The ladder anchors on my pool deck definitely need to be replaced this year.
I'm going Bronze due to salt, and I know that there is special anchoring concrete to replace what I cut out, but I am unsure about the cut out process itself.
1. Should I cut out a square around the old anchor, or use a core drill to make a circle?
2. How much space should I cut out around the old anchor?
3. Am I right in thinking I need to find some metal after I cut out the old anchor to rebond the new anchor?
Thanks in advance,
