摘要

The present invention is to provide a water cut-off agent capable of being applied in a simple manner and having excellent cut-off capabilities. The permeable water cut-off agent of the present invention comprises, as the essential components, a hydrophilic resin and a gellant for the resin. It may be wrapped with a water-pervious material, or may be mixed with water for spread, or may be impregnated into films or spongy substances.
