The secondary reinforcedcontrolled crack joint formwork element 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 coated metal water stop for watertight joints. The special coating guarantees improved bonding between the concrete and the metal water stop.
Installation takes place in the joint area of the element walls between the lateral concrete shells.
