Abstract: A method for installing a sealing element for a concrete joint, which avoids the use of split formworks. The sealing element used in the method includes a body having a center portion and first and second side portions on opposite sides of the center portion. It is further directed to a sealed concrete construction obtainable by using the method.

Abstract: A sealing element for sealing joints in concrete structures including a profile having a center portion and first and second side portions on opposite sides of, the center portion. The side portions of the profile are at least partially covered with a functional coating which is operative to bond with a fresh cementitious composition casted against it and allowed to harden. A method produces a sealing element, a method seals a joint between two sections of concrete, a sealed construction, and a use of a sealing element for sealing of a joint in a concrete construction.
