The document discusses concrete repair strategies and methods. It explains that proper maintenance of concrete is important to ensure longevity, as there are many causes of concrete damage. Concrete repair requires skilled professionals to properly diagnose issues, select repair products and techniques, and implement solutions. The document outlines 11 principles of concrete repair from the EN1504 standard, including protection against ingress, moisture control, and concrete restoration. It provides examples of repair methods like injection, overlays, and strengthening. Finally, it recommends Sika concrete repair products that align with the different principles and application techniques.
