Controlled Crack Joint with Waterstop

The secondary reinforcedcontrolled crack joint for the wall area serves for targeted crack formation along the crack introducer.
Crack formation as a result of weakening of the concrete cross-sections takes place due to the integrated separation layer at 1/3 of the component thickness/cross-section thickness.
The formwork element comprises a rubber water stop for watertight joints.
The reinforcement overlap between the first and second concreting section is ensured by the installation of the formwork element between the lateral reinforcement layers.
Concreting is not interrupted by the crack introducer.
