Cover concrete breaks away and steel is visible.
Use the site evidence to agree a project-specific method with the responsible engineer, concrete producer, manufacturer or specialist applicator.
Cover concrete breaks away and steel is visible.
Map delamination; measure cover and assess corrosion, carbonation or chlorides.
Corrosion expansion and poor cover can drive repeated spalling.
Have structural capacity reviewed; remove unsound material, address steel and rebuild with compatible repair mortar.
Prepare edges and steel, follow bonding and curing requirements, and restore protection.
Inspect substrate and steel before closure; verify repair soundness and cover.
Do not patch loose concrete or conceal substantial steel section loss.
