Concrete repair is a complex process with unique and unexpected challenges. The experiences with concrete repair problems are very much different than those which we encounter during construction process. The best integration of repair materials with the old concrete substratum to ensure strength, durability and bonding in changing environmental and exposure conditions pose serious challenges to a concrete technologist and repair specialist.

Concrete repair problems must have started with the first concrete placement. Today concrete repair is a major industry supporting every structure that is built.

The repair industry is a network of contractors, engineers, architects, material manufacturers and suppliers, where each play an important role.

Understanding the right philosophy of repair through root cause analysis, identification of the cause and effect, conducting repair analysis, formulating repair strategy as per user, structural and environmental needs, designing the repair methods, establishing material properties, selecting the repair materials and executing the repair and restoration work is an engineering and art.

Many repair works are carried out by non-professionals without understanding the above mentioned “repair and restoration philosophy”, leading to earlier failure of the repair work. The impact of poor repair work on service life of the structure is enormous. Many customers fail to understand the hidden “quality” costs behind a poorly executed repair work and decides to go with “cheap repairs” which results in physical and economic losses in near future.

A systematic and clear approach to problems and solution to concrete repairs is the need of the industry.

CETARC will support our customers to understand the “right philosophy” of repair and restoration work whereby extending the service life of the structure.
