About this course

This course is intended for architects, surveyors, engineers, contractors and conservators working with architecturally or historically significant structural or decorative concrete.
It has been prepared in response to the increasing number of concrete buildings, both pre-cast and in-situ structures, which are now recognised as historically significant and are being listed.
The course discusses how to develop and implement a conservation and repair strategy for concrete buildings, including constituent materials, construction processes and consideration of weathering and decay processes. It will consider how to address both design deficiencies and changing performance requirements, and will cover testing methods.
Lectures, demonstrations and practical exercises will be complemented by films and discussions.
