Architecture and the construction industry are increasingly demanding precast concrete elements that are not only functional but also sophisticated in terms of design. Complex free-form shapes, seamless façade elements or individually designed street furniture have long been part of the requirements profile of modern construction projects. However, the production of these components is still associated with high costs and restrictions. Traditional formwork made of wood, GRP or polystyrene is not very suitable for geometric free-form shapes, undercuts are almost impossible to realise and demoulding bevels considerably restrict design freedom. This is precisely where the Flex-Core research project comes in. Together with the Steinbeis Innovation Centre and Wasa Compound GmbH & Co KG, a new type of flexible formwork technology has been developed that can open up completely new possibilities for the precast industry.
