TAN 31 - Stone Masonry Materials and Skills

This Technical Advice Note describes the methodology used during the Glasgow project undertaken by the Scottish Stone Liaison Group. This project aimed to determine the repair needs of the stonework in Glasgow, the quantity and the type of stone required and the skills that will be necessary to carry out the repairs. The TAN is split into 2 main parts, the first giving guidance on mechanisms and types of decay and the second gives a detailed description of the approaches and methods adopted when carrying out the survey and recording the results.
