Flaking concrete surface? Answered
Thanks for this class! I am a potter but have often thought I would like to try concrete for larger projects.
I have a question about a retaining wall and steps I had built last year. The surface of the steps flaked off badly after a long snowy winter, exposing the aggregate. Now a corner of the retaining wall has chipped off. Besides the cosmetic issues, I am concerned about the interior strength of the retaining wall. It does have rebar in it.
Also can the surface of the steps be repaired or would a "patch" just flake off?
I have been told that the concrete wasn't sealed and that the surface wasn't worked enough so that the aggregate wasn't pushed down far enough.
