A waterstop for a joint between adjacent concrete blocks including first and second elongate sheet-like members (10) each comprising a substrate with an adhesive layer (12) on one side, the sheet-like members being continuously joined to one another along a longitudinal line (11) and arranged such that they overlap one another, and the adhesive layers being on the sides of the substrate remote from each other, such that the sheet-like members can be adhered to the respective faces of the concrete blocks at the joint to provide a seal therebetween. <IMAGE> |
