About this course

Gain a practical understanding and experience of repair and conservation methods for historic brick and flint work. Through demonstrations, lectures, and practical exercises you will learn condition assessment, appropriate repair materials and techniques, and how to apply these to historic brick and flint structures.

This course provides an understanding of, and basic skills in, the conservation and repair of traditional brick and flint masonry. You will start by learning about the nature and characteristics of materials, through study of a range of brick and flint buildings, which illustrate methods of construction, common failures, and decay processes. Common problems, including poor working practices, will be identified and solutions investigated. Methods of repair, joint treatments, and brickwork cleaning, gauged brick and flint work will be discussed and you will be able to practise repair and treatments in practical sessions.

By the end of the course, you will have a firm appreciation of the importance and characteristics of brick and flint as masonry materials. You will know how to assess the condition of walls, prepare the repair schedule and specification, and carry out the correct remedial work to a high standard. A tour of the brick and flint buildings on the college campus is included.
