About this course

Riched20 10.0.16299
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 and includes constituent materials and 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, practical demonstrations and practical exercises will be complemented by films and discussions.

Scope of Training
The course includes the development and implementation of a philosophy; manufacture and construction processes; constituent materials and their characteristics; weathering and decay processes related to detailed design and environment; corrosion of reinforcement.

Surveying, recording and assessment of condition; suitability of proprietary repair systems; applying traditional repair approaches; assessing cracks, corroding reinforcement and surface spoiling; patch repairs; casting techniques; matching surface finishes; cleaning and other surface treatments; maintenance programmes; the importance of patina.

It will also include films and discussions about Park Hill Flats, Sheffield and the extraordinary concrete creation in Mexico, Las Pozas, created by the former owner of West Dean, Edward James, which is a current conservation challenge.
