Abstract: 
From our analysis of numerous concrete repair/rehabilitation specifications, and based on practical experience of their application, it can be concluded that these specifications are rather limited and do not present adequate durability provisions. Current specifications for concrete repair are typically lacking restrictions to critical factors affecting repair durability such as compatibility, permeability, resistance to cracking, shrinkage, etc. This shows a need for improved guidance in addressing issues related to improved performance of repaired concrete structures. Though it is a common situation, it is often disregarded that many of the problems that our repaired structures prematurely experience could have been prevented during the design process and, of course, with comprehensive and properly engineered technical specifications. In this paper the engineers performing the task of “designing” repair specifications are challenged to leave their “sleeping beauty” positions and critically think about obtaining high quality repairs, tailored to the specific structure and the environment they must perform in. With special attention to repair durability, this paper offers some critical thoughts on currently specified requirements and test methods.
