Abstract

Desalination can be a solution to conserve our monuments, but on what conditions? With two desalination projects in Amsterdam in the last 2 decades, we’ve worked alongside the researchers of TNO and TU Delft to find solutions to create the optimal conditions for large scale desalination in situ.In project ‘De Waag’, the mail goal was to conserve the Masterpieces of masonry from the 17th century, which were damaged by mostly NaCl2. For an in-situ treatment we have looked at methods suitable to use at large scale. This resulted in a mechanical application of the poultice by spraying. While the treatment to reduce the saturation of salt was successful, a post -treatment was needed in order to clean the masterpieces of the debris left by the clay (kaolin) in the poultice. With knowledge of the Waag, the tower of the Zuiderkerk (1614), offered a new challenge. In this case sodium sulphate was the dominant salt responsible for degradation of the masonry. Reducing sodium sulphate has more risks, and those risks can only be controlled while applying a poultice in warmer condition. The main goal was to find a solution to partly heathen the wall on those parts of the tower where salt load was too high. Trying several electrical heating systems, we’ve found the most ideal option. Both projects resulted in some practical and effective options, but also lessons learned by all the trails conducted. Main conclusion is that large scale in-situ desalination is possible, and methods to make it effective can be useful for other projects, but only after extensive research and monitoring.
