PURPOSE:A ground impregnating agent for stopping water that is made by adding a sodium salt caly, a cationic inorganic flocculant and water in a specific proportion to form safely and steadily a ground of low water premeation coefficient by impregnating a ground from which water is springing and flowing. CONSTITUTION:The objective impregnating agent is produced by adding (A) 40-100g/l of sodium salt clay, (B) 5-20g/l of a cationic inorganic flocculant, preferably aluminum sulfate and the residual of water. As a component B, polysodium chloride, sodium aluminate, ferrous or ferric sulfate is usable. |
