How to Fill a Deep Drilled Hole in Concrete?
Asked by User123!@#
I accidentally drilled a hole that's around 5cm deep and now I need to fill it back up. I'm not quite sure how to properly inject a cement mix into the hole so that it looks good. Additionally, one of my drop-in anchors broke and left some parts inside the hole. What's the best way to handle that?

First, make sure to clean out the hole really well. Use a vacuum or compressed air and maybe a large pipe brush to get all the debris out. Once it's clean, go for some hydraulic cement. Mix it up and pour it into the hole. Just remember to smooth the top quickly since it hardens fast!

RepairGal77: Totally agree! A tip is to use some of the dust you cleaned out and press that into the hydraulic cement once it's in. It’ll help blend it in nicely with the surrounding concrete.
