ABSTRACT

Building Owners have varying needs with respect to exterior masonry wall repair and the extent to which degradation and performance problems are corrected. The best ‘technical’ or typical ‘engineering’ solution to repair distressed masonry is not always appropriate. Factors such as repair duration, cost, aesthetics, impact on building operation, asset planning and leasing should be considered to develop solutions that meet the business needs.

To meet these needs, careful evaluation and innovation are required from the Design Professional. Options need to be carefully evaluated to find a repair that best meets the Owner’s objectives without compromising function or safety.

This paper examines the wide range of masonry repair options that have been applied to meet varying Owner requirements. The options include unconventional patch repair and coating, as well as more conventional targeted repair and replacement programs. Case studies are used to present the repair philosophy, demonstrate how the solution best met Owner needs, and the considerations, risks and drawbacks that needed to be addressed.
