Controlled Crack Joint

The secondary reinforced controlled crack joint for floor/ceiling slabs 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 reinforcement overlap between the first and second concreting section is ensured by the installation of the formwork element between the upper and lower reinforcement layer.
Concreting is not interrupted by the crack introducer.
