With aging of the infrastructure and many concrete structures reaching the end of their design life, maintenance and repair is becoming an increasingly important part of the design and construction industry. Complex decisions have to be made in the selection of repair materials and systems in infrastructure rehabilitation. Compatibility of the repair material with the existing substrate is an important consideration if the repair is to withstand all the stresses induced by influences such as volume changes, and chemical and electrochemical effects. This paper briefly reviews some of the major requirements for design and construction of durable repairs. The importance of installation of repair materials and systems with suitable dimensional compatibility, bond compatibility and durability (including proper surface preparation), structural and mechanical compatibility, and electrochemical and permeability compatibility is reviewed. Case history examples are presented where lessons can be learned from a failure to adequately take into account in design or construction one or more of the preceding compatibility requirements. (A)
