Investigation about the decay of the timber structure of an ancient wine cellar in La Rioja (Spain) and sanitation proposal

In 2011 the collapse of one of the timber pillars that form the structure of the centuries-old warehouse of maceration that the firm "Bodegas Bilbaínas, S. A." helds in the town of Haro (La Rioja), occurred. This paper describes the most significant pathological processes existing in this nave, associated mainly to its wooden components. Then, according to the level of decay, the assessment of the damage in the different elements of the timber frame through nondestructive testing is analyzed, including the constructive and environmental conditions of the cellar. Finally, based on the results obtained, it is proposed the repair process and the design measures necessary to preserve the timber structure, taking into account the heritage significance and the extension of the harm of their components.
