Crack appears stable but reduces continuity or permits ingress.
Use the site evidence to agree a project-specific method with the responsible engineer, concrete producer, manufacturer or specialist applicator.
Crack appears stable but reduces continuity or permits ingress.
Confirm inactivity and structural significance with monitoring and engineer assessment.
Shrinkage, one-time overload or earlier movement may have left a stable opening.
Where specified, use compatible epoxy injection or another engineered repair to restore bond.
Prepare and seal crack face; use approved port spacing, pressure and cure.
Record resin use, refusal and verification testing specified by engineer.
Epoxy injection is not an automatic answer to every visible crack.
