<p>The invention relates to a water-stop composed of elastic deformable rubbery material for use in concrete structures. The water-stop has a substantially flat middle portion and enlarged side wing anchor portions provided with metal or elastic seals. A pad of elastically-deformable sponge material is attached to one surface of at least each of the side seals and attached to each pad so as to be sealed. At least one injection tube, of sufficient length to reach the outside surface of the concrete in which the water-stop is to be installed, is also provided. Each side seal is preferably attached substantially normal to each pad and a strip of elastically-deform-able sponge material secured to the flat middle portion.</p> |
