Hi there

Would someone please tell me how to cut into a 9" thick concrete garden
wall? I've tried using a large angle grinder but it won't go all the
way through and looking at stone cutters neither will they. I want to
cut a section out to put a gate in. Thanks to any replies.

Cut from each side using angle grinder.

Bash it out from the middle, tidy up the rough bits

OR

Hire a massive angle grinder
