Study and evaluation of the wooden foundation system of Venice

Large part of Venetian historical building foundations evidences a founding system based on wooden piles, which were plunged into soil in order to increase its mechanical characteristics. In this way, a composite system constituted by wood, water and clay is realized. Such composite system constitutes the basis of foundation stones, and it can evidence diversified mechanical characteristics depending on the decay processes affecting wood. It is commonly believed that this complex system is characterised by a very good stability from the chemical-physical and microbiological points of view. However, previous investigations evidenced that after centuries wood undergoes some decay processes because of the action of anaerobic bacteria. As for the activities specifically carried out by the Laboratory of Chemistry of Wood and Wood products, aim of the Project is the evaluation the residual mechanical characteristics of wood, by relating these characteristics to its present state of preservation and present chemical composition (in terms of cellulose and lignin). Activities are carried out in cooperation with the Laboratory of Wood Anatomy, which coordinates the project for Ivalsa, and with the University Ca’ Foscari (Venice), the University of Padua, the Soprintendenza per i Beni Architettonici e Paesaggistici di Venezia e Laguna and with CORILA.
