Workshop:
Skill level: Intermediate
Workshop facilitators will address the physical and chemical characteristics of cast stone, concrete, and precast concrete. With origins in antiquity, concrete building materials used in the 19th and 20th centuries, including concrete, precast concrete and cast stone, present a range of preservation issues. They will discuss new and historic construction techniques for each material, as well as techniques of field and laboratory investigation, and methods of repair, restoration, and protection for cast stone, precast and historic concrete.
You will learn techniques for repair of each of the materials, the types of repair materials, and the challenge of matching of existing materials. You will also participate in theoretical investigations led by experts, have the opportunity to examine samples in a laboratory set up especially for the course, to participate hands-on in examples of cast stone and concrete repair.
Format:
The workshop will be a combination of lectures, discussion, hands-on laboratory and contractor craftsman demonstrations and practical exercises.
