ABSTRACT:
The present invention is directed to an expandable pre-formed plug that is suitable for sealing and/or structurally reinforcing a structure having surfaces defining a space therebetween. The plug is comprised of at least an expandable inner core having an outer surface and a transportable outer skin that preferably substantially encapsulates the core. In a preferred embodiment, the shape of the unexpanded plug is designed to mate with the surfaces that define a space therebetween upon expansion. The adhesive skin is generally dry to the touch at room temperature, however, upon initiation of expansion, the inner core expands and the surrounding skin is displaced in a coordinated manner. After some period of expansion, the outer skin preferably durably adheres or bonds to the walls of the surfaces defining a space therebetween and the outer surface of the core. A method for using such a plug is also disclosed.
