Located in the north of Spain, the wine cellars are laid out to a U-shaped plan. The basement area between the two hall tracts houses the new bodega, the roof of which is in the form of a series of reinforced concrete cross-vaults. This construction serves not only to bear the great loads; it also ensures constant, low temperatures. The vaulting is articulated into nine 18 x 18 m bays with a clear height of 6 m at the crests. A system of tensile strip foundations was designed to link the haunched seatings of the vaulting and to bear the compression loads. The foundations were executed without joints, whereas the bays of the roof structure are separated by expansion joints at the edges of the modules. These joints absorb distortion within the vaulting and prevent cracking.
