Fence Post Base

RedDog100 | Posted in Construction Techniques on May 12, 2003 10:34am

Does anyone have a recommendation for post base hardware for a fence post? I have a concrete driveway, and would like to install a 6-foot fence on one side. I would prefer not to core through the concrete to sink a fence post. I would prefer to install a fence post base (if one exists) and then attach the post to the post base. I checked Simpson ties, but none are recommended for this application. Any comments or suggestions would be appreciated.

not much you can do that I can think of. I'm doing a fence for someone now. Auguring holes and placing the posts in concrete. Another thread floating around suggested pouring concrete with a 3 foot piece of galvanized steel sticking in the concrete 18" or so and fastening it to the post. Keeping the post out of the concrete. Great idea, but you'd still have to auger holes. Maybe someone here has got some suggestions.

6 foot fence, that will have pretty high wind load, so you will have to bore through the cement drive way and go down past the frostline, dont know of any other way

Cliff, I did a fence on a slab a couple years ago. Went to a local steel yard & found some heavy rod in the surplus department.

It was about 1&1/4"+ in 4' lengths. I drilled the slab and then pounded the rod in about 2'. I put some galvanized 16's into the gap to really tighten things up.

Drill your posts and set them on, and maybe a plastic spacer of some sort to keep it above the slab.

When it's all done it's pretty solid.

I bought a house once that had a foundation for a breeze way that never got built. I rented a drill and hole saw. Drilled maybe 2" diameter holes, put 1.5" galvanized pipe in and poured PourRock in the pipe and hole. I then built a 6'tall box of cedar 1x4, slid it onto the pipe and screwed through the cedar into the steel in several places. Don't fill the pipe too far or the screws won't go in.

How about drilling a hole (1" or so) and anchoring threaded rod into the hole with a hydraulic cement.(www.wrmeadows.com) stuff sets up in about an hour! then bolt on standard post hardware

From my experience, a 6 foot tall fence is too tall / heavy to be supported by base mounts. It might work for awhile - but might not hold up over time if pressure is applied to the fence or posts.

Will installing an 8' high posts with a "header" to the building meet your needs?
