If the expansion joint is to be additionally sealed, a rubber water bar cage is integrated into the Stremaform® stay-in-place formwork for expansion joints during production. The expansion rubber water bar is inserted into the cage at the building site. The built-in expansion joint fixer ensures the correct position of the rubber water bar.
For wide rubber water bars, we recommend a formwork element design in which the rubber water bar is rolled out on the lower part before the upper part is positioned and secured.
