PROBLEM TO BE SOLVED: To provide a water-blocking material having fluidity at the time of pumping, small material separation at the time of casting in water, gelling after the casting, low water permeability and deformation followability. . SOLUTION: A gel is prepared by adding a clay mineral to a marine clay suspension having a water content of 100 to 300%, and adding at least one selected from silicates, alkali metal salts and alkaline earth metal salts. A deformation-following water barrier material that is modified into a state-of-the-art material. |
