I have a couple sites where wall attachments need upgrades. In some cases the threaded rods would need to be replaced with larger diameter rods and/or deeper embedment.
Is it possible to reuse the holes in order to limit the number of building penetrations? I’m just thinking this would be difficult to remove the bonded anchor, re-drill the hole by the next size up, and then reapply the adhesive. Is reuse a possibility?
If reuse isn’t a possibility and then anchorage point is lowered on the wall (say by a minimum of 3xhef), is there any point to removing the previous anchor and sealing the hole (grout) other than aesthetics and corrosion?
