PURPOSE:To solidificate a soil surface and waterproof it by mixing together dialdehyde starch and water soluble high molecular compound having hydroxyl group or amino group, amide group, amide group methylorede, and spraying the mixture onto the soil surface. CONSTITUTION:Dialdehyde starch and water soluble high molecular compound having hydroxyl group the aqueous solution viscosity of which is 5-1,000cp, or amino group, amide group, amide group methylorede are mixed together. And this mixture is sprayed onto a soil surface to be impregnated therewith so as to form water insoluble high molecular gel body. Thereby the soil surface can be processed according to the method whereby its water resistance is made higher, its intensity stably maintained in a longer period, and its appearance less damaged than by conventional methods. |
