Volume defining wall for molding e.g. concrete in public work field, has reinforcement including portion that is arranged in one of cores and extended along length of core, where reinforcement is made of steel and held in core by friction
The wall (1) has a hollow sheet (3) made of polymer i.e. polypropylene, where the wall is non-plane. Cores (4) are extended in parallel to opposed main faces (8, 9) of the sheet. An elongated metallic reinforcement (7) has a portion that is arranged in one of the cores and extended along a length of the core. The reinforcement is made of steel and is held in the core by friction. Transversal sections of the reinforcement and the core are complementary to each other.
