Double wall

A double wall (also called component wall) is made of two concrete slabs with a thickness of 5–7 cm each that are held together with truss-type reinforcement. In these concrete panels, the structural reinforcement for the entire concrete wall is built into the precast concrete component.

After the installation of the double walls, the remaining void is filled with mix-in-situ concrete; therefore, this double wall is a semi-precast part. This produces a monolithic, dense and extremely solid concrete wall. The double walls thus combine the major advantages of prefabrication with the advantages of a wall that has been produced on site with concrete poured into casing. Double walls are used for the walls in basements and each storey.

Often, double walls are produced with core insulation (with insulation inside them) so as to be able to guarantee compliance with regulations concerning thermal insulation. For structural calculations, a double wall is treated on the basis of its full thickness in exactly the same way as a wall that has been produced by concrete poured into casing.

New Caledonia, the dream island, relies on precast concrete construction

New Caledonia, the French archipelago in the South Pacific, 2,000 km away from the Australian coast is among the world's most popular vacation destinations with temperatures between 20 and 30°C and gorgeous beaches and diving resorts. In pursuing the construction of new buildings for residential areas, public administration and touristic projects , state-of-the art precast production techniques are used. Architecturally attractive single-family homes, multi-storey residential buildings will be produced as well as hospitals, schools, entire hotel complexes and industrial halls. The precast plant of the LBDP Group in New Caledonia completed in April 2014 will produce floor slabs and double/sandwich walls as well as columns and beams in future.
