arcform formwork in polystyrene foam are used to create concrete arches directly on the work site. The formwork is ready to use and permits reducing the costs of preparation and setting up.
The density of the polystyrene is chosen according to the arch dimensions, and in such a way as to withstand the pressure of the concrete; it can be coated with plastic film and thus reused several times thereby permitting a reduction in purchase costs.

The formwork is cut to the shape and size requested by the customer.
