We would like to install a 6' privacy fence with 6x6 cedar posts, between our house and driveway, that would involve 3 posts on top of our cement driveway and 1 in the ground. My intention was to hire someone with a core drill to dig 3' holes for footings, and pour cement into 10" tubes, but I am now wondering if it is "ok" to just install the footings directly on top of the driveway.
I have not checked the depth of the cement yet, so is there a recommended driveway depth for this sort of thing, if I can install directly into the existing cement? Or should I go ahead and get 12" holes taken out with a core drill and create 3" deep footings?
Also, is this a proper post anchor to use? It is the only type they had at our store.
