About this course

Learn how to analyse historic mortars and how to recognise defects commonly found on historic structures. This course will enable you to carry out condition assessment and development and evaluation of appropriate remedial work options. You will learn how to prepare and apply lime-based mortars using a range of methods, materials, and tools.

You will be given access to online content from Mon 9 September prior to attending practical workshop and classroom sessions at the College on 14-16 October 2024. There will be 3 online meetings, on Tuesdays from 6 to 7pm on: 24 Sept, 1 Oct and 8 Oct. These meetings will be recorded and made accessible for those unable to attend on these dates. Online content includes a practical exercise in assessment and condition survey of historic mortar on a building of your choice and a short informal presentation (approx. 10 minutes) to the group.

This course is open to anyone with an interest in historic buildings and their conservation, it is designed for those with some knowledge of building conservation who wish to develop their practical skills and experience. BCM students typically include a mix of building professionals and practitioners. Participants normally find that interaction with others on the course is a key part of their learning experience. If you have no knowledge in the field of building conservation you may find you need to do additional reading or other work to benefit fully from the course. This course is one of the seven core Building Conservation Masterclasses required for completion of the PDD (Professional Development Diploma) in Historic Building Conservation and Repair. Access to online elements to be released by Mon 9 September and will expire on 28 November.
