The "Fradiflex crack-inducer" from FRANK creates and controls the required shrinkage cracks for in-situ concrete and element walls, whilst at the same time providing a reliable seal. The simple and quick assembly of the crack-inducer guarantees a rapid construction process.
The larger size of wall sections for the construction of watertight in-situ concrete structures, means that so called crack-inducer elements are required to be integrated into the sections to avoid uncontrolled cracks appearing. These crack-inducers reduce the tension that occurs in the concrete which develops as a result of shrinkage. The result is a secure and watertight concrete structure with a high resistance to water guaranteed.
The Fradiflex crack-inducer by FRANK creates and controls shrinkage cracks in in-situ concrete and element walls. Due to Fradiflex’s inherent stability, it is possible to integrate the element quickly and easily. At the base the crack inducer is connected by overlapping to the base sealing Fradiflex metal waterstop and secured using two terminal clamps. At the top of the walls the crack inducer is also secured using fixing clips. Intermediate clamping is not required, which means that drilling or other assembly work is also unnecessary. This guarantees a quick construction process without hindering reinforcement installation or formwork assembly.
