How to: Simple manufacture of expansion joints with complex component cross sections

Whether for force transmission, sealing or special component geometries – there is a great deal of variation in the execution of expansion joints. For that reason, the manufacture of this formwork on the building site is often complex, unreliable and time-consuming.
Stremaform^® formwork elements for expansion joints are prefabricated according to the project requirements and delivered as a precise fit.

• Stremaform^® formwork elements for expansion joints are planned and manufactured in Germany in accordance with the formwork and reinforcement diagrams.
• All details such as expansion joint insert and rubber water bar cage are already integrated in the factory.
• On the building site the expansion joint elements only need to be positioned and fixed between the existing reinforcement of the concreting sections.
• The expansion joint rubber water bar is inserted into the rubber water bar cage.
• Shear force dowels are inserted into the factory-made recesses if necessary.
• The first and second concreting sections can be concreted simultaneously or successively.
