Abstract
A ground impregnation process which is disclosed herein comprises injecting an alkaline ground impregnating material, with carbon dioxide gas passed through blowing nozzles joining said impregnating material, into a ground. In this process, the pressure of carbon dioxide and the opening size of the blowing nozzle are determined to provide a constant amount of carbon dioxide gas blown, irrespective of a variation in ground pressure. In this manner, the carbon dioxide gas joins the alkaline ground impregnating material at a given ratio.
