How can I properly address my crumbling concrete footing in my half finished basement, considering adding wood trim and molding for a more finished look?

Hey, so the concrete footing in my basement is starting to crumble, and I’m wondering what the best way to fix it is. My first idea was to cover it with wood trim – maybe start with some dimensional lumber and then add some molding for a more polished finish. I’m open to any suggestions or thoughts you might have – thanks in advance!
You might want to bring in a mason to take a look at that. Trying to reinforce or cover it with wood won’t address the underlying issue and could lead to more problems down the line.
Do you still think the same even considering the foundation is over a century old? I believe it may not be a significant issue but rather the aging concrete
This home was constructed in 1922
I would consider looking deeper into the issue, as sometimes it may not be visible at first glance. Just a thought – perhaps the problem is related to water drainage affecting the entire foundation, but only the brittle/soft/dry part is visible. Alternatively, the concrete could be deteriorating due to its age, slowly wearing away. It’s similar to rust on metal – it holds until you touch it. I’m not an expert, but having owned century-old homes, I’m always cautious with foundations. Hopefully, it’s nothing serious!
I’d recommend using a mortar mix and a margin trowel to parge. Gently tap with a hammer to remove any loose parts, then clear up with a shop vac. Using a bonding agent before parging is a good choice. Another option is to dampen the surface slightly, blend it with a brush, then parge over the damp area (not soaking wet). Best of luck!
Do you know what that black surface is? If it’s acting as a barrier, the deteriorating footer might be caused by moisture getting trapped underneath. The only way for it to escape is through the footer. It might be necessary to remove the black material and install a raised floor to allow proper ventilation for the concrete slab.
Recently opted for affordable indoor or outdoor carpeting. It was installed a couple of weeks ago and has not affected the foundation.
First step is figuring out why this is happening, unless you’re a real estate investor. Give a mason a call. My guess is water seeping through the wall from the outside.
I believe it’s simply due to its age – the house dates back to 1922 and I haven’t noticed any signs of moisture even after heavy rainfall
There must be a specific reason for the deterioration of the brick, and I haven’t come across age being a factor before.

I suggest picking up some mortar mix and using a margin trowel for application. Lightly tap away any loose pieces with a hammer and then clean up the debris with a vacuum. Before starting the parging process, it’s a good idea to use a bonding agent. If you don’t have one, you can moisten the surface slightly and blend it with a brush before applying the parging mix—just ensure it’s not too wet. Good luck!

The issue lies in the quality of the cement used, along with minor water leaks and temperature fluctuations that are causing the concrete to deteriorate. To fix this, consider getting proper insulation installed on the outside or using special products to prevent moisture damage. It’s best to consult a specialist for this, even though it might be a bit pricey. Ignoring it could lead to more severe problems and even higher costs down the line.
