The maintenance, restoration, preservation, and retrofit of existing masonry structures requires a comprehensive project team approach. The ultimate success and performance of the repairs, however, is dependent upon proper material selection and the quality of masons performing the work. Existing and historic masonry buildings represent a cross section of construction technology and are comprised of materials and methods that may no longer be readily available. Therefore, repairs to these structures require a systematic approach which begins by understanding the entire building envelope, both as it was originally intended to function and how it will function in the future. In addition, the individual materials that comprise the system need to be assessed to evaluate long-term performance. These preliminary steps will help inform the types of contemporary and traditional repair materials that will be most appropriate and compatible with the existing masonry.
Let us connect you with craftworkers who have the expertise to perform sensitive restoration work. Our Historic Masonry Preservation Certificate Program (HMPC) is an intensive 6-day, 50-hour course that teaches traditional craft skills and contemporary repair techniques to members of the International Union of Bricklayers and Allied Craftworkers (BAC).
The best way to make sure you have the right team for the job is to use our pre-qualification language for HMPC in your project specifications.
The APT Building Technology Heritage library contains hundreds of digitized architectural trade catalogs, house-plan books, and technical building guides on masonry from pre-1964, many contributed by IMI. These primary source materials are critical in documenting past design and construction practices and can aid in preservation and conservation efforts. The APT Building Technology Heritage library is fully searchable and filterable by topic for browsing ease.
