I think this is limestone - how to repair?
2 Attachment(s)

The two attached photos are of a front stoop. The building is a 120 year old Chicago 2 flat. I believe the stone is Indiana Limestone (everything else around here is at least).

I'm not sure how to approach fixing this. A few Questions-

- Will a concrete mix 'bind' to the limestone sufficiently? Is there any particular mix I should use?

- It looks like to much to quick patch. I think I need a form. Agree?

- Am I better off ripping the entire step out and replacing it? Or to ask it another way, is it worth the time / effort / hassle to remove the step?

First time post, thanks in advance for any help.

Could you post a picture from a bit further back--showing what is setting on top of the slab?

Replacement is the answer---any patch work will fail in a few winters time---

As requested, oh-mike, attached are 4 more pics.

Now that I look more closely I see what is 'on top' is the building. I'm guessing the stoop sits on the the exterior brick wall, similar to the window sill in 'step 6'. Hard to know for sure.

This is a rental building, so I have a different cost / value proposition than if it were my home. I'd take major visual improvement over 50 year lifespan replacement.

Thanks again for any help!

Ayuh,... For the Long term,... I'd think bustin' it out, then form, 'n pour concrete is yer answer...

That should have been replaced when the stoop and stairs were replaced.

Unfortunately I didn't own the place when that happened. I probably wasn't even born yet.
