Abstract

A pontoon provides buoyancy for a protection barrier to be provided in a body of water. The pontoon includes a metal structural member; a urethane inner shell that encases a portion of the metal structural member; a polyethylene region that encases the urethane inner shell; and a polyurethane elastomer or polyurea outer shell that encases the polyethylene region. A portion of the metal structural member extends out from the outer shell to thereby couple to a portion of the protection barrier.
