Committee Mission: Develop and report information on the analysis and design of repair, rehabilitation, and strengthening of existing concrete and masonry structures.

Goals: 1) Address controversial or "gap" issues concerning concrete repair and rehabilitation not covered by existing documents through TechNotes; 2) Develop and report information on the analysis and design of repair, rehabilitation, and strengthening of existing concrete and masonry strucures; 3) Collect and disseminate information on sustainability and other topics of interest to the concrete repair and rehabilitation industry.
