Square top to round concrete pier? How to?


Hi folks,
I am putting in a patio cover that will rest on 8" diameter round concrete, poured into forms from home depot. The previous rotted patio cover also had piers, but they were square on top where the posts go. It looks nicer. I couldn't find any cardboard forms that do this, whats the best way to do it?

Thanks in advance!

If you want square, you will have to form the pier using wood or build it out of masonry. The round forms you are talking about are probable "Sonotubes", that have been used for many years and are available in sizes up to about 24" diameter.

Use your own forms out of wood. What's the problem?

Yes they are the Sonotubes. The problem is that I am no good at concrete forming and got them because they are straigtforward. What's an easy way to make the tops better looking (I guess I am not hooked on square)? Will be attaching 6x6 posts with the brackets that lift the post 1" off the pier.

Use Simpson strong ties they have a bracket that you place in the cement that is square and then you place the post in it make sure you use the Z rated strong tie if you use pressure treated wood. Just so you under stand you pour the cement in to the sono tube and then work the cement with your hand trawl and then set the bracket in. let is set up for a week and then place your post secure it with the right Simpson bolts and voila you have something that will last for ever!

Have pieces of limestone cut and mount them on top of the sona tubes.

That won't fly if he is a D1 or D2 seismic zone. If he lives on the west coast he has only one way of doing it just how I explained it.

Thanks, I like both ideas. I am already using the Simpson strongtie, though, and it's just a square bracket for the end of the post. It doesn't cover up the end of the sonotube at all.
