Abstract
The invention relates to a waterstop for providing a water-tight seal between layers of concrete. Flexible waterstops are known and are usually attached to a convenient structure such as steel reinforcing bars by individual loops of wire which pass through eyelets in the edge of the waterstop. The present invention provides a waterstop which has integral transverse loops of wire or similar strong material embedded in the waterstop material but projecting outwardly from it so that they can be used directly to attach waterstop to structure such as reinforcing rods or scaffolding. To provide strength, longitudinal stiffening members in the form of strands of cotton, wire or synthetic plastics material are knitted or woven into the inner portions of the loops embedded in the plastic or rubber waterstop material. These strands stiffen the waterstop and also help firmly to anchor the loops.
