Protective coatings are critical to concrete protection and remediation and they are characterised by the substance's makeup and ability to prevent ingress and deterioration of the concrete structure. Concrete deteriorates due to its reactions with elements such as chlorides, carbon dioxide, sulphates, acids, salts, and other chemicals/elements.

Coatings are widely used to provide extra protection and increase the durability of existing low-quality concrete structures and new structures which are not yet subject to deterioration, particularly structures exposed to severe and aggressive environments.

After suitable durability analysis and appropriate evaluation of possible coating remedial and protection systems can be conducted. NCS utilise coatings including (but not limited to);
