Controlled Crack Joint with Metal Waterstop

The application of in-situ concrete control joints serves the controlled reduction of shrinkage stress and prevents uncontrolled crack formation in in-situ concrete wall panels.
The controlled crack joint elements are equipped with crack-inducing metal elements, which lead to a defined crack at the predetermined breaking point. The integrated coated metal waterstop is coated with bitumen-free polymer and leads to improved bonding with the fresh concrete.
