About this course

Designed and Delivered in Partnership with English Heritage.

This course is primarily designed for those concerned with the conservation of ruined structures, although the principles and skills are also applicable to roofed buildings.

The course covers traditional masonry construction and the identification of mechanisms of decay and structural failure, selection and application of conservation and repair techniques, identification and replication of historic lime and earth-based mortars, the selection and application of mortars and grouts, and soft and hard wall capping. The course is delivered using a combination of lectures, demonstrations, group discussion and practical sessions working on the masonry Ruinette.

Course Description

The course is designed to deliver an understanding of the unique and often complex challenges that ruined structures and their sites typically present, where structures typically host flora and fauna and the needs of protected species and protected fabric must be balanced, as well as the needs of visitors. Learning outcomes include:

  • An understanding of the methods and materials used in construction of historic masonry and how ruined structures deteriorate.
  • The ability to recognise evidence of past interventions (structural, aesthetic) and how these impact on current condition and conservation (treatment) options.
  • The ability to diagnose characteristic defects of masonry ruins and design repair and conservation work to stabilise masonry and prevent loss of historic fabric.
  • The ability to consider and develop nature-positive solutions for ruined sites.
