How would you replace?
This fence is falling apart, but the posts are set into a giant trough of concrete. No clue how deep, but I have no interest in renting a jackhammer and then lifting all this concrete out into a trailer by hand, then unloading at the dump.
My current plan is to cut the posts at the bottom. Then use those metal brackets to bolt the post to the concrete a few inches over.
The problem is the concrete isnt level. What would you use to shim under rhe metal bracket? I'm afraid wood will rot.
What's the best approach?
