A double wall comprises prefabricated concrete slabs with in-situ concrete. In this process two parallel concrete panels, at least 5 cm thick, are kept apart by lattice girders. The concrete shells already contain the statical made to measure mesh. Double walls are pre-produced in the factory, delivered to the construction site, assembled and finally refined with cast-in-situ concrete into a solid wall. This produces a cured monolithic overall cross-section. The advantage of the double wall is the elimination of formwork on site; this significantly reduces construction time and keeps both surfaces smooth.
Field of application:
Double walls are used for residential, administrative, commercial and industrial construction and for industrial projects and have advantages when used in seismically active zones.
