We’re getting a new concrete patio poured in a few weeks. At some point, we may add a roof/trellis to the patio. Because of that, we’re having them pour footers for each of the posts as well.
The catch is that we’re not sure if/when we’re going to get to this second phase. So, are there any viable options for creating anchors for these posts that aren’t too obstrusive until then? I’m thinking standard bolts would work, provided I build a planter stand or something around each one. But looking for any other thoughts…maybe a embedded pipe that’s flush with the slab that we could cover and later use as a ‘sleave’ for an achor rod/pipe?

IMO, Better to dril in wedge bolts when you are ready

What Piffin said, but I favor epoxied all-thread rod for ultimate strength. Make a paper map of where your thick sections are, and file with your other house documents, so you will "remember" how to find the locations in ten years when you get around to it.

Drilling it is! How deep to these bolts have to go? Is it relatively easy to drill them?Good tip on laying out the 'thick spots' ;o)
Simpson makes a "VGC" epoxy capsule that you drill the hole for, slide it in, and tap the all-thread down on top of. This crushes the capsule and mixes the two parts--super fast and easy. I would dare say the hole needs to be at least as deep as the capsule is long, if not a little deeper.
Lube up lengths of wooden dowels - 1" dia - and locate them where you want the future posts to be. The dowels should extend about 12" above slab.
Pour the footings and the slab.
Once the slab has set, but before it has permenantly grabbed onto the dowels, rotate and slide them out. Now you have a bore to epoxy in a future anchor rod. No need to get out the hammer drill and drill down.
To temporarily seal it, you can get an tapered cork from the hardware store, jam it in the whole and skim it with some concrete/ grout to match the rest of the slab. This way when it is time to access the holes you just have to smash out the 1/2" thick concrete/ grout cap and cork. Much easier than drilling.

Hey Frankie, thanks! The "light" never came on in my head to do that!
No problem.If you have a digital camera, take some process photos. It's a small project but it illustrates a larger concept.Have fun,F
