ABSTRACT OF THE DISCLOSURE The invention provides a novel water-swellable caulking material which is a composite body of stratified structure composed of at least one rubbery layer swellable in water comprising highly water absorbing resin dispersed in the matrix of a rubber and at least one rubbery layer not swellable in water integrally bonded together, which latter serves to resist the expansion of the former layer when swollen in water in the directions other than the direction perpendicular to the plane of the layers. The inventive caulking material can exhibit unexpectedly excellent water sealing effect with easiness in handling in addition to the rapidity in water absorption by virtue of the structure thereof preventing the expansion of the material in the directions of length and width without decreas- ing the expansion in the direction of thickness.
