11 Abstract Double-walled formwork element and process for manufacturing it Proposed is a double-walled formwork element comprising two large-area panels suitable for use as mould shuttering, particularly in the concrete construction industry. The two panels are joined to each other by force-locking, liquid- tight and gas-tight engagement, and form between them a cavity. The invention secures the two layers of shuttering against slippage and ensures the discharge of any leak liquid produced. The invention also enables shuttering systems to be assembled cheaply and simply for constructions of various shapes.
