The secondary reinforced construction joint formwork element with its double-sided formwork element serves for the formation of an upstand for the wall/slab.
For joints in accordance with the WHG (Federal Water Act), the formwork element comprises a metal waterstop made of black steel or rustproof steel.
The metal waterstop is angled at the edge.
Installation takes place on the upper reinforcement layer of the slab, between the starter bars of the wall.
