This home was sinking in the back and you can clearly see the sidewalk sinking and the displacement with the concrete. Additionally, the massive stucco crack you see is more evidence of severe settlement.
This is a property in Sherman Oaks with some serious work needing to be done to the hillside. These old railroad tie retaining walls are slipping due to the soil erosion and the home is settling in their place.
This was a mudslide caused by a water leak in the property above this sidewalk. Luckily the DWP turned off the water but it was a little too late and the slide happened anyway.
The concrete footing from the wall above slid down the hillside and came crashing into the wall below.
the path of destruction.
This is where the footing was compromised and the steel post with concrete surrounding it is the only thing left.
The Wall did a pretty good job of holding back the slide, though it will definitely need to be replaced.
This was an old 1900's home in Echo Park that was very brittle. One of our guys tapped the horizontal crack on the concrete foundation and a huge chunk simply fell off.
The rebar in this foundation had expanded due to high moisture intrusion in the concrete. This causes the concrete to break apart due to the exterior pushing pressure of the steel. Most steel with be effected by this unless treated.
You can see this old retaining wall beginning to fail at the top right of the image. Dangerous.
I don't know where they got this sign, but it fits the situation well as the foundation has been undermined and now the home is sinking on the back side.
Poor little guy.
This was a hillside that was showing signs of collapsing. It was very steep and didn't have much vegetation to hold it up. We are excavating much of the hillside and putting in a pipe and board system to hold back and tier the hillside.

A parking garage about 20yrs old or less in Phoenix had the same moisture in the rebar. Spalling showed the problem. One corner sunk badly!

This is freaky. My friend is general contractor for a house in hills above San Jose. All the reinforcements and water mgmt he has to do...!

Thank you for sharing, with explanations.

Mr inspector...show anything and everything like this and I will upvote..I'm in the business and love seeing this stuff

I'll keep'em comin!

I wonder how many of these would just be better to demolish and rebuild from scratch? I can't imagine that they can be made 100% sound now.
avastmehearty
Can be harder to permit a tear down, even one wall retained from original structure can make it a remodel instead of new construction
valen00
with enough steel and glue you can do anything, question is if it's cost effective ;->

I live in Sherman Oaks. The hills are littered with houses built too close to the edge.

Always cracks me up what people consider a proper supporting structure

Well ya see, there's a difference between a proper supporting structure and a properly proper supporting structure.

as an0architect who runs his own office your posts are great, love it

Thanks :)

Someone was graffiti-ing "EROSION" right before the wall slid out from under him and only got to "EROS-"

I'm sure that's not the only house that is brittle in Echo Park. Some of those houses are super old.
AlphaStructural
We see more homes in Echo Park/Silver Lake area than probably any other area in LA County. I can totally confirm a lot of them are horrible!

Do you think it's the age of the houses or lack of up keep?

When I see your posts, I think to myself how glad I am that I don't need to have my place inspected and I do my own repairs. Thank you.

This is why we pay high homeowner’s insurance. Stupid fucks.

Theres this bridge i drive on everyday to take good deliveries to steel mill , its so deteriorated , makes me wonder how it supports semis

Is that Sherman Oaks home (Deck over railroad tie retaining wall) on a lake? it looks very familiar.
AlphaStructural
Nope, just the corner of two intersections.

It makes the Earth seem incredibly more fluid. And we're always trying to build up against that.

#11 was obviously built on a slant based on the joisting and foundation level. Which side is the "back" side?

Your weekly posts are the highlight of my week, some of the most interesting stuff posted on here lately, thanks and keep up the good work.

I do hope your highlight on Imgur, not your whole life.

Thank you! I really do appreciate it and i’m very glad you find them so entertaining :)

Agreed; it reminds me of the "mcmansions from hell" blog. I also agree with the other commenter re after shots to show us how it should be!

I enjoy the heck out of them, too! Thank you for posting!

As an insurance agent all I see is NOPE.
TheUnsolicitedDuckPic
Explain please?
KnottyNerd
I've had people tell me, when quoting a new policy, there's no existing damage and when the inspector goes out there it look like this. 1/2
KnottyNerd
Some try to get a new policy to pay for old damage. Hence the NOPE

What does DWP stand for? In the UK we know that acronym as the "Department of Work and Pensions", a Government ministry.

Won’t have rebar expansion destryoying your concrete if you don’t use any rebar!

Its time to invite OP for an inspection.

Geology teacher once said the "prettiest" places to build a home are usually the worse structurally -hillsides, river edge, mountains, or CA

All true, except for the insinuation that California is pretty.

Where in Utah ya live ?

California is massive, so calling it pretty or ugly as a whole is wrong, really. There are areas that are gorgeous and others that aren't

It ain’t bad as long as you’re north of Bakersfield and not in the Central Valley, then you’re all good!

CA IS pretty. I would have love to seen the HWY 101 coast line in the 20's - 50's, not the oil wells in SBA though...

Your teacher was correct, though it can be done very well.
