Concrete threshold repair at patio door

| Posted in General Discussion on
The concrete threshold or step at my patio door has partially Broken away. It was cracked last year and I suppose water got in and froze over winter then broke apart. Can I break away what is left and reform it then pour new concrete. I’m not sure how the concrete is secured or sitting on. Please advise.

Looking at your picture-
are you planning on removing the whole thing? First removing the patio door, then removing all that concrete?
or
Are you wishing to attempt to patch in the portion that's gone?
I might be tempted to do this-
Score and break off the rest of what's there over that coarse of brick. Make it uneven/chiseled like the rest, caulk the small crack (with Urethane caulk or smoosh in a slurry mix of morter) and call it done.
Pouring a patch over the brick to "repair" what was there, probably won't last long
I had no intension to remove the patio door. When builders poor this concrete the doors are already installed so I don't see how the concrete can be under the door sill. I'm just surprised that it's being held in place by just sitting on top of the course of bricks. I had planned to remove all the concrete and pour it again. I just wanted to be sure this will hold.
It's kind of half-arsed -- hard to tell how it's constructed.
If it's an (upside-down) L-shaped piece then you're probably never going to have a good solid connection between the horizontal section and the "skirt".
You should note that apparently the patio below has subsided a bit since the original went in, which is why there's that gap below. But you don't want to place your new piece flat on the patio, since if the patio heaves it will break your new piece off. Better to continue to have that 1" or so gap there.
Frankly, I like Calvin's suggestion -- just break off the rest of the "skirt" (you can make a saw cut along there if you want to clean it up) and call it good.
Actually the patio below was built years later and there was always that 1" gap. It has never settled. I think You guys are correct about just cutting the remaining portion. I can use a saw to make a straight cut all the way across. I plan to re-parg my foundation so what I'll do is parg over the exposed brick below to give it a clean look and prevent the bricking from continuing to crumble.
Thanks guys, great help
