into a crack without removing water therefrom begins to be adhered to the crack as it is and then it is hardened and fixed thereto after six to seven hours. |
