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.

Fully bonded waterbar

A method for adhesively bonding two substrates by means of a moisture-curable adhesive composition, wherein at least one of the substrates includes at least 40 wt.-% of a mixture, said mixture consisting of: between 15 and 99 wt.-% of at least one thermoplastic polymer; between 1 and 85 wt.-% of at least one elastomer; and wherein the moisture-curable adhesive composition includes: at least one polymer containing silane groups; between 10 and 40 wt.-% of at least one polymeric plasticizer; between 0.1 and 5 wt.-% of at least one amino-functional alkoxysilane; between 0 and 5 wt.-% of at least one C1-C12-alkyl-functional alkoxysilane. The method yields adhesively bonded substrates without the requirements of using migrating plasticizers and pre-treating of the substrates.
