Holistic system approach to design and implementation of concrete repair

Concrete repair is a complex process, presenting unique challenges that differ from those associated with new concrete construction. The repair process must successfully integrate new materials with old materials, forming a composite system capable of enduring exposure to service loads, exterior and interior (inside the structure) environments and time. The durability of this composite system must be ensured on a systematic basis of daily practice – from the research, condition evaluation, realistic design objectives, detailed design and material selection, through construction practices and quality control. The paper discusses the key characteristics of a holistic system approach to concrete repair projects.
