Concrete/poured form issue & question

[nerd86]

Does this just look like old concrete deteroration or does this look like it was poured from a bad batch etc?

Tricky part is house was build in 47, but was renovated about 6 years ago so I am not sure if this entryway to the basement was poured then or if this was original.

I do know there was a garage that was torn down (old) and it is possible this entryway went from basement to garage. As you can see the house is sided inside the entryway which leads me to believe this was poured 6 years ago during the renovation.

Anyway, any insight on the concrete and the correct way and the quick way to remedy this would be appreciated. One of these days im going to end up knocked out at the bottom of them LOL.

That is the result of years of water damage that someone tried to cover up to make it look cosmetically nice. Water is still leaking through the walls. First thing I would do is try to find out why.

Bad ground slope, clogged downspout etc.

water leaking, effervescing , old concrete breaking down
the way it looks & was formed with boards, I suspect it closer to '47 than 6 years ago

the cast-in horizontal lines on the right and left are from form boards. No one forms like that today so I would say this is original. only thing 6 years old is probably the smoother sections they tried to make look nice. Presumably those areas looked worse than what you can see (which is hard to believe). I with the others, there is water moving through this concrete (liquid and vapor) and what you see is the long term consequence of that

Not sure where you live and what your winters are like, but do you use salt to melt ice on those stairs?

Thank you for all the feedback guys I appreciate it.

Is the only fix to demo and report? Sounds like that is the consensus since clearly the previous owner attempted to do that here ( so it appears).

It is 75 years old. It is not unusual to see that. I don't think it is going anywhere.

i don't know how thick any of that is, but you could try a test area where you grind down to solid material (scarify) and then patch back (with doweled rebar or pins) to make it look better. This assumes something like it being 8 inches thick and you are removing anywhere from 1/2" to 1" of the outer cover to clean it up. If its 4" thick and you are taking off 2", this won't work. If it is 8" thick and you are grinding and it keeps being soft through half of its thickness, this isn't going to work either. It really just depends on the quality of concrete all the way through. Obviously, you need to figure out why this is happening and fix that or else you will be doing this again.
