Vertical cracks in retaining walls can be a serious concern, especially when one section of the wall is completely separated from the adjoining end. This separation can allow the wall sections to rotate away from each other, causing them to settle, shift, and move at different rates and in different directions.
The cripple wall is rotating out of plane and is structurally compromised. With the loss of support, it is no longer effectively carrying loads and is essentially unsupported in place.
And for my next trick I will make this garage float…
CMU block walls commonly fail due to inadequate drainage. Proper drainage is critical to relieve hydrostatic pressure that builds up behind the wall. Effective drainage solutions include installing a swale at the top of the wall to direct surface runoff away from the structure, incorporating weep holes to allow water to escape from behind the wall, and providing subsurface drainage systems to safely redirect water away from the wall.
These wood structural members are visibly compromised. The staining present is a strong indicator of prolonged exposure to moisture. The underlying source of water intrusion must be addressed to prevent continued deterioration.
The subfloor shows significant deterioration from long-term moisture exposure. The affected area appears weakened to the point where it may not safely support foot traffic.
One way ticket to… the crawlspace.
This almost looks like one of those I Spy pages. I spy with my little eye a lunchbox… a ball… a bucket of Purina dog food… and, of course, some expansive soil causing problems.
The porch is showing movement and has visible cracking and separation which indicate an underlying structural problem that require prompt attention.

#7 I think the technical term is 'expensive expansive soil'. Or it should be.
AlphaStructural
😂😂😂
DonIsMe
Keep posting these, @AlphaStructural!
AlphaStructural
Will do!!!

looks expensive
AlphaStructural
These repairs vary by scope, especially if it’s been ignored for a while.

#4 Looks like the carport is the reason that wall hasn’t fallen over yet.

#7 Is the lunch box still available?
AlphaStructural
$25 Take it or leave it.

Damn; that's a steal!

My sister often sends me listings of homes for sale. With photos. Not in the market, so no idea why she does that. Anyway, last one she sent, I pointed out some problems: Retaining wall won't hold up much longer (cracked, leaning, obvious moisture damage), and the walkway (cracked all the way through the center) shows slippage. Things I wouldn't have noticed before I found your page here. Funny; she didn't respond. Maybe she'll stop sending me those listings now!? heh
AlphaStructural
You’re seeing what we see now. Once cracks, movement, and moisture show up together, it’s usually not cosmetic anymore. Your sister might not appreciate it, but you just saved yourself a future headache.

@AlphaStructural What is the proper way to build on expansive soil? Is there one?
AlphaStructural
There is, but it’s always site-specific. Expansive soils move with moisture changes, so the first priority is controlling water at the source with proper drainage and grading, then preventing intrusion at the foundation. From there, the system is designed to accommodate or resist that movement long-term.

Genuinely ya'll helped me learn what to look for when we were house hunting.
The option we picked was not the cheapest, but it WASN'T at the base of a steep hill to the back, down a bank to the front, and already had multiple inch wide cracks in the foundation. The house was 2 years old and looked reasonable otherwise under fresh paint
AlphaStructural
That’s exactly the right call. Location, grading, and existing movement tell you more than fresh finishes ever will. Glad were able to give you some tips!

As a homeowner, these are the most soothing posts. So glad I don’t live in any of these places.
AlphaStructural
Glad to hear it. Most of these issues are preventable when caught early.

Thank you for these. I want to write an urban fantasy story where a supporting character is a cryptid that works as an assessor after he saved a human assessor who came into his crawlspace. Who better to hire than a creature who's lived under buildings for centuries? Sure, he had to get trained on engineering, but he had the eye and experience. I'm just... really paranoid about getting the language correct when he talks about his day at work.
AlphaStructural
A crawlspace-dwelling assessor with centuries of field experience might actually be the most qualified one there. As long as he’s talking about load paths, drainage, and soil conditions, you’re on the right track. 😏
pluralone
I'd read that story! <3
TheFastpaws
There is a hole in my front porch you can't see the bottom of.
AlphaStructural
Send us a pic! 😏 If it has depth and no clear bottom, that’s typically loss of support below. Not something to ignore, worth getting it evaluated before something worse happens!
TheFastpaws
I would but I can't without poking a hole in the silicon topping my landlord put on it. I do remember being unable to see the bottom though when it was sunny. I never used a flashlight on it when it was open though.
PlainBill
Just use some spray foam to seal it back up. /sarc
