Abstract: This paper summarises a scientific methodology for assessing masonry decay, developed over the course of a four-year research project on Reigate Stone at the Tower of London and Hampton Court Palace. Reigate Stone is a vulnerable building stone with a complex history of use, high cultural value and poorly understood decay processes. The Tower of London and Hampton Court Palace, managed by Historic Royal Palaces, contain a large amount of Reigate Stone masonry. As such, these important historic sites provided a range of different case studies for investigating Reigate Stone decay. Masonry decay is increasingly being understood in terms of complex system dynamics, in which the interactions between primary building stone, replacement stones, mortar and invasive agents of anthropogenic or environmental origin are as important as the nature of the building stones themselves in controlling non-linear response to environmental mechanisms. Integrating this diverse set of variables significantly increases the complexity of scientifically robust stone conservation. Non-destructive techniques (NDT) play an important role in addressing this complexity, but in order to make sense of the data they capture, it is vital to appreciate different scales of investigation and distinguish between rapid and in-depth protocols.
