The fence company said they put their posts 3' under grade (the posts are 6' tall above grade). And use concrete around the posts.
Now from reading another thread on concrete and fence posts (albeit for wood ones). Is the best way to have them do a "quality" install, request they -
(a). pre mix the concrete OUTSIDE the hole (b). have them put some gravel in the hole first, then the concrete
This installation is in NJ southern ocean county. relatively sandy soil.
What about "frost heave" ? should there be some specific forms to make the concrete a certain shape? (say an upside down cone with larger end facing down).
No contracts signed yet and I want to make sure I spec out the best way for them to do do it.
Any suggestions/advice on "best practices" to have it done the right way ?
